@kcoley , before accepting this, can you or someone else confirm that UsdTransform2d is honored in the Apple software suite (especially the MacOS and iOS viewers)? Thanks! |

Hi @spiffmon ! Yes, I can confirm this works on iOS and macOS (I tested the asset I created with ARQuicklook on iOS and with Preview on macOS) |

Terrific - thank you! |

[hd, hdSt, usdImaging] Change the format of UsdImagingDelegate::Get("/PointInstancer", "rotate") to VtArray<GfQuath>, to match SamplePrimvar; change expected hydra quaternion layout for "rotate" from (r,i,j,k) to (i,j,k,r).
Quaternions in USD are stored as GfQuath arrays, with (i,j,k,r) component layout. Before this change, UsdImagingDelegate::SamplePrimvar() would return an array of GfQuath for the "rotate" primvar on a point instancer; however, UsdImagingDelegate::Get() would convert the quaternions to GfVec4f format, with (r,i,j,k) component layout. The main motivation for this change was to resolve the API incompatibility, by having Get() return an array of GfQuath as well.
In order to not need to rewrite the array in processing, this code also adds half vector and quaternion support to HdVtBufferSource and hdStorm; GfQuath is now interpreted as a 4-component vector of halfs-floats, and hydra can transport this data all the way to the GPU. This saves us the array copy, and also saves us some GPU memory and bandwidth since the data is sent packed.
hdStorm half support is implemented with GL_HALF_FLOAT for vertex attributes. For other binding points, like SSBOs, the half floats are sent as uint[] and unpacked by the generated HdGet_ functions. Ext-computation output to half-float vectors is also supported. hdStorm only supports half2 and half4; half1 and half3 are omitted since they are more complicated to index into.

Fixes for Docker image used for PyPI generation
- Pin the manylinux image to a specific tag. This avoids
mysterious segfaults that occurred when trying to use
the generated PyPI packages outside of the docker
container.
(The segfaults appear to be due to some kind of missing
symbol error in TBB, but I haven't dug much further.
I also did not bisect the manylinux images to determine
the last one that did not have this issue)
- Remove CMake build step. The manylinux image used here
has CMake 3.20 installed, so we don't need to build
CMake ourselves. This avoids an "expired certificate"
error when trying to download the CMake source via wget.

Add some needful validations to usdchecker:
- No Boundables under Gprims
- No non-container Connectables under anything other than a connectable
container
- All textures that feed UsdPreviewSurface's _normal_ input should be
recognizably linear encoding for 8 bit images, which should also
set inputs:scale and inputs:bias appropriately. We cannot properly
recognize linear 8-bit images without a plugin to perform image
loading and interrogation, which will come in a followup change. So,
for now, we formulate the linearity check as a warning rather than an error.
- Require more stage metadata
Issuing warnings required some boilerplate for introducing the concept to
the Rules and ComplianceChecker, and updating the two calling clients.
Also cleaned up and corrected some flat-out wrong rule descriptions,
comments, and logic:
- The check for authored upAxis = 'Y' for consumer content was not actually
validating the data was authored, so in most installations it wasn't actually
checking anything
- Texture asset checks were only being performed on Shader prims, but they
are legal for all content classes on other Connectable prims such as Materials,
so we now test all Connectable prims.
- Provide scene paths in error messages wherever relevant
- Make the texture check sensitive to consumer content mode and whether
asset is a usdz package, since they affect what formats are legal.
- Changed format of "--dumpRules" to provide the rule names, so that
error messages referring to rules by name are more useful.
TO DO:
- complianceChecker logic really needs more unit testing for new checks
- More asset level checks (such as rel and conn target encapsulation) and model
hierarchy checks would be useful.
- PrimEncapsulationChecker should validate that Connectable containers that enforce
encapsulation actually do encapsuate their networks.

Avoid calling ArResolver::OpenAsset multiple times when
opening a .usd layer.
This change adds private API to the .usda and .usdc file

Let hdSt draw BasisCurves that don't completely cover the
supplied points or other primvars.
If the client supplies a primvar that doesn't meet one of the size
criteria, a fallback primvar value is used instead. Previously,
the valid authored size options were:
a) Size 1
b) Size equal to the number of elements implied by the topology and
primvar class specifier (varying or vertex)
c) Size less than the number of vertices, provided there are curve
indices supplied
Now, we adjust (b) for curves with curveIndices. If a client supplies
indices (which specify a specific point index for each vert, in arbitrary
order, with multiples, and possibly not covering the whole points
array), primvars larger than numVerts are now permitted, and
the primvar is truncated according to the primvar size implied by
the topology and indices.
Varying primvars of unexpected size are still counted invalid.
Vertex primvars of unexpected size and lacking indices are also still
counted invalid, as this is more likely an authoring mistake than
an intentional sparsification as would be the case with indices.
This strictly increases the configurations that are valid.
This change does not tackle deindexing or compacting large
primvars which are only sparsely used, because at the moment
we have no mechanism in place for aliasing point IDs for drawn
points.

Users can now specify "--use-cpp11-abi={0, 1}" to set the
_GLIBCXX_USE_CXX11_ABI define to the given value when
building USD and its dependencies. This allows users to
override their compiler's default ABI setting, which
may be necessary to match other libraries that link
against USD.
There should be no difference in behavior if this
option is not specified. By default, build_usd.py will
not define this macro one way or another to allow the
compiler to use its own default setting.

[hd] In SceneIndexAdapter, add a 1-entry LRU cache for locators -> dirty bits translation.
HdDirtyBitTranslator attempts to optimize the locator to dirty bit translation process, but it was still showing up in traces specifically when we invalidate the whole scene (due to, e.g., root level xform or visibility controls). In those cases, we'll have 100k calls in a row translating a single locator to a single dirty bit.
Adding an LRU cache to the translator vastly speeds up those invalidations, without really affecting typical frame-advance invalidations (which are more heterogenous).
Note: currently, the cache only applies to rprims.

UpdateSchemaWithSdrNode now adds shaderId attrSpec with default value corresponding to sdrNode identifier
- usdgenschemafromsdr is updated such that schemaConfig now provides a renderContext ("ri" for renderman nodes as an example), this is then passed down to UsdUtilsUpdateSchemaWithSdrNode which uses this information along with SdrShaderNode's context field to create an attribute spec for shaderId and assigns it the shader's identifier as a default value.
- cleaned usage of string constants in usdgenschemafromsdr
Note that we need to provide identifier (overrideIdentifier parameter) to be used for sdrNodes which are queried using explicit asset paths. This should only be used when clients know the identifier being passed is the true identifier which sdr Runtime will provide when querying using GetShaderNodeByNameAndType, etc.
This change also updates the usdRiPxr schemas by appropriately running the updated usdgenschemafromsdr on the "updated" rman schemaConfig.json files.
- also updates these schema to reflect changes from usdLux sdr nodes only having core types properties and shadowAPI and shapingAPI properties.

[usdImaging] Fix GprimAdapter::_AddRprim material resolution order to be consistent with other functions.
In GetMaterialId (on instancers and gprims) and GprimAdapter::UpdateForTime, we consider the local material binding to take precedence over the instancer material binding. This is consistent with the basic USD rules, where more local material assignments take precedence. However, this was flipped in _AddRprim, which would preferentially take the instancer material binding.
For many scene structures, this wasn't causing issues, since only one of the material bindings would be non-empty; or they would point to the same path, which is sketchy but worked in practice. However, this specifically fixes a bug concerning scenes where a point instancer prototype is marked as instanceable, and the material bound to the prototype is inside the instance; in this case, the old code would have a disagreement about whether the material was named /World/path/to/material or /Prototype_N/path/to/material, and so the relationship in hydra would be broken.
Fixes #1626

Updates to the SdrShaderNodes that are generated for concrete UsdLux types
1. SdrShaderNodes are only generated for concrete UsdLux library light types. We no longer generate nodes for the empty UsdLuxLightFilter and therefore any light filters.
2. ShadowAPI and ShapingAPI input attributes are now included in every light type's shader node.
3. The shader nodes for these lights will no longer include inputs that come from auto-applied API schemas (like the auto applied rman API schemas).

[ar 2.0] Make ArResolver::GetModificationTimestamp optional
ArResolver now provides a default implementation for
ArResolver::GetModificationTimestamp that just returns an
invalid ArTimestamp.
SdfLayer no longer requires a layer to have a valid timestamp.
Previously SdfLayer would issue a coding error and fail if a
timestamp could not be retrieved, even if the layer itself was
opened and read successfully.
The timestamp was used by SdfLayer::Reload to determine if
a layer had been changed externally and needed to be reloaded.
SdfLayer::Reload will now consider any layer with an invalid
timestamp and any layer with external asset dependencies with
invalid timestamps as "dirtied" and will always reload that
layer.

Allows for shader writers to explicitly provide the Sdf type associated with SdrProperty
- This can be provided by setting the sdrUsdDefinitionType field in the shader to the appropriate sdf type.
- Note that there is an assumption that the default value set on the
such a property is in accordance with the SdfValueTypeName set in
SdrUsdDefinitionType metadata. Hence we wll try to cast the VtValue to the appropriate sdf type.
- Introduces _sdfTypeDefaultValue member on SdrShaderProperty which is
set in _ConformSdfTypeDefaultValue. GetDefaultValueAsSdfType() can be used to access this value.
Note that GetDefaultValueAsSdfType on the base NdrProperty returns an empty
VtValue, in allignment with the implementation of NdrProperty::GetTypeAsSdfType
- GetDefaultValue() returns the parsed sdr default value, though some minimal conformance check
and correction are applied as part of _ConformSdrDefaultValue.
- XXX: Note that for backwards compatibility we currently override the value of _defaultValue with
_sdfTypeDefaultValue and this specific code is guarded by an envSetting. Once all appropriate code sites
for GetDefaultValue are updated to use GetSdfTypeDefaultValue, this envSettings and the backward compatibility code should be removed.
- Included a test in schema gen through sdr to use this feature.

[usdImaging] Fix a possible crash when invalidating items, then deleting them, then drawing.
UsdImagingDelegate uses _dirtyCachePaths to maintain a list of prims to call UpdateForTime on, based on recent invalidation. When prims in the underlying stage are deleted, we don't prune this list (for efficiency of removes), which means that it's possible for _dirtyCachePaths to point to nonexistent prims. Previously, this would trip an assert; this CL relaxes the assert.

hdPrman should use RtxHioImage for lightColorMap.
We want the ability to pass asset paths that refer to things other than
.tex files on disk to prman for the lightColorMap property on lights.
We can do this by using the RtxHioImage rtxplugin but there are three
complications:
1) We must distinguish (at least) .tex files. Users will
not be able to read them via HioImage so these asset paths must be
passed directly (without using rtxplugin).
2) Unlike other textures, lightColorMap textures should not be
flipped vertically.
3) Only image assets should use RtxHioImage.
This change changes hdPrman/light.cpp to use the RtxHioImage plugin
with flipping disabled for resolved asset paths that don't have a .tex
extension for the texture:file input. It also changes material.cpp
to use the RtxHioImage plugin for resolved asset paths that don't have
a .tex extension, and are either image assets on disk or for a light's
texture:file input. This is a heuristic: an unresolved asset path is
probably (?) a relative path for RMAN_TEXTUREPATH to find, and a
resolved asset path that has the "tex" extension could really only
be a .tex file on disk.
If the resolved asset is on disk then we can check to see if it's an
image. If it's for a light's texture:file we know its an image and
it must not be flipped.
This change adds a new TfDebug code, HDPRMAN_IMAGE_ASSET_RESOLVE, that
prints resolved image asset paths. It's now used for lightColorMap,
assets in materials, and material filters.

[ar 2.0] Require Unix time for asset modification times
ArResolver implementations were previously free to use any
object to represent an asset's modification time as long as
that object could be equality-compared to determine if an
asset had been modified. This provided maximum flexibility.
However, with the introduction of URI resolvers in Ar 2.0,
clients may now be working in environments with multiple
active resolver implementations. In these cases, allowing
each implementation to use different objects for timestamps
would restrict the ability to compare timestamps from
different assets, e.g. to determine if one asset had been
more recently modified than another. This is not something
the USD core currently does, but could be useful in various
pipeline use cases.
To enable these comparisons, Ar now requires asset
modification times to be represented using Unix time. This
change modifies ArResolver::GetModificationTimestamp to
return a new ArTimestamp object which documents this
requirement. Client code in the core has been updated to
accommodate this API change.

[Hd] PrimDataSourceOverlayCache: don't use a per-prim TBB datastructure.
PrimDataSourceOverlayCache holds, per-prim, a series of attributes that have been computed and added to that prim. Those new attributes are currently living inside a tbb::concurrent_unordered_map, but it turns out this is super expensive. It's also not needed in current uses of the PrimDataSourceOverlayCache, since hydra has a (mostly) strong guarantee of only one thread accessing each prim.
We'll need to revisit this if we add hierarchical computations to PrimDataSourceOverlayCache, but at that point we have many solutions that aren't as expensive as a TBB datastructure.

HasConnectableAPI() now does a full search.
Previously this function (on UsdShadeConnectableAPI) would only check a
cache. If the type hadn't been cached already then the function would
return false even if it would've been true after caching. Now we do
the full search algorithm from GetBehavior() to fill the cache if
necessary so clients are no longer on the hook to call GetBehavior()
(indirectly) to get the right results.
The change moves the code from GetBehavior() into another function and
has GetBehavior(), GetBehaviorForType() (which HasConnectableAPI()
calls), and GetBehaviorForPrimTypeId() call the new function.
Please note that this makes GetBehaviorForPrimTypeId() and
GetBehaviorForType() significantly more expensive if the result isn't
cached. This is necessary to get the correct answer.
testUsdShadeConnectableAPIBehavior was changed to reflect the new
behavior. One part of a test became redundant and was removed while
parts of two other tests that depend on the new behavior were enabled.
A type lookup bug was also fixed; this bug prevented a couple of
tests from checking what they were intended to check.

[hd] Re-enable Scene Index Emulation.
Scene Index Emulation is a major new imaging feature. It was originally turned on in CL 2185534, but due to some performance issues it was disabled in CL 2186347. We've addressed many of the performance issues now, so we're re-enabling it. We expect to continue working on performance after this CL, though.

Tweaks for specifying build variants in build_usd.py
- Restored default build variant to 'release'. This was
changed to 'relwithdebinfo' in change 2184287 but in
hindsight it seems a little odd for the default to
not be 'release' and produce a potentially much larger
build due to the inclusion of the debugging info.
- Removed individual build variant flags to minimize the
(growing) number of command line arguments to the build
script. Users now specify the build variant with:
'--build-variant {debug, release, relwithdebug}'
- Small refactor to provide more readable description
in summary and remove unnecessary function.

[hd] Streamline HdFlatteningSceneIndex PrimsAdded and PrimsDirtied calls.
- When we get an Added/Dirtied for primPath and invalidate its subtree, don't generate a dirty notice for primPath since that's redundant.
- The wrapper invalidation now takes a locator set, and we filter for relevancy against a locator set. This reduces the number of times we translate back and forth.
- If we're invalidating a subtree and a prim doesn't have any cached data, don't invalidate its children, on the assumption that they didn't reference this prim for their value computations. (This particularly helps avoid large invalidations before the scene is populated).

Fixed bug that could cause UsdNotice::ObjectsChanged notice
emitted after a call to UsdStage::Reload to contain pointers
to destroyed objects, leading to invalid memory accesses
when calling certain methods on the notice.
Change 2175340 added a batching mechanism for processing
changes in UsdStage, primarily to allow stage changes that
occurred during a call to UsdStage::Reload to be combined
into a single round of notification. These changes could be
due to a resolver change, or layers being reloaded.
In the latter case, UsdStage::_HandleLayersDidChange would
save pointers to data in the SdfNotice::LayersDidChange
notice it received so they could be included in the
ObjectsChanged notice emitted in _ProcessPendingChanges.
However, _ProcessPendingChanges would be called *after* the
LayersDidChange notice went out of scope, leaving the
pointers in the ObjectsChanged notice dangling.
This fix makes UsdStage::_HandleLayersDidChange process and
send out the ObjectsChanged notice immediately to ensure the
LayersDidChange notice is alive when the ObjectsChanged
notice is sent. This should still result in a single round
of notifications if UsdStage::Reload causes resolver change
and layer reloads, since the layer reloads happen after
the resolver changes are processed.

[hd] Speed up UsdImagingDelegate::Sync() when some of the request paths are not present.
In scene index emulation, UsdImagingDelegate::Sync() can receive prim paths of other delegates. If we discover these, we want to continue to the next prim path as soon as possible. Previously, the first thing we did with these paths was to convert index -> cache path, and then check if the prim info was present. However, if the prim info isn't present, the index->cache path map entry won't be present, and we'll do an SdfPath::ReplacePrefix before discovering that the primInfo map is empty.
Now, we directly look at the index -> cache path table, skipping the ReplacePrefix. If we don't find the path translation entry, we know the prim info doesn't exist, since the two datastructures are maintained in parallel.

Changing the built-in UsdLuxLights to inherit from the correct UsdLuxBoundableLightBase or UsdNonboundableLightBase instead of UsdLuxLight.
Inherits from BoundableLightBase - CylinderLight, DiskLight, PortalLight, RectLight, and SphereLight.
Inherits from NonboundableLightBase - DistantLight, DomeLight, and GeometryLight (deprecated)
PluginLight is special and inherits directly from Xformable and has a built-in LightAPI.
This change also deprecates GeometryLight.
Note that all lights do still inherit from UsdLuxLight as the two base classes still do. This will be changed in the near future to completely remove UsdLuxLight.

Removes topology caching from prim-level data source to shared amongst children of new "mesh" and "basisCurves" data sources and schemas.
By having meshTopology and geomSubsets as children of the prim-level container data source, we had multiple existing HdSceneDelegate calls repeatedly querying for meshToplogy.
The existing solution cached topology data sources as member variables of the prim-level HdLegacyPrimDataSource. This increased memory usage.
By introducing an additional level of nesting ("mesh" and "basisCurves" container data sources), we can share the result of a single call to GetMeshTopology among data sources beneath.
This lives as long as any of those data sources instances are alive rather than the lifetime of the prim.

Improve Storm's 1st order approximations of the basic UsdLux area lights.
SphereLight, DiskLight, RectLight, DistantLight, and CylinderLight
now provide an approximation of the direct lighting response of
their path-traced area light forms, including controls for:
- intensity, exposure, color temperature
- diffuse and scalar multipliers
- geometric controls, normalization, and directionality
- cone angle and cosine focus
Visibility on these lights also now works.
A major difference is that previously these lights did not
attenuate with distance; now they do. As a result, tests
that used UsdLux lights with Storm have been updated to
produce similar visual results in-camera.

[hd] GetInstanceIndices() speedup: cache the top level instancer topology datasource.
This change caches the Hd_InstancerTopologyDataSource, primarily so we can cache the result of GetInstancerPrototypes and the translation of said value to a VtArray. Those two operations can end up being surprisingly expensive, since if we do them once per prototype rprim we end up with O(#prototypes^2) SdfPath copies and some of our scenes are very highly instanced.
Caching with an atomic guarantees we get some caching and answers are always correct, but if there's contention in _GetInstancerTopologyDataSource we can end up doing duplicate work. In some unscientific testing, this version is a bit slower than synchronizing on a mutex (1.3x on one of our highly instanced sets); but it benefits from not having a std::mutex per prim, which would cost a lot of memory. With this change, the runtime of GetInstanceIndices() is once again reasonable and no longer the tall nail in our traces.

GetInstanceIndices was implemented naively in emulation, construcing the whole instancer topology for each prototype. For highly branched instancers, this can explode the runtime of this call.
