mago-3d-tiler v1.10.0

[Changed in version 1.10.0]

In this release we wanted to improve memory issues with the overall large data conversion process.
We have lightened the point cloud tile results and made it possible to convert larger point cloud data.
We also made the CityGML conversion more compatible.

[Feature Additions]

• Support for converting large point cloud files
  Improved memory stability by changing the way points are stored in temporary files during conversion instead of in memory.
  which is more memory stable, but slower.

• Apply quantisation to point cloud tiles. Quantization the resulting data to make it lighter.

• Changed point cloud options to include.
  Removed the --pointSkip and --pointScale options.
  Added an option to convert to point cloud source-level point counts Available with options --sourcePrecision, -sp
  Added option for percentage of points relative to the point cloud source
  --pointRatio {100}, -pr {100}
  Available as options Values from 1 to 100, default is 50%

• Changed option to fix Y-UP Axis Z-UP Axis issue, added as X-Axis rotation feature,
  Using --swapUpAxis, --flipUpAxis options is now not recommended, will be removed in next release.
  Can be used with --rotateX {degree}, -rx {degree} instead

--swapUpAxis -> --rotateX "-90.0"
--flipUpAxis -> --rotateX "180.0"

Note that the ‘-’ character can cause problems with negative separators and option separators.

• Added transformation offset options

--xOffset {X Offset}
--yOffset {Y Offset}
--zOffset {Z Offset}

When transforming data, you can give an offset for each axis. Units are determined by projection.
Also available as :

-xo {X Offset}
-yo {Y Offset}
-zo {Z Offset}

• Reduced memory usage for Shape and Geojson conversion features.
• Improved CityGML conversion compatibility, now converts most tags.

[Feature Improvements]

• Fixed memory leak when converting assimp. (improved memory usage)
• Embed point cloud TransformMatrix in pnts file instead of tileset.json to reduce json file size.
• Improved point cloud geometric error calculation.
• Improved GaiaTexCoordCorrector function. (more compatibility)
• Improved Gradle project structure for OpenGL add-ons (Parent-Child structure) .
• Added arm64 architecture docker option.

mago-3d-tiler v1.9.0

[Changed in version 1.9.0]

We've enhanced the overall functionality based on issues and questions.

[Feature Additions]

• Added TextureCoordinate correction (toPositiveQuadrant)
  Added a feature to correct the TextureCoordinate of a 3D Models.
  Textures are no longer crushed when creating B3DM.
• Tessellator improvements.
  Tessellation with holes is now applied to 3D Tessellation.
  This allows for better conversion of CityGML, Geojson, and Shape.
• When converting to CityGML, window and water classification now convert diffuse color to translucent.

[Feature Improvements]

• Minor performance improvements when saving/loading GaiaSet (by applying a buffer to the I/O).
• Fixed bug with resizing copied texture images.
• Fixed conversion failing when pipeline is less than 100.
• Fixed “Double” parsing bug based on system locale (for decimal comma separator)

mago-3d-tiler v1.8.1

[HotFix 1.8.1 Change Log]

• Change to add attributes when converting pipes
• Handling nulls on ASCII conversion failures

[Changed in version 1.8.0]

This release is an overall enhancement.
Tessellation was enhanced to make CityGML more convertible.
For pipes, we chose diameter and millimeter (mm) units to align with more commonly used specifications

[Feature Additions]

• Implemented LargeMeshConverter as an experimental feature for converting large meshes, applicable with --largeMesh or -lm option
• Improved tessellation functionality, now supports three-dimensional tessellation with innerings.
• Improvements to better convert CityGML format (tessellation, classfication)
• Fixed to save all attribute values of original features when converting ESRI Shapefile and Geojson files

[Feature Improvements]

• Modified pipe creation logic, changed to more appropriate units for pipe data
  changed radius -> diameter command option to --diameterColumn <arg> or -dc <arg> instead of -radiusColumn <arg>
  changed to use Millimeter (mm) as the default unit
• Changed i3dm tiling threshold (number of triangles -> number of instances)
• Modified the structure of Common Module 3D Scene Structure
• Fixed temporary file creation to use Serialize when creating temporary files
• Minor syntax and fixes

mago-3d-tiler v1.7.0

[Changed in version 1.7.0]

Converted several samples, including data provided through issues, to improve the overall command input convenience and stability of the conversion function.

[Feature Additions]

• Added the feature to convert Shape Polyline data to Pipe. It is possible to convert Shape with 3D Position and 'radius' attribute.
  You can also specify the radius property name directly with the -columnRadius <arg> option.
• Added manuals for frequently used conversion cases, see manual.md file

[Feature Improvements]

• Apply EPSG:3857 coordinate system when -crs is not entered.
• Fixed the UP-Axis option. Before change -yUpAxis After change -swapUpAxis, -flipUpAxis
  It can now replace most Up-Axis cases.
• Fixed to better recognize embedded textures.
• The Tiler now infers the inputType from the filename without you having to enter it.
  If a KML file is present, it will be read first and if there is a mix of other 3D file formats, the first recognized data will be converted to inputType.
• Optimized GLTF conversion by fixing some bugs.

[Notes]

• It has been reported that macos version behaves abnormally after M1 chip.
  This is because the Lwjgl library does not yet support Apple's M-series architecture.

mago-3d-tiler v1.6.4

[Changed in version 1.6.4]

  PolyLine data with 3D position information and "radius" property value will be developed as a function to create it.

mago-3d-tiler v1.5.1-release1

[Hotfix]

Fixed a bug in the FileLoader and temp image loading.

• When the path to a texture file is absolute, if an image does not exist in that path, it is handled as a relative path instead.
