The dalai-suite offers a toolbox for large scale 3D models manipulation, processing, conversion and geographical registration. It is mainly designed to offers solutions suitable for models that can weight hundreds of gigabytes and that are used in the domain of environment survey and land registering. It was initially developed to offer the required tools needed to allows massive data processing and preparation for the eratosthene framework.
The dalai-suite uses a common and very simple format for all the implemented tools that is also used for the Eratosthene Project. This format offers a simple way of storing massive amount of graphical primitives. This allows the dalai-suite to manipulate all sort of 3D models, from large scale point-based models to more refined vector models.

The dalai-suite comes also with tools dedicated to models visualization and large scale models processing such as automatic segmentation, cleaning, geographical transformation and assisted geographical registration.

The dalai-suite also comes with a set of tools dedicated to file format conversion that allows data coming in their specific formats to be converted in the suite format.
Each implemented tool of the suite comes with its own documentation that explains the implemented solution and gives examples of usages and results :
Display tools
Models automated filtering and cleaning
Models automated transformation and editing
- UV3 file translation
- UV3 file geoid heights conversion
- UV3 file height-based coloring
- UV3 file hashing
Models format conversion
A detailed documentation of specific file formats used by the tools of this suite can be found of the format page.
