Simplygon 10.0.1400.0
New features
API
Modular seams, enabling gapless reduction between modular assets
Support for quad reduction
- Feature overview
- Quad support in GeometryData by linking adjacent triangles with the new QuadFlags triangle field.
- FBX importer/exporter populates and uses the QuadFlags field to import and export quad geometry data.
- OBJ importer/exporter populates and uses the QuadFlags field to import and export quad geometry data.
- USD importer/exporter populates and uses the QuadFlags field to import and export quad geometry data.
- Quads that pass though the triangle-based processors are maintained when possible, but will convert to triangles as required by mesh modifications and reduction operations.
- Triangles which are marked as part of quads are automatically quadrangulated on export.
- GeometryData::ValidateQuadFlags() can be used to check the validity of user-set quad flags.
- Quad reduction processor and pipeline
- New processor/pipeline that works on structured quad meshes and collapses entire strips of quads at a time.
- Appropriate for LOD0 reductions as structured input -> structured output.
- Settings for basic reduction targets; Ratio, Count, MaxDev, OnScreenSize
- Limitations
- May stop reduction ahead of reduction target if no more acceptable collapses are found.
- Does currently not behave well on unstructured quad meshes, works best on authored content with regular topology.
- Primarily tries to remove quads in geometry with mixed polygon types, and ignores triangles unless they are adjacent to quads.
- Count and Ratio reduction targets will include triangles in stop condition calculation.
- VertexWeights are not supported. The field must be removed completely from the geometry as it being present leads to unpredictable behavior.
- Vertex welding is not yet supported.
Tessellated Attributes in API
- Added support for per-triangle implicitly stored tessellation of attributes in geometries. Supported by all processors, casting opacity and displacement (scalar or full vector displacement data)
- VDM (Vector Displacement Maps) floating point maps (.tiff & .exr formats) can be imported and injected into displacement data in tessellated attributes
Max
- Added support for quad export and import
- Added support for QuadReductionPipeline
- Added Simplygon 9-10 migration guide
Maya
- Added support for quad export and import
- Added support for QuadReductionPipeline
- Added Simplygon 9-10 migration guide
License updates
- New license type "Standard" added which is more resilient to license server outage.
Improvements & changes
Distribution
- Improved container support
- In container environments, Simplygon will fallback to CPU if GPU is not available.
API
Import/export
- General N-gon polygon faces are automatically triangulated, and quad information is kept on import.
- Added support for .exr file format input
- Full support for importing, casting and exporting floating point texture data (in .tif and .exr file formats)
- FBX exporter automatically compresses attribute fields using IndexToDirect.
- RunImport and RunExport are renamed to Run and now returns EErrorCode, to harmonize with processors.
Scene data
- Scene nodes now always generate guids for unique look up
- Added BrightnessContrast and ColorCorrection nodes to shading network
- Texture, material, bones and selection set tables now enforce unique names when adding or setting items.
Error handling
- Error handling now supports recoverable errors in extension to the regular (unrecoverable) errors.
- Recoverable errors from processors, importers and exporters are returned as EErrorCode enum values.
Documentation
- Clarified what features are supported in what integrations.
