Version 8.1 ​

  • Additions to the API -ImageComparer: New tool for comparing renders of LODs (or anything else really) to ge a difference metric. Suitable for automatic testing.
  • Changes to the API
    • Visibility: No longer requires DirectX binaries or graphics hardware.
    • Parameterizer: New parameterization algorithm, generally much better results.
    • AggregationProcessor: Triangles using tiled textures can now be subdivided along the UVs to get much better aggregated textures at the cost of higher triangle counts.
    • AggregationProcessor: Visibility support.
    • AggregationProcessor: Better handling of input texture chart aspect ratios.
    • RemeshingProcessor: Increased performance when remeshing certain types of objects.
    • OcclusionMeshProcessor: Visibility support.
    • OcclusionMeshProcessor: Support for skinning transfer.
    • OcclusionMeshProcessor/ShadowMeshProcessor: These have been multithreaded to a larger extent than earlier, so larger target sizes are possible. Still requires DirectX.

  • Bugfixes

Version 8.0 ​

  • Additions to the API
    • Remeshing: It is now possible to set a clipping geometry, which can be used to perform boolean operations on the process geometry. Like clipping plane, but using geometry.
    • Remeshing: MergeBoldness setting added to control the aggressiveness of the merging set with MergeDistance. Defaults to 0.5, set to 1 to replicate old behavior.
  • Breaking API changes
    • Materials: Materials and textures can now only be defined by using shading networks, the old legacy material system has been removed.
    • MaterialCasters: The IsSRGB flag has been removed and replaced with the OutputSRGB flag, to better correspond with its actual function when using node-based materials.
  • Bugfixes

Version 7.1 ​

  • Additions to the API
    • Aggregation: Chart aggregation now support per-vertex weights for texture sizing.
    • Remeshing: AllowTransparencyMapping flag in the mapping image settings now allows for low-res remeshings to correctly map transparency to the areas of the texture that should receive it. For example, a fence remeshed into a solid "wall" gets 0 opacity in between original individual boards.
    • Remeshing: You can now get a selection set containing the generated geometry output by the remesher, in complex scenes it was a bit hard to know where exactly it ended up.
    • Visibility: Support for orthographic cameras
    • Visibility: Added PixelFOV setting to regulate the precision of perspective cameras.
    • Visibility: Added OrthographicPixelSize setting to regulate the precision of ortho cameras.

    • Reduction: Added curvature importance.
    • OcclusionMeshProcessor: New processor for generating occlusion meshes for culling passes.
    • ShadowMeshProcessor: New processor for generating shadow meshes for cheap shadow mapping. Very early state, not recommended.
  • Changes to the API
    • All: More settings have been made available to allow fields to be set by name rather than by id.
  • Bugfixes

Version 7.0 ​

With this major release we've taken the opportunity to streamline the API a bit, and hence some old flags and settings have been removed. All old functionality remains.

  • Additions to the API
    • Scene: SelectionSets added. With these, you can selectively process only a subset of a specific scene. Each scene contains a SelectionSetTable, which in turn SelectionSets can be added to. These are references to nodes in the scene.
    • Scene: Plane nodes added. You can now define planes in the scene, and these planes can be used as cutting planes in the remeshing processor, optionally using selectionsets to only use specific planes.
    • Scene: SelectNodes functions for quickly generating selection sets.
    • Scene: CreateChild functions added to SceneNode, for example: node->CreateChildMesh(geometryData). This streamlines scene creation.
    • Scene: Functions for combining all geometry in the scene into a single GeometryData are now available, optionally using a SelectionSet to only combine a subset of geometries.
    • Processors: You can now define a ProcessingSelectionSet to selectively process a subset of the input scene.
    • Reduction: Overhaul of reduction targets and stop conditions. Now supports any combination of the four supported target types: Triangle count, triangle ratio, max deviation and onscreen size.
    • Reduction: Updated geomorph support for completely seamless LOD switches.
    • Remeshing: Now supports multiple and non-axis-aligned cutting planes
    • Remeshing: New EmptySpaceOverride setting enables remeshing of house interiors and caves.
    • BoneReducer: Processing settings overhauled to better correspond with reduction processor settings.
    • Welder: Previously only part of reduction processor, now made publicly accessible.
  • Changes to the API
    • Processors: All processors (ReductionProcessor, RemeshingProcessor, AggregationProcessor, ImpostorProcessor) now only take scene inputs.
    • Aggregation: SceneAggregator renamed to AggregationProcessor. Settings for chart aggregation moved to MappingImageSettings.
    • Reduction: The FeatureFlags settings have been removed, from now on only use the Importance settings.
    • Reduction: The EnablePreProcessing and EnablePostProcessing settings have been removed. Settings for the individual elements are still available.
    • All: Some settings have been renamed to better align with our naming convention.
  • Significant optimizations to reduction and remeshing processors
  • Bugfixes
