11 months ago - Added ModelEntity.HasTexture, which is true if Texture != null and IsTextured is true. I think this is worth having just because of how many places both comparisons are made in.
- Added GeomMath.ExtractRotationSafe extension method, which returns Quaternion.Identity in the scenario that one of the matrix scale components is 0 (which normally results in a NaN Quaternion).
- AnimationBatch functions now have a simulate parameter, which skips updating the models MeshBatch if true.
- Replaced ModelPreparerExporter.GetModels with GetPreparedRootEntity(..., out models). It's an ugly setup right now, but cloned root entities are needed for animations. And having a method to GetRootEntity and GetModels would be confusing with whether you need to pass the original or prepared root entity to GetModels.
- ModelPreparerExporter.AttachLimbs no longer affects the original model.
- ModelPreparerExporter now exports tiled textures with dimensions that are powers of two.
- Added GeomMath.RoundUpToPower to help get rounded up powers of two.
- Added NeedsTexture(model) shorthands to all model exporters. This returns true if ExportTextures option is true, and if model.HasTexture is true.
- glTF2 no longer exports TEXCOORD_0 when model is untextered.
- glTF2 now exports initial model rotation.
- glTF2 now exports initial model WorldMatrix transforms, instead of LocalMatrix transforms.
- Changed glTF2 file prefix from obj to gltf.
- glTF2 now only computes animation frames once per frame (instead of 3 x models.Count per frame), and now stores the resulting transform components for each model at each frame.
- glTF2 bounds calculation now goes off local vertex positions, and also swaps min/max and negates for Y/Z.
- glTF2 now restores animation loop mode when done with the animation batch.
