[WIP][Test] Add automatic generated LODs (Part 1)
PR Details
UNDER DEVELOPMENT. ITS JUST A DRAFT.
This PR Brings an LOD Generation Tool (MeshDecimator) and an new AssetType "ModelLodAsset" to the engine.
How it works
-
Import a mesh / Create a new ModelAsset
-
After import it calls the MeshDecimator class and generate simplified meshes by given amount of lod levels.
-
For each LOD Level we got now an new a sset "ModelLodAsset" in the asset browser with the name of the mesh and a given suffix (TESTMESH_LOD1.sdmlod3d)
New Types
- ModeLodAsset (The asset for the lod model, hods the mesh data)
- ModelLodModel (Instance Holder for the Model)
New Properties:
- ModeLodAsset => List<Model> lods, float lodBias
- ModeAsset => Model SrcModel, int LodLevel, float Quality
- ModelComponent => List<Model> Lods (Hidden), float lodBias
New Libraries:
- MeshDecimator -> The remesh library
- MeshDataTool (MeshDataToolGPU, MeshDataToolStorage) -> A mesh data parser from gpu or storage
- MeshSurfaceTool - A simplified library to create triangle geometry
Next steps
[X] Thumbnail generation [ ] Project settings -> Default Bias Overall Threshold Multiplier [X] Project settings -> Default Lod Levels on import [X] New Modal for creation ModelLodAsset manualy (Without reimport the mesh) [ ] Attach the new lod models to the render pipeline and use the camera to control the distance and the right lod selection [X] Prevent to attache primitive or procedual genearted meshes [ ] Clean up [ ] Test scene [ ] Add support for bones [ ] Add support for colors [ ] Add support for multi uvs [ ] Documentation [ ] Next part: Range visibility detector

Sry dont know
So good news. Loding works stable. Some tweaks are neccesary, then we can start testing..
This could be changed to "Generate LOD Levels" so that it contains the letters LOD because they are easy to read and understand.
