Textures: Guidance on Texture Compression Workflow for 3D Tiles (glTF 2.0) #254
Description
Current Behavior
Best practices for compressing textures in 3D Tiles using glTF 2.0 are not yet fully documented. There are several promising approaches for generating GPU-friendly compressed formats (like KTX2) that could be explored and integrated into 3D Tiles workflows.
Proposed Guidance
- Recommended workflow for preparing and compressing textures before inclusion in 3D Tiles / glTF 2.0 assets.
- Suggested tools for texture compression and guidance on integrating them efficiently into pipelines.
- Best practices to maintain texture quality, performance, and file size optimization.
- Considerations for incorporating compressed textures into automated 3D Tiles generation workflows.
Use Cases
- Reducing 3D Tiles asset size for runtime delivery
- Streamlining preprocessing of textures in automated 3D Tiles pipelines
