- Frustum culling and distance culling using Compute Shader
- Optimize code structure to enable multiple Model Loading
- Replace the hardcode parameters with Uniform descriptors
- Cubemap
- Pipeline built and works well
- Still debugging the multi-layers image texture)
- Gui
- imgui library used
- works but haven’t merged
- LOD Culling:
- LOD0: 0 ~ 0.5 x (far_clip - near_clip)
- LOD1: 0.3 ~ 1.0 x (far_clip - near_clip)
- Overlapping area for the morphing
