- Restored vertical lighting and original soft shadow loop (k=8, t+=h).
- Maintained instance-based skip_idx for generic self-shadowing prevention.
- Confirmed map_scene correctly skips the floor, allowing other objects to cast shadows on it.
|
|

|
|
- Reverted test_3d_render to use the global 'noise' texture for floating objects, restoring their bump mapping.
- Implemented a procedural grid directly in the fragment shader for rasterized objects (floor).
- Inverted the grid color scheme (black lines on a lighter background) as requested.
- This ensures accurate object bump mapping and clear shadow visibility on the floor without requiring multiple texture bindings.
|
|
- Replaced invalid 'i++' with 'i = i + 1' in the shader's calc_shadow function loop.
- This resolves the shader parsing error and allows the 3D renderer test to run successfully on all platforms.
|
|
- Modified 'test_3d_render' to generate and use a procedural 'grid' texture for the floor.
- Updated fragment shader to sample the texture for rasterized objects, adding a grid pattern to the floor.
- This provides visual detail and contrast, making raymarched shadows much easier to observe and verify.
|
|
- Removed duplicate 'light_dir' declaration in the shader.
- Fixed a syntax error (duplicate closing raw string delimiter) that caused shader compilation failure.
- Verified all targets build and run correctly with 'check_all.sh'.
|
|
- Fixed 'redefinition of light_dir' shader validation error by centralizing the light definition at the top of fs_main.
- Further brightened the floor in 'test_3d_render' for better shadow contrast.
- Reduced shadow bias and made the light more vertical to ensure shadows are clearly visible on all surfaces.
|
|
- Part 1: Unified shadow calculation in fragment shader for both SDF and rasterized objects.
- Part 2: Added 'model_inverse_transpose' to ObjectData to correctly transform normals for non-uniformly scaled objects.
- Part 3: Brightened the floor in 'test_3d_render' to make shadows visible.
- Verified correct lighting and shadows on the non-uniformly scaled floor.
|
|
- Implemented full support for non-uniform scaling by calculating and passing the 'model_inverse_transpose' matrix to the shader for correct normal transformation.
- Added 'transpose()' and 'inverse()' methods to the 'mat4' class in 'mini_math.h'.
- Refactored the shader to use the new matrix for lighting rasterized objects.
- Updated the test scene to use a rasterized floor (CUBE) instead of an SDF one, ensuring it receives correct lighting and shadows even with non-uniform scale.
|
|
- Refactored the fragment shader to calculate raymarched shadows for all fragments, not just SDF objects.
- This enables rasterized objects (like the floor) to receive shadows from SDF objects, fixing the missing shadows in the test scene.
- This serves as a proof-of-concept for a unified lighting pipeline.
|
|
- Changed the floor object in 'test_3d_render' from SDF BOX to rasterized CUBE.
- This prevents the non-uniform scale of the floor from breaking the scene-wide SDF query used for shadow calculations.
- The lighting and shadows now render correctly in the more complex test scene.
|
|
- Updated 'src/tests/test_3d_render.cc' to populate the scene with a large floor and 30 randomly placed objects (spheres, boxes, tori).
- This provides a more complex environment to verify the new shadow mapping implementation.
|
|
- Updated Renderer3D shader to include 'map_scene' and 'calc_shadow' functions.
- Shader now iterates over all objects (up to kMaxObjects) to evaluate the scene SDF globally.

|
|

- Integrated VisualDebug into Renderer3D with a static global toggle.
- Added '--debug' command-line option to 'demo64k' and 'test_3d_render' to enable wireframes.
- Updated 'src/gpu/effects/hybrid_3d_effect.h' to expose the debug setter (reverted later as static method used).
- Ensured full cross-platform compatibility (native and Windows) for the new debug module.
- All code guarded by STRIP_ALL for final release.
|
|
- Added preprocessor definitions for 'WGPUOptionalBool_True' and 'WGPUOptionalBool_False' to ensure successful cross-compilation against the older wgpu-native headers used for the Windows build.
- This resolves the build failures in the Windows CI/check script.
|
|
- Task A: Centralized all generated code (assets, timeline) into a single directory to create a single source of truth.

|
|
