- 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.
|
|
- 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.
- Implemented hard/soft shadows from a fixed directional light.
- Updated GlobalUniforms struct with proper packing/padding for WebGPU compatibility.
- Captured 'GPU BVH & Shadows' task in PROJECT_CONTEXT.md for future optimization.

|
- Added 'src/3d/visual_debug.h/cc' to implement wireframe rendering.
- 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.

- Fixed test_sequence by restoring MainSequence::init_test for mocking.
- Corrected CMakeLists.txt dependencies and source groupings to prevent duplicate symbols.
- standardizing Effect constructor signature for seq_compiler compatibility.
- Implemented Hybrid3DEffect using bumpy Renderer3D and procedural NOISE_TEX.
- Updated MainSequence to support depth buffer for 3D elements.
- Formatted all source files with clang-format.
|
|
- Added depth buffer support to MainSequence.
- Implemented Hybrid3DEffect for the main timeline.
- Fixed effect initialization order in MainSequence.
- Ensured depth-stencil compatibility for all scene effects.
- Updated demo sequence with 3D elements and post-processing.
|
|
- Updated asset_packer to correctly parse PROC(...) syntax using regex, handling nested commas.
- Implemented runtime dispatch in AssetManager for procedural generation with dynamic memory management.
- Added procedural generator functions (noise, grid, periodic).
- Added comprehensive tests for procedural asset lifecycle (generation, caching, invalidation).
- Fixed C++ string literal escaping in asset_packer.
|
|
- Replaced white noise with smooth value-like noise.
- Implemented periodic texture generation (seam blending).
- Integrated bump mapping into Renderer3D using finite difference of displaced SDF.
- Updated test_3d_render with noise texture and multiple SDF shapes (Box, Sphere, Torus).
|
|
- Added SDF logic for Sphere, Box, and Torus in WGSL.
- Implemented hybrid normal calculation (analytical for sphere, numerical fallback).
- Updated Renderer3D to dispatch object types to shader.
- Updated test_3d_render to display mixed SDF shapes (Sphere, Torus, Box).
- Added BOX to ObjectType enum.
|
|
- Extended mini_math.h with mat4 multiplication and affine transforms.
- Implemented TextureManager for runtime procedural texture generation and GPU upload.
- Added 3D system components: Camera, Object, Scene, and Renderer3D.
- Created test_3d_render mini-demo for interactive 3D verification.
- Fixed WebGPU validation errors regarding depthSlice and unimplemented WaitAny.
