25 hours	Fix: CNN v2 training - handle variable image sizes	skal
	Training script now resizes all images to fixed size before batching. Issue: RuntimeError when batching variable-sized images - Images had different dimensions (376x626 vs 344x361) - PyTorch DataLoader requires uniform tensor sizes for batching Solution: - Add --image-size parameter (default: 256) - Resize all images to target_size using LANCZOS interpolation - Preserves aspect ratio independent training Changes: - train_cnn_v2.py: ImagePairDataset now resizes to fixed dimensions - train_cnn_v2_full.sh: Added IMAGE_SIZE=256 configuration Tested: 8 image pairs, variable sizes → uniform 256×256 batches Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
43 hours	update cnn code	skal

2 days	fix: Complete auxiliary texture initialization fix	skal
	Root cause: After swapping init/resize order, effects with Renderer3D crashed because resize() called before init() tried to use uninitialized GPU resources. Changes: - Add guards in FlashCubeEffect::resize() and Hybrid3DEffect::resize() to check ctx_.device before calling renderer_.resize() - Remove lazy initialization remnants from CircleMaskEffect and CNNEffect - Register auxiliary textures directly in init() (width_/height_ already set) - Remove ensure_texture() methods and texture_initialized_ flags All 36 tests passing. Demo runs without crashes. Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
11 days	add mention of triplanar mapping	skal

11 days	fix(3d): Fix shader syntax error and duplicate declaration	skal
	- 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'.
11 days	fix(3d): Resolve shader validation error and tune shadows	skal
	- 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.
12 days	feat(gpu/assets): Fix tests, integrate bumpy 3D renderer and procedural assets	skal
	- 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.
12 days	feat: Add seamless bump mapping with procedural noise	skal
	- 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).
12 days	feat: Implement 3D system and procedural texture manager	skal
	- 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.
