refactor(gpu): Relocate effects to src/effects and streamline includes

2026-02-14T13:55:58Z

This refactoring improves the project's structure by decoupling visual effects from the core GPU module. All effect implementations have been moved from to a new top-level directory. Shared utilities like , , and have been consolidated into the parent directory. - **Motivation**: To create a clearer separation of concerns, making the codebase easier to navigate and maintain. This move treats effects as a distinct layer that depends on the core GPU module, rather than being embedded within it. - **Changes**: - Created new directory. - Moved all effect source files (, ) to . - Moved shared helpers (, , ) to . - Updated and to reflect the new file locations for all build targets. - Corrected all directives across the entire codebase (, , ) to point to the new paths. - Updated all markdown documentation ( files) to ensure file paths and architectural descriptions are accurate. - Fixed several compiler errors related to incorrect enum casting () that were exposed during cross-compilation for Windows. - **Verification**: - The entire project builds successfully for both native and Windows cross-compilation targets. - All 34 tests pass (Usage ctest [options]). - The --- Running Native Build & Tests --- Configuring with all options enabled (tests + tools)... -- -- Build Configuration: -- DEMO_SIZE_OPT: ON -- DEMO_STRIP_ALL: ON -- DEMO_FINAL_STRIP: OFF -- DEMO_STRIP_EXTERNAL_LIBS: OFF -- DEMO_BUILD_TESTS: ON -- DEMO_BUILD_TOOLS: ON -- DEMO_ENABLE_COVERAGE: OFF -- DEMO_ENABLE_DEBUG_LOGS: OFF -- DEMO_HEADLESS: OFF -- DEMO_WORKSPACE: main -- -- Loaded workspace: Main Demo -- Timeline: timeline.seq -- Music: pop_punk_drums.track -- Assets: assets.txt -- Using workspace: main -- Configuring done (0.0s) -- Generating done (0.1s) -- Build files have been written to: /Users/skal/demo/build Building all targets (demo, tests, and tools)...

Refactor: factorize common WGPU patterns into helper functions

2026-02-14T11:38:59Z

Add texture creation helpers (gpu_create_texture_2d, gpu_create_storage_texture_2d, gpu_create_mip_view) and extend BindGroupLayoutBuilder with uint_texture and storage_texture methods. Refactored files: - cnn_v2_effect.cc: Use texture helpers (~70% code reduction in create_textures) - rotating_cube_effect.cc: Use BindGroupLayoutBuilder and texture helpers - circle_mask_effect.cc: Use BindGroupBuilder Benefits: - Improved code readability - Reduced boilerplate for texture/bind group creation - Consistent patterns across effects Co-Authored-By: Claude Sonnet 4.5

CNN v2: bilinear mip-level sampling and UI improvements

2026-02-14T06:24:51Z

**CNN v2 Changes:** - Replace point sampling with bilinear interpolation for mip-level features - Add linear sampler (binding 6) to static features shader - Update CNNv2Effect, cnn_test, and HTML tool **HTML Tool UI:** - Move controls to floating bottom bar in central view - Consolidate video controls + Blend/Depth/Save PNG in single container - Increase left panel width: 300px → 315px (+5%) - Remove per-frame debug messages (visualization, rendering logs) **Technical:** - WGSL: textureSample() with linear_sampler vs textureLoad() - C++: Create WGPUSampler with Linear filtering - HTML: Change sampler from 'nearest' to 'linear' handoff(Claude): CNN v2 now uses bilinear mip-level sampling across all tools

CNN v2: Fix weight buffer offset bug

2026-02-13T23:27:53Z

Root cause: Binary format is [header:20B][layer_info:20B×N][weights]. Both cnn_test and CNNv2Effect uploaded entire file to weights_buffer, but shader reads weights_buffer[0] expecting first weight, not header. Fix: Skip header + layer_info when uploading to GPU buffer. - cnn_test.cc: Calculate weights_offset, upload only weights section - cnn_v2_effect.cc: Same fix for runtime effect Before: layer_0 output showed [R, uv_x, uv_y, black] (wrong channels) After: layer_0 output shows [R, G, B, D] (correct identity mapping) Tests: 34/36 passing (2 unrelated failures)

CNN v2: Alpha channel depth handling and layer visualization

2026-02-13T22:17:42Z

Training changes: - Changed p3 default depth from 0.0 to 1.0 (far plane semantics) - Extract depth from target alpha channel in both datasets - Consistent alpha-as-depth across training/validation Test tool enhancements (cnn_test): - Added load_depth_from_alpha() for R32Float depth texture - Fixed bind group layout for UnfilterableFloat sampling - Added --save-intermediates with per-channel grayscale composites - Each layer saved as 4x wide PNG (p0-p3 stacked horizontally) - Global layers_composite.png for vertical layer stack overview Investigation notes: - Static features p4-p7 ARE computed and bound correctly - Sin_20_y pattern visibility difference between tools under investigation - Binary weights timestamp (Feb 13 20:36) vs HTML tool (Feb 13 22:12) - Next: Update HTML tool with canonical binary weights handoff(Claude): HTML tool weights update pending - base64 encoded canonical weights ready in /tmp/weights_b64.txt for line 392 replacement.

CNN v2: Fix WebGPU validation error in uniform buffer alignment

2026-02-13T16:16:56Z

Fix two issues causing validation errors in test_demo: 1. Remove redundant pipeline creation without layout (static_pipeline_) 2. Change vec3 to 3× u32 fields in StaticFeatureParams struct WGSL vec3 aligns to 16 bytes (std140), making struct 32 bytes, while C++ struct was 16 bytes. Explicit fields ensure consistent layout.

CNN v2: Add TODO for flexible feature layout in binary format v3

2026-02-13T15:54:47Z

Document future enhancement for arbitrary feature vector layouts. Proposed feature descriptor in binary format v3: - Specify feature types, sources, and ordering - Enable runtime experimentation without shader recompilation - Examples: [R,G,B,dx,dy,uv_x,bias] or [mip1.r,mip2.g,laplacian,uv_x,sin20_x,bias] Added TODOs in: - CNN_V2_BINARY_FORMAT.md: Detailed proposal with struct layout - CNN_V2.md: Future extensions section - train_cnn_v2.py: compute_static_features() docstring - cnn_v2_static.wgsl: Shader header comment - cnn_v2_effect.cc: Version check comment Current limitation: Hardcoded [p0,p1,p2,p3,uv_x,uv_y,sin10_x,bias] layout. Co-Authored-By: Claude Sonnet 4.5

CNN v2: Add mip-level support to runtime effect

2026-02-13T15:48:02Z

Binary format v2 includes mip_level in header (20 bytes, was 16). Effect reads mip_level and passes to static features shader via uniform. Shader samples from correct mip texture based on mip_level. Changes: - export_cnn_v2_weights.py: Header v2 with mip_level field - cnn_v2_effect.h: Add StaticFeatureParams, mip_level member, params buffer - cnn_v2_effect.cc: Read mip_level from weights, create/bind params buffer, update per-frame - cnn_v2_static.wgsl: Accept params uniform, sample from selected mip level Binary format v2: - Header: 20 bytes (magic, version=2, num_layers, total_weights, mip_level) - Backward compatible: v1 weights load with mip_level=0 Co-Authored-By: Claude Sonnet 4.5

CNNv2Effect: Document per-layer kernel sizes support

2026-02-13T11:43:03Z

Updated comments to clarify that per-layer kernel sizes are supported. Code already handles this correctly via LayerInfo.kernel_size field. Changes: - cnn_v2_effect.h: Add comment about per-layer kernel sizes - cnn_v2_compute.wgsl: Clarify LayerParams provides per-layer config Co-Authored-By: Claude Sonnet 4.5

test_demo: Add beat-synchronized CNN post-processing with version selection

2026-02-12T14:10:17Z

- Add --cnn-version <1|2> flag to select between CNN v1 and v2 - Implement beat_phase modulation for dynamic blend in both CNN effects - Fix CNN v2 per-layer uniform buffer sharing (each layer needs own buffer) - Fix CNN v2 y-axis orientation to match render pass convention - Add Scene1Effect as base visual layer to test_demo timeline - Reorganize CNN v2 shaders into cnn_v2/ subdirectory - Update asset paths and documentation for new shader organization Co-Authored-By: Claude Sonnet 4.5
