The custom render() signature didn't match PostProcessEffect::render(),
so it was never called. The base class method was used instead, which
didn't update uniforms with the peak value.
Fixed by:
- Using correct override signature: render(pass, uniforms)
- Calling PostProcessEffect::render() to handle standard rendering
- Removed unused custom parameters (time, beat, peak_value, aspect_ratio)
- Added override keyword to update_bind_group()
Peak meter bar now displays correctly with audio_intensity.

Instead of duplicating the uniform structure definition, PeakMeterEffect
now uses ShaderComposer to include the common_uniforms snippet, ensuring
the struct definition always matches the canonical version.
Changes:
- Added shader_composer.h include
- Use ShaderComposer::Get().Compose() to prepend common_uniforms
- Changed 'Uniforms' → 'CommonUniforms' in shader
- Removed duplicate struct definition
This ensures consistency across all shaders and eliminates potential
drift between duplicate definitions.

The embedded shader in PeakMeterEffect was using the old uniform
structure with _pad0/_pad1 instead of the new beat_time/beat_phase
fields, causing the peak meter bar to not display correctly.
Updated to match CommonPostProcessUniforms structure:
- Removed _pad0, _pad1
- Added beat_time, beat_phase
- Moved _pad to end
Peak meter visualization now works correctly in test_demo.

BREAKING CHANGE: Timeline format now uses beats as default unit
## Core Changes
**Uniform Structure (32 bytes maintained):**
- Added `beat_time` (absolute beats for musical animation)
- Added `beat_phase` (fractional 0-1 for smooth oscillation)
- Renamed `beat` → `beat_phase`
- Kept `time` (physical seconds, tempo-independent)
**Seq Compiler:**
- Default: all numbers are beats (e.g., `5`, `16.5`)
- Explicit seconds: `2.5s` suffix
- Explicit beats: `5b` suffix (optional clarity)
**Runtime:**
- Effects receive both physical time and beat time
- Variable tempo affects audio only (visual uses physical time)
- Beat calculation from audio time: `beat_time = audio_time * BPM / 60`
## Migration
- Existing timelines: converted with explicit 's' suffix
- New content: use beat notation (musical alignment)
- Backward compatible via explicit notation
## Benefits
- Musical alignment: sequences sync to bars/beats
- BPM independence: timing preserved on BPM changes
- Shader capabilities: animate to musical time
- Clean separation: tempo scaling vs. visual rendering
## Testing
- Build: ✅ Complete
- Tests: ✅ 34/36 passing (94%)
- Demo: ✅ Ready
handoff(Claude): Beat-based timing system implemented. Variable tempo
only affects audio sample triggering. Visual effects use physical_time
(constant) and beat_time (musical). Shaders can now animate to beats.

Hardcoded vec2(1280.0f, 720.0f) → u.resolution
Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>

ctx_.device exists before init() but Renderer3D not initialized yet.
Changed guard from !ctx_.device to !initialized_ flag.
Set initialized_ = true after renderer_.init() in both effects.
All 36 tests pass. Demo runs without crash.
Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
|
|
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.

Simpler solution than lazy initialization: effects need correct
dimensions during init() to register auxiliary textures.
Changed initialization order in MainSequence:
- resize() sets width_/height_ FIRST
- init() can then use correct dimensions
Reverted lazy initialization complexity. One-line fix.
Tests: All 36 tests passing, demo runs without error

Prevents init/resize ordering bug and avoids unnecessary reallocation.
Changes:
- Auxiliary textures created on first use (compute/update_bind_group)
- Added ensure_texture() methods to defer registration until resize()
- Added early return in resize() if dimensions unchanged
- Removed texture registration from init() methods
Benefits:
- No reallocation on window resize if dimensions match
- Texture created with correct dimensions from start
- Memory saved if effect never renders
Tests: All 36 tests passing

Auxiliary textures were created during init() using default dimensions
(1280x720) before resize() was called with actual window size. This
caused compute shaders to receive uniforms with correct resolution but
render to wrong-sized textures.
Changes:
- Add MainSequence::resize_auxiliary_texture() to recreate textures
- Override resize() in CircleMaskEffect to resize circle_mask texture
- Override resize() in CNNEffect to resize captured_frame texture
- Bind groups are recreated with new texture views after resize
Tests: All 36 tests passing

Root cause: Uniform buffers created but not initialized before bind group
creation, causing undefined UV coordinates in circle_mask_compute.wgsl.
Changes:
- Add get_common_uniforms() helper to Effect base class
- Refactor render()/compute() signatures: 5 params → CommonPostProcessUniforms&
- Fix uninitialized uniforms in CircleMaskEffect and CNNEffect
- Update all 19 effect implementations and headers
- Fix WGSL syntax error in FlashEffect (u.audio_intensity → audio_intensity)
- Update test files (test_sequence.cc)
Benefits:
- Cleaner API: construct uniforms once per frame, reuse across effects
- More maintainable: CommonPostProcessUniforms changes need no call site updates
- Fixes UV coordinate bug in circle_mask_compute.wgsl
All 36 tests passing (100%)

Fixed buffer mapping callback mode mismatch causing Unknown status.
Changed from WaitAnyOnly+ProcessEvents to AllowProcessEvents+DevicePoll.
Readback now functional but CNN output incorrect (all white).
Issue isolated to tool-specific binding/uniform setup - CNNEffect
in demo works correctly.
Technical details:
- WGPUCallbackMode_WaitAnyOnly requires wgpuInstanceWaitAny
- Using wgpuInstanceProcessEvents with WaitAnyOnly never fires callback
- Fixed by using AllowProcessEvents mode + wgpuDevicePoll
- Removed debug output and platform warnings
Status: 36/36 tests pass, readback works, CNN shader issue remains.

Add BindGroupLayoutBuilder, BindGroupBuilder, RenderPipelineBuilder,
and SamplerCache to reduce repetitive WGPU code. Refactor
post_process_helper, cnn_effect, and rotating_cube_effect.
Changes:
- Bind group creation: 19 instances, 14→4 lines each
- Pipeline creation: 30-50→8 lines
- Sampler deduplication: 6 instances → cached
- Total boilerplate reduction: -122 lines across 3 files
Builder pattern prevents binding index errors and consolidates
platform-specific #ifdef in fewer locations. Binary size unchanged
(6.3M debug). Tests pass.

Two bugs causing black screen when CNN post-processing activated:
1. Framebuffer capture timing: Capture ran inside post-effect loop after
ping-pong swaps, causing layers 1+ to capture wrong buffer. Moved
capture before loop to copy framebuffer_a once before post-chain starts.
2. Missing uniforms update: CNNEffect never updated uniforms_ buffer,
leaving uniforms.resolution uninitialized (0,0). UV calculation
p.xy/uniforms.resolution produced NaN, causing all texture samples
to return black. Added uniforms update in update_bind_group().
Files modified:
- src/gpu/effect.cc: Capture before post-chain (lines 308-346)
- src/gpu/effects/cnn_effect.cc: Add uniforms update (lines 132-142)
- workspaces/main/shaders/cnn/cnn_layer.wgsl: Remove obsolete comment
- doc/CNN_DEBUG.md: Historical debugging doc
- CLAUDE.md: Reference CNN_DEBUG.md in historical section

CNNEffect's "original" input was black because FadeEffect (priority 1) ran
before CNNEffect (priority 1), fading the scene. Changed framebuffer capture
to use framebuffer_a (scene output) instead of current_input (post-chain).
Also add seq_compiler validation to detect post-process priority collisions
within and across concurrent sequences, preventing similar render order issues.
Updated stub_types.h WGPULoadOp enum values to match webgpu.h spec.

Implements automatic layer chaining and generic framebuffer capture API for
multi-layer neural network effects with proper original input preservation.
Key changes:
- Effect::needs_framebuffer_capture() - generic API for pre-render capture
- MainSequence: auto-capture to "captured_frame" auxiliary texture
- CNNEffect: multi-layer support via layer_index/total_layers params
- seq_compiler: expands "layers=N" to N chained effect instances
- Shader: @binding(4) original_input available to all layers
- Training: generates layer switches and original input binding
- Blend: mix(original, result, blend_amount) uses layer 0 input
Timeline syntax: CNNEffect layers=3 blend=0.7

- Total: ~5-8 KB (acceptable for 64k demo)
**Testing:**
- CNNEffect added to test_demo_effects.cc
- 36/36 tests passing (100%)
**Next Steps:**
- Training script (scripts/train_cnn.py) to generate real weights
- Multi-layer rendering with ping-pong textures
- Weight quantization for size optimization

Fixed validation error in test_3d_render:
- Uniform buffer was 64 bytes (mat4) but bind group expected 176 bytes (GlobalUniforms)
- Updated buffer creation to use sizeof(GlobalUniforms)
- Updated bind group entry size to match
- Updated update_buffers to write full GlobalUniforms struct
Error was:
Binding size 64 of Buffer with '' label is less than minimum 176
Root cause: VisualDebug uses same GlobalUniforms structure as main renderer
but was only allocating/binding mat4 portion.
Testing:
- All 34 tests passing (100%)
- test_3d_render runs without validation errors
- GPU procedural textures working (noise, perlin, grid)

- Fixed a persistent SEGFAULT in DemoEffectsTest, allowing all 33 tests to pass (100% test coverage).
- The fix involved addressing uniform buffer alignment, resource initialization order, and minor code adjustments in affected effects.
- Updated GEMINI.md to reflect the completion of Task #74 and set the focus on Task #75: WGSL Uniform Buffer Validation & Consolidation.
handoff(Gemini): Addressed the DemoEffectsTest crash and updated the project state. Next up is Task #75 for robust uniform buffer validation.
|
|
Related to Task #74. The dummy buffer used when effect_params is null
must be 32 bytes to match CommonPostProcessUniforms size, not 16 bytes.
Prevents potential validation errors when binding group expects 32-byte
uniform buffer at binding 3.
