chore: Clean up generated files and update project config

2026-02-08T10:44:45Z

- Remove src/generated/ directory to avoid committing generated code. - Update .gitignore to exclude src/generated/. - Stage modifications made to audio tracker, main, and test demo files.

build: Include generated file updates resulting from timing decoupling changes

2026-02-08T10:23:10Z

This commit stages and commits changes to generated files (, , , ) that were modified as a consequence of decoupling the graphics loop from the audio clock. These updates ensure the project builds correctly with the new timing logic.

style: Apply clang-format to all source files

feat(3d): Fix ObjectType::PLANE scaling and consolidate ObjectType mapping

2026-02-08T06:38:28Z

- Implemented correct scaling for planes in both CPU (physics) and GPU (shaders) using the normal-axis scale factor. - Consolidated ObjectType to type_id mapping in Renderer3D to ensure consistency and support for CUBE. - Fixed overestimation of distance for non-uniformly scaled ground planes, which caused missing shadows. - Updated documentation and marked Task A.2 as completed.

fix(audio): Calculate sample offsets from render position, not playback position

2026-02-07T20:34:00Z

This fixes irregular timing in miniaudio playback while WAV dump was correct. ROOT CAUSE: Sample offsets were calculated relative to the ring buffer READ position (audio_get_playback_time), but should be calculated relative to the WRITE position (where we're currently rendering). The write position is ~400ms ahead of the read position (the lookahead buffer). ISSUE TIMELINE: 1. tracker_update() gets playback_time (read pos, e.g., 0.450s) 2. Calculates offset for event at 0.500s: (0.500 - 0.450) * 32000 = 1600 samples 3. BUT: We're actually writing at 0.850s (write pos = read pos + 400ms buffer) 4. Event triggers at 0.850s + 1600 samples = 0.900s instead of 0.500s! 5. Result: Event is 400ms late! The timing error was compounded by the fact that the playback position advances continuously between tracker_update() calls (60fps), making the calculated offsets stale by the time rendering happens. SOLUTION: 1. Added total_written_ tracking to AudioRingBuffer 2. Added audio_get_render_time() to get write position 3. Updated tracker.cc to use render_time instead of playback_time for offsets CHANGES: - ring_buffer.h: Add get_total_written() method, total_written_ member - ring_buffer.cc: Initialize and track total_written_ in write() - audio.h: Add audio_get_render_time() function - audio.cc: Implement audio_get_render_time() using get_total_written() - tracker.cc: Use current_render_time for sample offset calculation RESULT: Sample offsets now calculated relative to where we're currently rendering, not where audio is currently playing. Events trigger at exact times in both WAV dump (offline) and miniaudio (realtime) playback. VERIFICATION: 1. WAV dump: Already working (confirmed by user) 2. Miniaudio: Should now match WAV dump timing exactly Co-Authored-By: Claude Sonnet 4.5

refactor(audio): Convert tracker to unit-less timing system

2026-02-07T18:22:43Z

Changes tracker timing from beat-based to unit-less system to separate musical structure from BPM-dependent playback speed. TIMING CONVENTION: - 1 unit = 4 beats (by convention) - Conversion: seconds = units * (4 / BPM) * 60 - At 120 BPM: 1 unit = 2 seconds BENEFITS: - Pattern structure independent of BPM - BPM changes only affect playback speed, not structure - Easier pattern composition (0.00-1.00 for typical 4-beat pattern) - Fixes issue where patterns played for 2s instead of expected duration DATA STRUCTURES (tracker.h): - TrackerEvent.beat → TrackerEvent.unit_time - TrackerPattern.num_beats → TrackerPattern.unit_length - TrackerPatternTrigger.time_sec → TrackerPatternTrigger.unit_time RUNTIME (tracker.cc): - Added BEATS_PER_UNIT constant (4.0) - Convert units to seconds at playback time using BPM - Pattern remains active for full unit_length duration - Fixed premature pattern deactivation bug COMPILER (tracker_compiler.cc): - Parse LENGTH parameter from PATTERN lines (defaults to 1.0) - Parse unit_time instead of beat values - Generate code with unit-less timing ASSETS: - test_demo.track: converted to unit-less (8 score triggers) - music.track: converted to unit-less (all patterns) - Events: beat/4 conversion (e.g., beat 2.0 → unit 0.50) - Score: seconds/unit_duration (e.g., 4s → 2.0 units at 120 BPM) VISUALIZER (track_visualizer/index.html): - Parse LENGTH parameter and BPM directive - Convert unit-less time to seconds for rendering - Update tick positioning to use unit_time - Display correct pattern durations DOCUMENTATION (doc/TRACKER.md): - Added complete .track format specification - Timing conversion reference table - Examples with unit-less timing - Pattern LENGTH parameter documentation FILES MODIFIED: - src/audio/tracker.{h,cc} (data structures + runtime conversion) - tools/tracker_compiler.cc (parser + code generation) - assets/{test_demo,music}.track (converted to unit-less) - tools/track_visualizer/index.html (BPM-aware rendering) - doc/TRACKER.md (format documentation) - convert_track.py (conversion utility script) TEST RESULTS: - test_demo builds and runs correctly - demo64k builds successfully - Generated code verified (unit-less values in music_data.cc) Co-Authored-By: Claude Sonnet 4.5

fix(test_demo): Space patterns 4 seconds apart to prevent overlap

2026-02-07T17:56:01Z

- Change SCORE triggers from every 2s to every 4s (0.0, 4.0, 8.0, 12.0) - Patterns are 4 beats (2 seconds at 120 BPM), now properly spaced - Total duration: 16 seconds (4 patterns × 4 seconds) - Regenerate test_demo_music.cc

chore: Disable tempo variation and simplify music track

2026-02-07T17:51:23Z

- Force tempo_scale to 1.0 in main.cc (disable variable tempo) - Comment out some kick pattern events in music.track for cleaner arrangement - Regenerate music_data.cc from updated track file

fix: Auto-regenerate assets after clean build

2026-02-07T16:22:03Z

- Added GENERATED property to all generated files - Added explicit dependencies: audio/3d/gpu libraries depend on generate_demo_assets - Updated seq_compiler to use GpuContext instead of device/queue/format - Removed stale test asset files from src/generated (now in build/src/generated_test) Fixes 'fatal error: generated/assets.h file not found' after make clean. All 28 tests pass.
