Corrects CMakeLists.txt to properly link test_sequence against GLFW and WGPU_LIBRARY. Ensures correct include paths for wgpu headers. Updates demo_effects.cc stub implementations. Finalizes test suite for sequence/effect system.
|
|
Refines tests for the sequence and effect system to focus on logic (init, start, end calls) rather than GPU output, as full GPU mocking is complex. Updates HOWTO.md to reflect this.
|
|
Fixes seq_compiler build for Windows cross-compilation. Moves common WebGPU compatibility shims to gpu.h. Applies project-wide coding style via clang-format. Verified on both macOS (native) and Windows (cross-compile).
|
|
Adds a 'seq_compiler' tool that converts a text-based timeline (assets/demo.seq) into a generated C++ file. This allows editing effect sequences and timing without modifying engine code. Replaces manual sequence creation with a generated 'LoadTimeline' function.
|
|
Refactors the rendering pipeline into a modular Sequence/Effect system. 'MainSequence' manages the final frame rendering and a list of 'Sequence' layers. 'Sequence' manages a timeline of 'Effect' objects (start/end/priority). Concrete effects (Heptagon, Particles) are moved to 'demo_effects.cc'. Updates main loop to pass beat and aspect ratio.
|
|
Adds a 'pack_source' CMake target that creates 'demo_all.tgz' using tar. This includes all source files, third-party dependencies (even those ignored by git), and submodules, ensuring a self-contained offline build package.
|
|
This adds a single CMake toggle to enable tools, tests, size optimizations, and code stripping, simplifying the development and verification workflow.
|
|
Updates gpu.cc to handle modern wgpu-native callback signatures (5 args) for macOS while maintaining Windows compatibility. Modifies audio.cc and CMakeLists.txt to ensure miniaudio encoding features are only stripped from the demo binary, not the tools (spectool/tests).

This commit ensures the 'final' assembly target is robust and works across all build configurations.
- Updated CMakeLists.txt to always include the asset_packer tool and use generator expressions for its path.
- Refactored main.cc to use the new drum assets and removed debug prints.
- The 'make final' command now correctly re-generates all assets and performs binary crunching.
|
|
Switched to using in to ensure CMake correctly resolves the tool path regardless of the build environment.
|
|
Renamed demo assets to 'demo_assets.txt' and created 'test_assets_list.txt' for AssetManagerTest to prevent interference.
- Updated CMakeLists.txt to generate separate headers for demo and test.
- Updated test_assets.cc to conditionally include the test-specific header.
- Incorporated gen_assets.sh into the 'final' target.
|
|
Introduces a 'final' target that automates the entire production pipeline: building the stripped binary, generating assets, and performing final compression (crunching).
- Updated CMakeLists.txt to define the 'final' target.
- Updated HOWTO.md with instructions for running 'cmake --build build --target final'.
|
|
This refactors the asset management system to be more efficient and cleaner.
- Moved common GetAsset/DropAsset logic to src/util/asset_manager.cc.
- Changed retrieval to use an array of records (AssetRecord) for O(1) lookups instead of a switch statement.
- Updated asset_packer to generate only raw data and the record array.
|
|
This commit makes the asset packer fully functional and adds an end-to-end test suite.
- Updated asset_packer.cc to read file contents and embed them as hex arrays.
- Added actual asset files (null.bin, test_asset.txt) for testing.
- Implemented src/tests/test_assets.cc to verify data integrity at runtime.
- Refactored CMakeLists.txt to handle generated file dependencies correctly.
|
|
Introduces a new asset management system to embed binary assets directly into the demo executable.
- Creates the directory for asset definition and an descriptor file.
- Implements to generate (with enum and declaration) and (with placeholder data).
- Integrates into CMake build, making depend on the generated asset files.
- Adds minimal integration in and documentation in .
This addresses Task 9 (compact in-line and off-line asset system).
|
|
Includes correct CMake configuration for GLFW native access, Objective-C++ compilation for the helper library on macOS, and applies clang-format to modified sources.
|
|
Adds a 'STRIP_ALL' mode to minimize binary size for the final build, and refines size optimization flags for macOS.
- **STRIP_ALL Mode**: Added a 'DEMO_STRIP_ALL' CMake option that defines 'STRIP_ALL'. In this mode, command-line parsing is bypassed (forcing fullscreen), debug labels/error callbacks are removed from WebGPU, and non-essential code (like iostream) is stripped.
- **macOS Optimizations**: Updated CMake to use '-dead_strip' instead of GNU '--gc-sections' on Apple platforms to resolve linker errors and improve dead code elimination.
- **Documentation**: Updated HOWTO.md to document the new 'Final / Strip Build' process and FETCH_DEPS.md for optimized wgpu-native build guidance.
- **Task 7 & 8**: Marks these tasks as completed in PROJECT_CONTEXT.md.
|
|
Replaces the complex wgpu-native submodule and manual platform-specific surface creation with a system-wide wgpu-native install (via Homebrew) and the glfw3webgpu helper library.
- Updates scripts/project_init.sh to fetch glfw3webgpu and ensure wgpu-native is installed.
- Refactors CMakeLists.txt to link against the system wgpu-native library.
- Simplifies src/platform.cc to use glfwCreateWindowWGPUSurface.
- Simplifies src/gpu/gpu.cc to use standard WebGPU headers.
- Updates FETCH_DEPS.md with new installation instructions.
- Updates PROJECT_CONTEXT.md with the new integration strategy.

This commit fulfills tasks 1 and 2, and adds a synchronized visual effect.
- **Fullscreen Mode**: Added '--fullscreen' command-line argument and dynamic toggling via 'F' key.
- **Keyboard Controls**: Implemented 'Esc' to exit and 'F' to toggle fullscreen in 'src/platform.cc'.
- **Synchronized Visuals**: Added a pulsating heptagon effect in 'src/gpu/gpu.cc' and 'src/gpu/shader.wgsl' that scales and changes color based on the real-time audio peak from the synth.
- **Refactor**: Abstracted platform-specific WebGPU surface creation into 'src/platform.cc' to keep 'src/gpu/gpu.cc' cross-platform.
- **Build System**: Corrected 'CMakeLists.txt' to properly link 'wgpu-native' and platform frameworks, and updated 'project_init.sh' to build the submodule.
- **Documentation**: Updated 'HOWTO.md' and 'PROJECT_CONTEXT.md' with new features and decisions.

Adds a new CTest unit test that performs a full, end-to-end verification of the 'spectool analyze' command.
The test programmatically generates a sine wave, saves it as a .wav file, executes the spectool executable as a subprocess to analyze the wave, and then verifies the integrity of the resulting .spec file.
This ensures the analysis pipeline (WAV decoding, windowing, FDCT, and file I/O) works correctly.
|
|
Leverages the built-in MP3 decoder in miniaudio to allow spectool's 'analyze' command to process .mp3 files in addition to .wav files.
Updates the tool's command-line help text and the project's HOWTO.md to reflect the new capability.
|
|
Adds a multi-voice, real-time audio synthesis engine that generates sound from spectrogram data using an Inverse Discrete Cosine Transform (IDCT).
Key features:
- A thread-safe, double-buffered system for dynamically updating spectrograms in real-time without interrupting audio playback.
- Core DSP components: FDCT, IDCT, and Hamming window functions.
- A simple sequencer in the main loop to demonstrate scripted audio events and dynamic updates.
- Unit tests for the new synth engine and Hamming window, integrated with CTest.
- A file documenting the build process, features, and how to run tests.
