Added support for rendering Arbitrary Output Variables (AOVs) for detailed outputs like beauty, albedo, normal, depth, and position.
Added new functions `render_aov` and `accumulate_aov` for AOV data management during rendering.
Added AOV rendering capabilities to the `SimpleLit` material with specific functions.
Changed the material system to include new function pointers for AOV rendering.
Changed the renderer to initialize and update AOV targets during the rendering process.
Changed the main rendering loop to handle AOVs and update render targets accordingly.
Fixed various minor issues, including function signature updates, variable name changes, and improved error handling for memory allocations.
Added a new enum `path_state` and a struct `path_output` in `Common.h` to manage path tracing states and outputs.
Added a new `simple_lit_render_loop` function in `SimpleLit.c` to handle rendering for simple lit materials, integrating light contributions and BSDF evaluations.
Changed the function signatures in `Light.h` to use `path_output` instead of `vec3s` for BSDF evaluations.
Changed the `evaluate_bsdf_directional` function in `LightEvaluation.h` to return `path_output` instead of `vec3s`.
Changed the `evaluate_bsdf_sky` function in `LightEvaluation.h` to return `path_output` and updated its implementation accordingly.
Changed the function signature of `evaluate_bsdf_const_sky` in `SkyLight.h` to return `path_output` and modified its implementation to match.
Removed several old BSDF-related functions in `Material.c` that are no longer needed due to the new structure.
Updated the `material_create` function in `Material.c` to accept the new render loop function pointer.
Updated the `path_trace` function in `PathTracing.c` to utilize the new `path_output` structure for managing light contributions and state transitions during path tracing.
Updated the `evaluate_bsdf_directional` function in `LightEvaluation.c` to return `path_output` and adjusted its internal logic to populate the output structure.
Updated the `evaluate_bsdf_const_sky` function in `SkyLight.c` to return `path_output` and modified its logic to handle light contributions correctly.
Updated the intensity of the sky light to `0.0f` during scene setup in `main.c`, effectively disabling it.
Added:
- Updated `.gitignore` to ignore the `[Bb]uild/` directory.
- Additional tasks added to the roadmap in `README.md` for light unit standardization and GPU backend support.
Changed:
- Removed line in `settings.json` that disabled error squiggles for C/C++ code.
- Modified `Triangle.h` to include `material_id` in `triangle_t` and reorganized properties.
- Reordered parameters in `triangle_collection_init` for clarity.
- Updated `shading_context_t` in `Material.h` and added size parameter to `material_create`.
- Streamlined initialization in `scene_init` and updated `scene_free` for proper resource management.
- Updated `window_create` in `Window.h` to accept a `render_job_t` parameter.
- Introduced `renderer_start` in `Renderer.c` to handle rendering jobs and optimized pixel rendering logic.
