refactor: move common/shaders/ to src/shaders/

2026-02-28T08:08:57Z

Relocates shared WGSL shaders under src/ where all source code lives, eliminating the top-level common/ directory. - Update asset references in workspaces/main/assets.txt and workspaces/test/assets.txt - Update docs: PROJECT_CONTEXT.md, ARCHITECTURE.md, WORKSPACE_SYSTEM.md, SHADER_REUSE_INVESTIGATION.md Co-Authored-By: Claude Sonnet 4.6

replace wgsl type: vec4 -> vec4f ..

fix(shaders): deduplicate VertexOutput/vs_main via render/fullscreen_uv_vs snippet

2026-02-27T23:51:27Z

- Fix vs_main return type (VertexOutput, not vec4) - Fix #include paths in passthrough, gaussian_blur, heptagon, combined_postprocess - ShaderComposer: assert + suggest correct path on missing #include (non-STRIP_ALL) - VerifyIncludes: upgrade WARNING to ERROR + assert, add "did you mean?" hint Co-Authored-By: Claude Sonnet 4.6

refactor(wgsl): Use vec*f alias for vector types

2026-02-21T08:50:09Z

Replaces all instances of `vec` with the more concise `vec*f` alias (e.g., `vec3f`) across all `.wgsl` shaders. This improves readability and aligns with common graphics programming conventions. Also adds a new coding style rule to `doc/CODING_STYLE.md` to enforce this standard going forward. Finally, this commit fixes a build error in `test_effect_base.cc` by replacing a call to the non-existent `wgpuDeviceTick` with `wgpuDevicePoll`, which resolves the test failure.

split raymarching.wgsl in two: with id, or without id.

feat(gpu): add two-pass raymarching infrastructure

2026-02-14T18:21:05Z

Add RayMarchResult struct and functions for deferred SDF rendering: - rayMarchWithID() tracks object ID and distance_max - reconstructPosition(), normalWithID(), shadowWithStoredDistance() - Pass 1: store geometry data, Pass 2: reuse for shading Add WGSL style rule: prefer return values over pointers for small structs (≤16 bytes).

refactor(wgsl): modularize common shader functions

2026-02-14T14:13:09Z

Extracted common WGSL functions into separate files in `common/shaders/` to improve reusability and maintainability. - Created `common/shaders/render/fullscreen_vs.wgsl` for a reusable fullscreen vertex shader. - Created `common/shaders/math/color.wgsl` for color conversion and tone mapping functions. - Created `common/shaders/math/utils.wgsl` for general math utilities. - Created `common/shaders/render/raymarching.wgsl` for SDF raymarching logic. - Updated multiple shaders to use these new common snippets via `#include`. - Fixed the shader asset validation test to correctly handle shaders that include the common vertex shader. This refactoring makes the shader code more modular and easier to manage.

Remediation: Implement shared common/shaders/ directory

2026-02-13T07:34:24Z

Eliminates 36 duplicate shader files across workspaces. Structure: - common/shaders/{math,render,compute}/ - Shared utilities (20 files) - workspaces/*/shaders/ - Workspace-specific only Changes: - Created common/shaders/ with math, render, compute subdirectories - Moved 20 common shaders from workspaces to common/ - Removed duplicates from test workspace - Updated assets.txt: ../../common/shaders/ references - Enhanced asset_packer.cc: filesystem path normalization for ../ resolution Implementation: Option 1 from SHADER_REUSE_INVESTIGATION.md - Single source of truth for common code - Workspace references via relative paths - Path normalization in asset packer handoff(Claude): Common shader directory implemented
