From a109983c194c45ad85f0e481232bc605c7cfd85b Mon Sep 17 00:00:00 2001 From: skal Date: Fri, 13 Feb 2026 08:34:24 +0100 Subject: Remediation: Implement shared common/shaders/ directory 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 --- common/shaders/compute/gen_grid.wgsl | 24 ++++++++++++++++++++++++ 1 file changed, 24 insertions(+) create mode 100644 common/shaders/compute/gen_grid.wgsl (limited to 'common/shaders/compute/gen_grid.wgsl') diff --git a/common/shaders/compute/gen_grid.wgsl b/common/shaders/compute/gen_grid.wgsl new file mode 100644 index 0000000..cc5e189 --- /dev/null +++ b/common/shaders/compute/gen_grid.wgsl @@ -0,0 +1,24 @@ +// GPU procedural grid pattern generator. +// Simple grid lines with configurable spacing and thickness. + +struct GridParams { + width: u32, + height: u32, + grid_size: u32, + thickness: u32, +} + +@group(0) @binding(0) var output_tex: texture_storage_2d; +@group(0) @binding(1) var params: GridParams; + +@compute @workgroup_size(8, 8, 1) +fn main(@builtin(global_invocation_id) id: vec3) { + if (id.x >= params.width || id.y >= params.height) { return; } + + let on_line = (id.x % params.grid_size) < params.thickness || + (id.y % params.grid_size) < params.thickness; + + let val = select(0.0, 1.0, on_line); + + textureStore(output_tex, id.xy, vec4(val, val, val, 1.0)); +} -- cgit v1.2.3
