Write in Ruby
Declare uniforms and express fragment logic with Ruby blocks.
Ruby Like Shading Language
Ruby syntax. GPU reach.
Write shaders with Ruby constructs. RLSL infers types and emits GLSL, WGSL, MSL, or C.
gem install rlsl
INPUT · RUBYfragment { ... }
→GLSL · WGSLMSL · C
Author once. Choose the output.
Keep shader logic with the Ruby app, then select a target at the call site.
Infer shader types
Use vector operations and inferred variable types.
Target four outputs
Generate GLSL, WGSL, Metal Shading Language, or C source.
A small first step
Start with one example.
Install the gem, then follow the project guide for platform requirements and the full API.
require "rlsl"
shader = RLSL.to_wgsl(:pulse) do
uniforms { float :time }
fragment do |coord, resolution, u|
uv = coord / resolution
wave = sin(u.time + uv.x * 6.28)
vec3(uv.x, uv.y, wave * 0.5 + 0.5)
end
end
