VML
C++17 GLSL vector and matrix math library. Tweaked for best debug code gen.
Quick Usage
Introduce the GLSL types
using vec3 = vml::vector<float, 0, 1, 2>;
using mat3 = vml::matrix<float, vml::vector, vml::indices_pack<0, 1, 2>, vml::indices_pack<0, 1, 2>>;Compile shader code as C++
void mainImage( out vec4 fragColor, in vec2 fragCoord )
{
// Normalized pixel coordinates (from 0 to 1)
vec2 uv = fragCoord/iResolution.xy;
// Time varying pixel color
vec3 col = 0.5 + 0.5*cos(iTime+uv.xyx+vec3(0,2,4));
// Output to screen
fragColor = vec4(col,1.0);
}Debug!
About
Inspired by and borrowed major ideas from CxxSwizzle but mine is engineered for best possible debug code gen.
It includes a SDL based sample app that runs GLSL shaders in a software rasterizer. It can get decent framerates for simple/medium complexity shaders.
