Getting started

Minimal pipeline

// Includes
#include <screenConstants>
#include "shader/customInclude.lum"
 
// Pipeline flow
Input -> VertexPass: Vector3 vertexPosition;
VertexPass -> FragmentPass: Vector2 fragUV;
 
// Vertex stage
VertexPass()
{
    Vector4 clip = Vector4(vertexPosition, 1.0);
    pixelPosition = clip;
    fragUV = vertexPosition.xy * 0.5 + 0.5;
}
 
// Fragment stage
FragmentPass()
{
    Vector4 finalColor = Vector4(fragUV.x, fragUV.y, 0.0, 1.0);
    pixelColor = finalColor;
}

Build outputs

The compiler emits:

• GLSL for vertex and fragment stages.
• A compiled artifact Sparkle reads to bind your pipeline (see Compiled artifact format).
