Shaders and Materials

Morph uses typed shaders. Material fields are validated by shader definitions.

Define a Shader

TexturedQuad is shader {
  tint as Color;
  albedo as Texture2D;
  linearSampler as Sampler;

  Vertex method(position as Vector3, uv as Vector2) {
    pass uv;
    return MVP * position;
  }

  Fragment method(uv as Vector2) {
    return albedo.Sample(linearSampler, uv) * tint;
  }
}

---

Create Material from Shader

material is Material<TexturedQuad>();
material.tint is Color(1.0, 1.0, 1.0, 1.0);
material.albedo is Texture2D.Load("examples/assets/checker.png");
material.linearSampler is Sampler.Create();

Built-in Shader Data

• MVP is available in vertex stage for transforms
• pass sends values from vertex stage to fragment stage

Next Steps

• Textures and Samplers - Sampling textures correctly
• Low-Level Draw Commands - Submitting shader materials
