run method

  1. @override
Vector4 run(
  1. Float32List a,
  2. ShaderBindings bindings,
  3. Float32List out
)
override

Reads attributes — the vertex, as the engine laid it out — and writes a clip-space position plus varyings.

Implementation

@override
Vector4 run(Float32List a, ShaderBindings bindings, Float32List out) {
  out[0] = a[2];
  out[1] = a[3];
  return Vector4(a[0], a[1], 1.0, 1.0);
}
