invariant

invariant(data): Decorated<Vec4f, [Builtin<"position">, Invariant]>

Defined in: packages/typegpu/src/data/attributes.ts:305

Marks a position built-in output value as invariant in vertex shaders. If the data and control flow match for two position outputs in different entry points, then the result values are guaranteed to be the same.

Must only be applied to the position built-in value.

Parameters

data

Decorated<Vec4f, [Builtin<"position">]>

The position built-in data-type to mark as invariant.

Returns

Decorated<Vec4f, [Builtin<"position">, Invariant]>

Example

const VertexOutput = {
  pos: d.invariant(d.builtin.position),
};
