Type alias AttributeOptions

Type declaration

• arrayBuffer: ArrayType

• format: GPUVertexFormat

• itemCount: number

  The number of items in the attribute. For example, given a vertex attribute this would the number of vertices stored in the buffer.

  e.g.

  const triangleVertices = new Float32Array([
   -1.0, -1.0, 1.0, -1.0, 1.0, 1.0,
  ]);
  
  const posAttribute = new Attribute({
   // other stuff
   format: "float32x2",
   itemCount: triangleVertices.length / 2,
  });
  Copy

  would have an itemCount of 3, because three 2D vertices are contained in the buffer.

• itemSize: number

  The number of components in each item of the attribute e.g.

  @location(0) pos: vec3<f32>
  Copy

  would have an itemSize of 3.

• Optional label?: string

• shaderLocation: number

  The value of the location directive of the attribute in the shader e.g.

  @location(0) pos: vec3<f32>
  Copy

  would have a shaderLocation of 0.
