init(bufferIndex:bufferOffset:bufferStride:stepFunction:stepRate:)
Creates a layout with the given buffer index, offset, stride, step function, and step rate.
Declaration
init(bufferIndex: Int, bufferOffset: Int = 0, bufferStride: Int, stepFunction: MTLVertexStepFunction = .perVertex, stepRate: Int = 1)Parameters
- bufferIndex:
The index of the buffer this layout refers to.
- bufferOffset:
The byte offset into the buffer for the first byte of this layout. Defaults to
0. - bufferStride:
The distance, in bytes, between consecutive vertices for attributes using this layout.
- stepFunction:
How the vertex shader steps through this layout’s data. Defaults to
.perVertex. - stepRate:
The number of instances that share the same per-instance data. Defaults to
1.
