Renderable::SetVertexAttributeArray

Defined in: C4Renderable.h

Sets the offset and size of a vertex attribute array.

Prototype

void SetVertexAttributeArray(int32 index, uint32 offset, int32 count);

Parameters

`index`	The index of the vertex attribute array.
`offset`	The offset of the first element of the attribute array, in bytes.
`count`	The number of 32-bit components composing the attribute.

Description

The SetVertexAttributeArray function sets the offset within the vertex buffer to the first element of the vertex attribute array specified by the index parameter. The offset parameter should typically be set to the cumulative size of the vertex attributes preceding the attribute having the index given by the index parameter for a single vertex. The count parameter specifies the number of 32-bit floating-point components used by the attribute, or the number of 32-bit words in the case that the attribute is composed of integer data.
