Detailed Description

A CC3VertexArray that manages the point sizes aspect of an array of point sprite vertices.

Method Documentation

- (GLfloat) pointSizeAt:

(GLuint)

index

Returns the point size element at the specified index in the underlying vertex content.

The index refers to vertices, not bytes. The implementation takes into consideration the vertexStride and elementOffset properties to access the correct element.

If the releaseRedundantContent method has been invoked and the underlying vertex content has been released, this method will raise an assertion exception.

- (void) setPointSize:		(GLfloat)	aSize
at:		(GLuint)	index

Sets the point size element at the specified index in the underlying vertex content, to the specified location value.

The index refers to vertices, not bytes. The implementation takes into consideration the vertexStride and elementOffset properties to access the correct element.

If the releaseRedundantContent method has been invoked and the underlying vertex content has been released, this method will raise an assertion exception.
