Detailed Description
A CC3VertexArray that manages the point sizes aspect of an array of point sprite vertices.
Member Function Documentation
| - (GLfloat) pointSizeAt: | (GLsizei) | index |
Returns the point size element at the specified index in the underlying vertex data.
The index refers to elements, not bytes. The implementation takes into consideration the elementStride and elementOffset properties to access the correct element.
If the releaseRedundantData method has been invoked and the underlying vertex data has been released, this method will raise an assertion exception.
| - (void) setPointSize: | (GLfloat) | aSize | |
| at: | (GLsizei) | index | |
Sets the point size element at the specified index in the underlying vertex data to the specified location value.
The index refers to elements, not bytes. The implementation takes into consideration the elementStride and elementOffset properties to access the correct element.
If the releaseRedundantData method has been invoked and the underlying vertex data has been released, this method will raise an assertion exception.
