Detailed Description
Member Function Documentation
| - (CC3Vector) normalAt: | (GLsizei) | index |
Returns the normal 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 createGLBuffer method has been invoked and the underlying vertex data has been released, this method will raise an assertion exception.
| - (void) setNormal: | (CC3Vector) | aNormal | |
| at: | (GLsizei) | index | |
Sets the normal element at the specified index in the underlying vertex data to the specified normal 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 createGLBuffer method has been invoked and the underlying vertex data has been released, this method will raise an assertion exception.
