Declared in CC3VertexArrays.h

Overview

A CC3VertexArray that manages the tangent or bitangent aspect of an array of vertices.

Tasks

Instance Methods

setTangent:at:

Sets the tangent element at the specified index in the underlying vertex content to the specified tangent value.

- (void)setTangent:(CC3Vector)aTangent at:(GLuint)index

Discussion

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.

Declared In

tangentAt:

Returns the tangent element at the specified index in the underlying vertex content.

- (CC3Vector)tangentAt:(GLuint)index

Discussion

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