Detailed Description

The VertexArrayObject class uses, or emulates, vertex array objects.

These are extremely useful for setup/tear down of vertex attributes, and can offer significant performance benefits when the hardware supports them.

It should be noted that this object is very lightweight, and it assumes the objects being used are correctly set up. Even without support for VAOs this class caches the array locations, types, etc and avoids repeated look ups. It it bound to a single ShaderProgram object.

Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.
