Detailed Description

manage vertex buffer objects shared within a context

This class allows mappers to share VBOs. Specifically it is used by the V..B..O..Group to see if a VBO already exists for a given vtkDataArray.

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.

Reimplemented from vtkObjectBase.

◆ PrintSelf()

void vtkOpenGLVertexBufferObjectCache::PrintSelf ( ostream &  os,
vtkIndent  indent 
)
overridevirtual

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.

Reimplemented from vtkObject.

◆ GetVBO()

vtkOpenGLVertexBufferObject* vtkOpenGLVertexBufferObjectCache::GetVBO ( vtkDataArray array,
int  destType 
)

Returns the vertex buffer object which holds the data array's data.

If such a VBO does not exist a new empty VBO will be created you need to append to. The return value has been registered, you are responsible for deleting it. The data array pointers are also registered.

◆ RemoveVBO()

void vtkOpenGLVertexBufferObjectCache::RemoveVBO ( vtkOpenGLVertexBufferObject vbo)

Removes all references to a given vertex buffer object.
