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.

Reimplemented from vtkObject.

int vtkOpenGLVertexBufferObjectGroup::GetNumberOfComponents ( const char *  attribute)

Returns the number of components for this attribute zero if the attribute does not exist.

int vtkOpenGLVertexBufferObjectGroup::GetNumberOfTuples ( const char *  attribute)

Returns the number of tuples for this attribute zero if the attribute does not exist.

void vtkOpenGLVertexBufferObjectGroup::ReleaseGraphicsResources ( vtkWindow )

Release any graphics resources that are being consumed by this mapper.

The parameter window could be used to determine which graphic resources to release.

vtkOpenGLVertexBufferObject* vtkOpenGLVertexBufferObjectGroup::GetVBO ( const char *  attribute)

Returns the VBO for an attribute, NULL if it is not present.

void vtkOpenGLVertexBufferObjectGroup::AddAllAttributesToVAO ( vtkShaderProgram program,
vtkOpenGLVertexArrayObject vao 
)

Attach all VBOs to their attributes.

void vtkOpenGLVertexBufferObjectGroup::CacheDataArray ( const char *  attribute,
vtkDataArray da,
vtkOpenGLVertexBufferObjectCache cache,
int  destType 
)

Set the data array for an attribute in the VBO Group registers the data array until build is called once this is called a valid VBO will exist.

void vtkOpenGLVertexBufferObjectGroup::CacheDataArray ( const char *  attribute,
vtkDataArray da,
vtkViewport vp,
int  destType 
)
void vtkOpenGLVertexBufferObjectGroup::AppendDataArray ( const char *  attribute,
vtkDataArray da,
int  destType 
)

Append a data array for an attribute in the VBO Group registers the data array until build is called.

void vtkOpenGLVertexBufferObjectGroup::BuildAllVBOs ( vtkOpenGLVertexBufferObjectCache )

using the data arays in this group build all the VBOs, once this has been called the reference to the data arrays will be freed.

void vtkOpenGLVertexBufferObjectGroup::BuildAllVBOs ( vtkViewport )
void vtkOpenGLVertexBufferObjectGroup::ClearAllDataArrays ( )
