Member Function Documentation

static vtkOpenGLTexture* vtkOpenGLTexture::New ( ) [static]

Create an object with Debug turned off, modified time initialized to zero, and reference counting on.

Reimplemented from vtkTexture.

virtual const char* vtkOpenGLTexture::GetClassName ( ) [virtual]

Reimplemented from vtkTexture.

static int vtkOpenGLTexture::IsTypeOf ( const char * name ) [static]

Return 1 if this class type 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 vtkTexture.

virtual int vtkOpenGLTexture::IsA ( const char * name ) [virtual]

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 vtkTexture.

static vtkOpenGLTexture* vtkOpenGLTexture::SafeDownCast ( vtkObject * o ) [static]

Reimplemented from vtkTexture.

virtual void vtkOpenGLTexture::PrintSelf	(	ostream &	os,
		vtkIndent	indent
	)			`[virtual]`

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 vtkTexture.

void vtkOpenGLTexture::Load ( vtkRenderer * ren ) [virtual]

Implement base class method.

Reimplemented from vtkTexture.

virtual void vtkOpenGLTexture::PostRender ( vtkRenderer * ) [virtual]

Cleans up after the texture rendering to restore the state of the graphics context.

Reimplemented from vtkTexture.

void vtkOpenGLTexture::ReleaseGraphicsResources ( vtkWindow * ) [virtual]

Release any graphics resources that are being consumed by this texture. The parameter window could be used to determine which graphic resources to release. Using the same texture object in multiple render windows is NOT currently supported.

Reimplemented from vtkTexture.

virtual long vtkOpenGLTexture::GetIndex ( ) [virtual]

Get the openGL texture name to which this texture is bound. This is available only if GL version >= 1.1
