Member Function Documentation

vtkOpenGLTexture* vtkOpenGLTexture::New (    )  [static]

Instantiate object with no start, end, or progress methods. Reimplemented from vtkTexture.

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

Return the class name as a string. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkTexture.

int vtkOpenGLTexture::IsTypeOf (  const char *    type )  [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 *    type )  [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.

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

Will cast the supplied object to vtkObject* is this is a safe operation (i.e., a safe downcast); otherwise NULL is returned. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkTexture.

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

Implement base class method. 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.

unsigned char* vtkOpenGLTexture::ResampleToPowerOfTwo (  int &    xsize, int &    ysize, unsigned char *    dptr, int    bpp )  [protected]
