[vtkusers] Errors when using vtkTexture and vtkTextureMapToPlane

[Roger Blum]

Hi vtk users,

I am using bitmap textures to map on polygons (4 or more vertices) with Tcl. 
Although the textures seem to be mapped correctly I get the following error 
messages in the "vtkOutputWindow":

ERROR: In 
C:\Dashboards\Releases\rc-VTK-5-0-0-rc1\VTK\Filtering\vtkImageAlgorithm.cxx, 
line 123
vtkOpenGLTexture (08FF4518): Definition of Execute() method should be in 
subclass and you should really use the ExecuteData(vtkInformation 
*request,...) signature instead

ERROR: In 
C:\Dashboards\Releases\rc-VTK-5-0-0-rc1\VTK\Graphics\vtkTextureMapToPlane.cxx, 
line 85
vtkTextureMapToPlane (090D27D8): Not enough points for automatic plane 
mapping

Are these commonly known problems or is there something wrong with my vtk 
objects / pipeline?

Thanks in advance for your help,
Roger
