[vtkusers] texture map to cube

[Dean Inglis]

I am trying to texture map a set of 6 face labels
to a cube.  So far I am just trying to map 4 of
the faces with +/- coordinate face labels. The input
image looks like this:

---------------------
| -X | -Y | +X | +Y |
---------------------

The unsuccessful pipeline is:

package require vtk
package require vtkinteraction

vtkCubeSource cube
cube SetBounds -1 1 -1 1 -1 1

vtkTextureMapToPlane tmap
#vtkTextureMapToCylinder tmap
tmap SetInput [cube GetOutput]
#tmap AutomaticPlaneGenerationOn

vtkPolyDataMapper pmap
pmap SetInput [tmap GetOutput]

vtkPNGReader reader
reader SetFileName "testwrap.png"

vtkTexture texture
texture SetQualityTo32Bit
texture InterpolateOn
#texture RepeatOn
texture RepeatOff
texture SetInput [reader GetOutput]

vtkActor tact
tact SetMapper pmap
tact SetTexture texture


# Create graphics stuff
#
vtkRenderer ren1
vtkRenderWindow renWin
    renWin AddRenderer ren1
vtkRenderWindowInteractor iren
    iren SetRenderWindow renWin

# Add the actors to the renderer, set the background and size
ren1 AddActor tact

ren1 ResetCameraClippingRange
ren1 SetBackground 0 .5 .4

renWin SetSize 800 800
iren Initialize

# render the image
#
iren AddObserver UserEvent {wm deiconify .vtkInteract}

# prevent the tk window from showing up then start the event loop
wm withdraw .


any hints?  thanks,
Dean
