[vtkusers] Color texture mapping

[Tim Hutton]

Hello!

I would like to map an RGB image onto a VTK object, is this possible?

I have created a vtkScalars object:

vtkScalars *scalars = vtkScalars::New();
scalars->SetNumberOfComponents(3);
scalars->SetNumberOfScalars(X*Y);

and filled it with the RGB values for my image, I would now like to use 
this as input to a vtkTexture
for mapping onto an object. When I try this I get only the first channel 
(red) being used, through a
rainbow lookup table.

Any pointers are much appreciated!

Thanks,

Tim.
