some binary images are rendered as expected in 2D render windows, but the planes in the 3D render window remain black.
Example dataset: /home/jochen/temp/uchar-testimage.vti
it could be that this is because the pixeltype in this image is unsigned char. another test with a binary image with pixel type unsigned short showed up correctly.
This is due to a change from Mathias, which turned off the mapping of color (RGBA) scalars (unsigned chars) through the lookup table for the 3D texture. Anyhow, binary images are also (single channel) unsigned chars, and bypassed the LookupTable too.
-> Can be fixed by:
if( binary )
texture->MapColorS/calarsThroughLookupTableOn();
else
texture->MapColorScalarsThroughLookupTableOff();
Mathias, comment please, okay for you?
Solution looks fine to me! It is strange though that VTK interprets 1-component unsigned chars as color...
