Hello,
    We have seen the voglMPR2 example and we tried to disable the
blending to obtaine a cross between three perpendicular planes from
slides of a 3D Volume, but with the blending activate, we aren't able
to see the intersections between slides because these are
semitransparent.
Without Alpha Blending the images on the planes results to be rendered
with many artifacts such as black lines parallel to the best set of
sampling planes.(We work on a O2 that don't support texture3D and we
must replicate our bricks (with volumeMakeTransposed)).
How can we solve this problem ?

Thanks

Luca Gandolfo
