Hi! I am working on a volumdata set of a heart. It is a scalarfield over a tetrahedral grid. I use the built in volumrender in OpenDX to visualize it.
A screencapture of the VPE in action looks like this: http://www.stud.ifi.uio.no/~rasmusb/hovedfag/dx/screen.jpg My question is, why are there red areas in the image? Since the opacety value for the red is 0, should'nt the red ares actually be black? To me it looks like the opacity table has no effect on the volumrender at all. Is this correct? Is the opacity table constant or something when using the volum render? The net and datafile for the example are available here: http://www.stud.ifi.uio.no/~rasmusb/hovedfag/dx/ -- Rasmus Bording [EMAIL PROTECTED] http://www.bording.no/rasmus "In the beginning the Universe was created.
