Hi, I have a stack of color images with predefined colormap in matlab. Is it possible to get volume rendering while preserving the colormap? The only options I am getting are the pre set volume color maps.
Direct volume rendering of RGBA volumes is very uncommon, so we did not expose it on the GUI. You can enable it by typing a single line of code in the console.
Thank so much for the quick reply. I tried your suggestion and created an alpha stack and merged with the RGB stack. For the volume rendering I turned off the independent components. However, when I do the volume rendering it is still rendering it only on the scalar volume. Am I doing something wrong?
Thanks
Use GPU volume rendering and latest stable version. If does not work then maybe you could share your scene so that we can test it, too.
