It's still crappy Intel graphics graphics. You absolutely should expect crappy results with volume on any Intel graphics system. I have said this several times now, but it seems the message hasn't sunk in yet. So... I'll say it again. IT'S POINTLESS TRYING TO DO VOLUME RENDERING ON INTEL GRAPHICS HARDWARE, THEY ARE TOTALLY AND UTTERLY INCAPABLE OF HANDLING IT. >I ran the testing code and there is no any error message on console, but the >display image is not correct.

Do you think this problem is also related to the hardware? What did I say in my previous email? 1) It has nothing to do with mipmapping because mipmapping isn't used for volume rendering, 2) Intel graphics hardware and driver are woefully inadequate. I know this isn't the message you want to hear, but you'll get the same message every time you try and attempt to volume rendering with Intel hardware. If you can't take this on board or other things I suggest, then how much point is there in me even trying to reply to your support posts?
