Thank you so much for this. This will probably help me get to grips with volume rendering. I am new to the techniques and concept related to volume rendering so I appreciate resources like this. The course notes are huge, so thank you for that as well.
BTW, I am able to open and read the paper you wrote, but I am not able to download it and print it. It is a short paper so it does not matter that much, but I thought you might want to know. Maybe I can download it if I am on my university’s network. Will update after I have tested that.
