My wife is a visual artist and she would like to try some 3d design program that would allow her to make some virtual reality. She has no experience in 3d design, but she is computer litterate and has done a lot of 2d computer design. My questions are, what applications might be interesting for her and how powerful computer do you need for 3D design? Is e.g. the eMac with its CRT screen good buy for this or do you need a better graphics card? We already have an iMac with 64mb graphics card and need a second computer anyway. Cheers!
