Among other things today, I downloaded and installed ac3d, a 3D modeling program, for Linux. The installation, if you can call it that, was very simple. All I had to do was tar -xzvf the .tgz file and then switch to the new directory to run ac3d. My first impressions of the program were that it had a nice, simple interface (although the aesthetics seem to be lacking) and easily accessible tools. After fiddling around with it for a while, I started to like what I was using. Overall, the feel of the whole program was very smooth and simple. I am by no means a 3D modeling expert, but I feel this could be a very useful program in the real world. Sadly, the demo version only lasts 14 days and the real program costs about $60, so I don’t see this application in my future, but perhaps it could be in yours! Try it out.
