I've been playing around in blender from time to time... just to get my mind on something else. Now I have stumbled on to a work-in-progress tool that I like to shed a light on. It can be found in a blender branch from Nicholas Bishop (a blender developer), i.e. not an official build from the foundation. It's a sculpting tool called dynamic topology that hopefully makes it to the trunk in the near future. It works almost like the other excellent 3D tool called Sculptris. The tool lets you model/sculpt like you were working in clay. You can make areas more detailed or simplified as desired and the mesh will conform to the new shape, adding triangles or removing them on the fly.
I made this crude flat-shaded head in a couple of- hmm hours? I didn't keep track of time :-P You can see the different triangulation resolution on his forehead and shoulder compared to the more detailed areas around his eyes (the triangles have disappeared in size). Anyway... It's a pretty cool tool! If you are a blender user doing sculpting I would really recommend you to try it out!
I found a build at GraphicAll.org
Hope everyone had an excellent summer. Thanks for reading! =)
