Hi Lee -- I've been meaning to reply to this. I have only the utmost respect for Blender, which I've tackled a number of times. I mostly cut my teeth on POV-Ray (stills, but with loop constructs and frame saving), then VRML (+ XML = x3D), then some other formats, the key theme (for me) being simple spatial geometry, like the rhombic triacontahedron and like that. Here's there weirdo kind of stuff that gets me going: http://worldgame.blogspot.com/2008/12/coffee-shops-network.html (top one by me, bottom by Russell Towle) Actually, it hadn't really occurred to me to compare them, as I think of Sketchup as 3D etcha-sketch, whereas Blender is more about multiple objects with independent motion, or at least has that ability. But then I suppose Sketchup, programmed in Ruby or Python, does have this ability to run more of a movie, more than before. [1] I'm awed by this movie of Blender autogenerating whole cities, ala 'Inception', something I'd put beyond the bounds of even Sketchup Pro, but I could be mistaken (none of my current friends seem to have it). One possible advantage of SketchUp is the awesome on-line library of contributed buildings, other structures, which you can just download and snarf. My friend Trevor has been productive with Sketchup, in doing this retro-seeming movie of a never-realized concept in housing (looks like Uru, or that Island in Myst [2]). http://controlroom.blogspot.com/2009/11/4d-house.html John Driscoll picks up on a lot of the same themes (similar architectural memes): http://worldgame.blogspot.com/2010/05/architect.html As for myself, I came down in Visual Python, which is hard to beat for easy of use right out of the box: >>> from visual import * >>> sphere(radius=1) and bammo!, you've got an interactive window open in OpenGL. Arthur and I used to argue about whether it oughta be in the Standard Library. I took the conservative line and bellyached about bloat, but I secretly agree with him: VPython is one of the cardinal flagships, one of the major floats in the Python parade, worthy of its cheerleaders. Which isn't to say it couldn't do more. Will it record successive frames out to disk, at perhaps only a fraction of its rate in real time? I'm pretty sure not, yet that could be useful. Where there are frames, there are movies. > I tried getting in to SketchUp a few times but I never got > to the point where I could do anything very interesting. > > Also, it is not really free.

I'm thinking work out in Sketchup, get your feet wet, then move up to Blender maybe. Or take the VPython route. Or....
