Question: What is the purpose of this?

Let me just explain my own hopes before I give my critique. I do modeling and animation with blender, and I have a high end desktop that can not only render rather complex scenes and animations rather quickly, but runs blender much more smoothly than the N900 ever could. I don't really understand why you'd want to run Blender solely on the N900, just using it appears to crawl. A render would take forever, eat battery, and isn't this thing supposed to take and make phone calls? A cheaper desktop would do all of the work faster.

Which brings me to my point. Why not just use X11 forwarding? I doubt many people interested in using Blender don't already use it on a desktop connected to the internet.

If you're not familiar with X11 forwarding with ssh, it essentially allows one computer to run a program, but for another computer to simply display the output (similar to VNC, but just a single application, rather than the desktop). Here is a quick example I made using GIMP on the N900:

Running is through ssh would get rid of a lot of the library dependency issues (since blender would be running on a separated system, like my desktop powerhouse), and then the sole issue is the OpenGL wrapper.


Mind you, that isn't an easy task, but at least it's straightforward, compared to attempting to cross compile various libraries. The only downside I see this way, is the Original Poster can't fufill his want of using the Game Engine to develop for the n900 (although I doubt it would have worked out well even with the armel version).

TL;DR: Running a 3D graphics suite on a phone is silly, SSH is a better solution.
