Thanks everyone for the awesome ideas.
Im definitely checking out the RAD drive..
funny enough I do have a Shapeshifter unit somewhere in my garage. have to dig it out.
Definitely going to do some rendering. I was a big user of lightwave for fun when I had my Pentium 100. never tried it out on the Amiga.. also I always wanted to have a go at Real3d but back in the day I only had a 1meg a500.
have to find my pcmcia network card so I can hook up the a1200 to the net.
For some reason Ive purchased a Bliz 1240 card.. ha I'll probably upgrade it to a 060 when I get it. cant wait.
One thing you might have a go at - running Python scripts for big tool chains.
Two that come to mind are the Skeinforge and Printrun toolchains for turning .stl 3D objects into gcode ready for a 3D printer.
These ARE just python scripts with slow GUI, but with the right compiler, could perhaps be compiled into "real" Amiga versions. Gnu CC seems the most supported choice for that. They should run OK uncompiled on a Python interpreter (they prefer early versions of Python as found on Aminet).
Downloads for these are becoming quite scarce, but I did manange to find a set at;-
http://www.nextdayreprap.co.uk/reprap-downloads/An example of open source app developed from those ancestors would be Slic3r. Which is notoriously memory hungry in 32 bit versions, so my advice would be, steer clear of trying to convert it. A good comparison for it would be Cura from Ultimaker, which is NOT Open Source but is free to download from Ultimaker.
The latter two apps are only available for Windows, Mac, and Linux.
