Hello list!
I have developed a software library for rendering 3D scenes.
It would be very cool if I could use the fb device so that X needn't be
running, freeing considerable resources for the application
Note that it is a _software_ renderer, I don't need access to 3D hardware
acceleration, just a means of copying/bliting frames to the screen as fast as
possible, and a double buffering facility
So what I need is an api allowing me to
- Set the screen resolution/colour depth. (16bit colour depth or better is
required)
- Allocate front and back buffers
- Copy scene to back buffer
- Swap buffers synced with vertical refresh
Does fbdev have the facilities I need?

Hmm.. cool! how you construct the 3D scenes?

Already part of fbdev.

You would probably want to look at SDL's fbdev backend.

Big question in ... 8 words!
Quick answer - custom 3D renderer :)

Good hint. I've just checked out SDL and it looks useful.
