Hello list!

I have developed a software library for rendering 3D scenes.

Hmm.. cool! how you construct the 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)

Already part of fbdev.

- Allocate front and back buffers

- Copy scene to back buffer

- Swap buffers synced with vertical refresh

Does fbdev have the facilities I need?

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