DS development > 3D on two screens

#62742 - Vich - Mon Dec 05, 2005 10:03 am

As I understood, you can only use 3D on 1 of the two NDS screens, but Mariokart DS does 3D on 2 screens when introducing a race. That's when I started wondering about how to do that myself. I know it will cost a lot of frames, but can't you do it like this:

Suppose we have 3 buffers:
- Buffer A for the top screen (for 2D)
- B for the bottom screen (for 2D)
- C as a temporary buffer (for 3D)

Can you render in 3D mode to buffer C, then copy it to A, render another 3D frame to C and then copy it to B?

feel the magic renders 3d in 2 screens also, perhaps its only the librarys that we have that allows this?
