Hi, I was making this post to ask if there are any other gpu's that render 3d graphics per scanline like the ds. As we all know, the ds doesn't use a framebuffer for its graphics display, it renders its polygons the way that sprites are rendered on retro consoles. You are limited on how many polygons you can render in a given frame, and fill rate isnt even a thing for the ds gpu since its done per scanline. So essentially, you can render a scene with all effects enabled, all at 60fps with the highest polycount the gpu supports. Is there any gpus in the past or after that render 3d models in this odd fasion?

Dreamcast's PowerVR2 had a bit similar render mode called "strip buffer".
instead of regular frame buffer it may use 2x screen-wide strips of tiles (at least 32pix height each), GPU will do render into one of them while another will be output to CRT display, then swap tile strips, and so on until whole frame will be rendered&displayed.

however, afaik no commercial games or homebrews uses this mode.
