compositing has nothing to do with 3d acceleration. NeXT slabs and cubes did have a low-function blitter used to composite the main display.

- lproven 2y agoIn this direct context, I absolutely think it does and it's integral to the definition. What do you understand by "display compositing" that doesn't involve 3D hardware?
- foobiekr 2y agoWhat the hell does 3D hardware have to do with the block copies compositing window managers like MacOS are doing?
- foobiekr 2y agoEdit: this was the Turbo units, which did have a bus-assisted block copy. Before that, just well-tuned 68030 burst block copy - they rendered to backing store and did block copies with a special case of vram to vram block copies (used for window compositing).
