Although Apple already started using compositing in 2002 with Quartz Extreme in Mac OS X 10.2, which also had X11 support.
- foobiekr 2y agoNextstep used compositing in the late 1980s.
- lproven 2y ago[[citation needed]] NeXTstep used Display Postscript. AFAIK this has no concept of 3D acceleration or anything akin to it, and was almost entirely unaccelerated.
- foobiekr 2y agocompositing 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).
