- Does anyone have some very fast line drawings routines which use the
- CPU and not the blitter? I am programming some 3-d vector software for a
- high speed vector game/demo and the fastest way I have found to render
- lines is to draw them into FAST memory and then copy the lines into CHIP
- memory with the CPU. The fastest I can go though is about 60,000 lines
- per second (about 2 million pixels per second). I need to get a performance
- of at least 100,000 lines per second. I know I've got the power to get this
- thing running (68040 28MHz).
-
- I also may need a faster routine to copy the memory. Someone had
- mentioned using movem.l ??? Can anyone send me a routine which uses this?
- I have been using move.l with a dbf loop.
