Quilts

Post by GCHarder »

Quilts

Hardware: ZX81+16K+8K Static RAM at 8192, uses WRX video mode.

Emulator: sx81+16K
This is a rather slow program so I've increased CPU speed to 400%.

This program builds "quilts" from various patches.

See the "Patches Folder" for patch descriptions.

For the purist I've also included a PSI Res version which just requires a
16K ZX81 with a standard ROM. As usual with PSI Res the plotting is pretty
ragged, it's best to use higher "Spacing Count" and lower "Polygon Count"
for this version.

Includes SHREB and Pseudo Hires versions. The PSI-Res version requires a standard ROM.

Uses the same logistic equation I used to use to generate random numbers, interesting program albeit a tad slow.

Hi Greg
are "row" and "column" swapped?

I set this: 7 columns, 2 rows

and got this: 7 rows, 2 columns

Actually, it's patches/row and patches/column. So 7 patches/column winds up as 7 rows.

It's a half-full or half-empty thing.

Nice quilt though.
