u/pavel

Wanted to make a 3d lattice with perspective
u/joeytwiddle

Didn't you already achieve that in d/13728 ?
u/pavel

Different method of generating a 3d lattice that rotates. Why is rotation so simple in this form?

u/keithclark

Also fixes some glitches in the original
u/keithclark

swap ,k=r>>8,k for ,r>>=8,r to save a byte (97)
u/keithclark

also r=900/(4-(t+j/9)%4) => r=j/(4-(t+j/9)%4) (94)
