[QUOTE=tulamide] [QUOTE=Arsonide] [QUOTE=newt]Btw I think "S" has a built in function to rotate its arrays as well.[/QUOTE]
I thought something did, but I couldn't remember what. I think it was S.[/QUOTE]
Again, I'm sorry, but this is not quite right. The function indeed is called rotate array, but it shifts a 1-dimensional array to the right or to the left (aka the equivalent to moving, not angular rotation), so
rotated by 1 gets
or rotated by -1 gets
Ahh well thats ok. Thats the only type of array I can do in S :P
[QUOTE=tulamide]Also, when using any free rotional functions, wether from 's' or just sin/cos, you can't make sure you will always keep all values on the grid (because of the rounding, that needs to be applied), leading to overwriting or doubling values.
True, but once it gets to 90 degrees it should line back up, shouldn't it?
