DenisT, your method shows a really an nice boost compared to anything on the maxscript side
here are some benchmarks
ArrayDim: m=500 n=2000
Set(): 19.793s Mem: 118571040L
Cached Set(): 9.067s Mem: 118571040L
IndexFix: 8.518s Mem: 118570760L
DenisT’s: 0.209s Mem: 118570680L
Cached Set() simply caches Set() before entering the loop,
IndexFix eliminates index-1 substraction inside the loop
denisT strikes again!
Thank you very much, this is really helpful and instructive, too!
So you are copying from a jagged array (which can be created with MAXScript alone) to a 2D array.
Someone should preserve this snippet as a great example showing how you can leverage small pieces of C# within 3ds Max. Where would be a good place for this?
I’ll test it in my code asap.
BTW, this solution could be helpful for other purposes than mine, e.g. for quickly creating bitmaps?
