Is there any significant performance to be gained with 1D arrays instead of 2D arrays?
I mean, both in terms of looping and accessing items.
Doing...
var j = 0 # I don't do it 1D in a while, so this may be totally wrong. I hope you get my point.
for i in range( w*h ):
j = i/w
array[ i+j*w ] = ...
... instead of...
for j in range( h ):
for i in range( w ):
array[j][i] = ...
