loadpixels() performances
May 9th, 2005, 11:23am  
I didn't understand the need on changing the managing of the pixels array but from a simple test I did it seems very CPU-intensive. Is there any trick/suggestion to have high performance using it?

thanks, chr

just try to avoid using it.. it's not needed by P3D for instance (or rather, you should still include it but it doesn't do much) but with JAVA2D and OPENGL it'll make things slower.

And, for curiosity, do you think it will be much better with the 1.0 ? playing with pixels is very useful for my kind of experiments... thx guys

in P2D (currently unavailable) and P3D it will be very speedy. in OPENGL mode i think we can get it 2x as fast and in JAVA2D maybe a little faster.

i'd also like to provide an option for opengl that doesn't do the automatic bit-swapping and conversions, so that people who want to mess with pixels directly can do it without a loss of performance.
