What I just thought of (totally off topic): Does perhaps GL offer some way of doing vector math like this? (Add 2 vectors and calculate it's length.)
No, but you can abuse shaders to do it, if you are really desperate for more speed ;-) This is not advisable until the method of using GPU for ordinary math calculation becomes a bit more standardized, though. Right now you have to write one set of code for Nvidia and another for ATI cards. However, if you can do several operations in parallell, you can optimize a great deal by using SSE(2) instructions. Although I think the biggest savings come from just selecting a good algorithm in the first place :-) - Per _______________________________________________ Warzone-dev mailing list [email protected] https://mail.gna.org/listinfo/warzone-dev
