Raycast sounds more straight forward....array of vec3...I'll better start study some stuff :-D Do you think that the "4 vectors at 90°" is a good solution or something else could do the trick? anyway thanks :) 2013/9/3 Guillaume Laforge <guillaume.laforge...@gmail.com> > Or better, an array of vec3. > On Sep 2, 2013 9:49 PM, "Alan Fregtman" <alan.fregt...@gmail.com> wrote: > >> *>> First of all, it is possible to "fire" 4 vectors in 4 different ( >> consistent ) directions?
