the first one : i’m drawing trees using gluCyclinder. i can’t draw them directly at x/y/z so i use gltranslate/glrotate.
do these matrix-operations slow down my engine if i use them in display lists ?
the second one : do display lists save glactivetexture-commands ?
#1. They will take some time to execute, but not more than if called outside the display list.
#2. Yes.
i hope they are faster inside display lists, because if called outside, the result-matrix has to be calculated, but inside a list, the new one can be stored in memory…
i could solve this problem by drawing my own cylinder…anyone got a function for this ?
