push/popmatrix()

Hi... I''ve got 2 questions: 1) where from does pushmatrix() know, what matrix it''s supposed to push onto the stack? the following to lines? so would this push glRotatef() and glTranslatef() onto the stack right? glpushmatrix(); glRotatef(*whatever*); //<-------\ glTranslatef(*whatever*);//<-----| glpopmatrix(); // takes of these-/ ? 2) is it able to put glRotatef() and glTranslatef() between glBegin() and glEnd() ? thx. cya, Phil

ok...

resume: i''ll make for each frame of the animation 1 displaylist.
right? this means, that i takes more RAM, but i wouldn''t have to rotate and transform and loadidentity() that much at runtime....

ok,
thx a lot for all of your help...

cya around,

Phil

All you will have to do is orient the model in your world with translate''s and rotate''s and then call the display list of the proper frame of animation. Good luck.

One thing to note, once you have built the display list, you can get rid of your vertex info (saves RAM that way).
