i am writing inventory in opengl and rest of my game in directx. i need to ask how i transfer the perspecsitve matrix from opengl over to directx so that i can interact the two. when i have inventory in opengl it rotates funny and i think cause is directx. if i can just transfer perspective matrix from opengl to directx i think i will hav ethe porblem licked. can anyone give me some hints on it is this game companies do this?
