Co-ordinates...

Recommended Posts

Hello friends, 1) I am currently rotating a cube and translating it by a random no. After a certain period i want the current Co-ordinates of the vertices of d cube in terms of world view... I searched in this forum but couldnot get how to perform it.. if u can pls give step by step method it would be great help to me. 2) After random rotations, Can the angles made by local axis with the world view axis be found? Thanks.

Well, vertices you pass through glVertex3* are defined in an object space. In order to get vertices coordinates in a world space, you have to multiply each vertex by a modelview matrix. And you have to do it manually. Modelview matrix can be obtained from OGL by getFloatfv(...).

Yes. As far as I know, try searching for Euler angles.

Cheers!
