Wiimote Desktop VR/Head Tracking / Re: Desktop VR openGL perspective projection issues
« on: February 20, 2008, 02:43:12 AM »
Thanx for your input OasisGames, i thought nobody was going to respond...
I have some questions regarding your solution:
1.
I assume the method matrixTranslate is a custom method, is this the same as going:
glMatrixMode(GL_MODELVIEW);
glLoadIndentity();
glTranslatef(x, y, 1 - z);
2.
Is this the correct order of the steps for the renedering loop?
1 load the projection matrix (glMatrixMode)
2 perform the perspective projection (glFrustum)
3 set the modelview matrix
4 translate the matrix by the head pos (glTranslateF)
5 set the camera by calling the lookat method with the head coords as indicated in the original project (gluLookAt)
6 render all objects in the scene
Thanx again
P.S I'm busy coding a simple game with this idea where you move through a tunnel specified with a BSpline and dodge objects with you head. If i can just get the perspective working right it will look awesome! If I manage to do it I'll upload the game...

) wich accepts the same basic arguments (as dictated by parameter names anyway). However it is painfully obvious that the way these two methods work is very different, and I'm having trouble finding documentation explaining the Matrix.PerspectiveOffCenterLH method in more detail (apart from: Builds a customized, left-handed perspective projection matrix.) I did find some resourses on the OpenGL method though :
