<br>
How can I compute the view matrix and the projection matrix from a set of lookat parameters (eye, center, and up)?<br>
<br>
I'm asking because I need to compute the MVPW for a given lookat before the camera is actually at that lookat.<br>
<br>
I'm totally stumped and any help would be greatly appreciated!<br>
<br>
Thank you!<br>
<br>
Cheers,<br>
