•This how the gluLookAt parameters
are used to generate the eye
coordinate system parameters:
• VRP
= eye
• VPN =
(lookat - eye) / || (lookat - eye)
||2
• VUP =
VPN ´ (up ´
VPN)
•The eye coordinate
system parameters are then used
in translation T(VRP) and rotation R(XYZ ®VRC)
to get the view-orientation matrix
