Chapter 9: Viewing the Scene
Figure 9-5 Horizontal and Vertical Fields of View Offsets
The offset angles are measured starting at the -z axis, following the right-hand rule. For
example, the horizontal FOV offset angle shown in Figure 9-5 is positive.
To specify the offsets, use one or both of the following csPerspCamera methods:
void setHorizFOVOff(csFloat horizFOV);
void setVertFOVOff(rfcsFloat vertFOV);
There is a corresponding get...() field for each set...() field.
