Property Documentation

float FovX [get, set]

Field of view along X axis.

If you set the field of view with this property, X becomes the main fov direction for this Frustum, and FovY value's correctness will depend on Aspect's value.

float FovY [get, set]

Field of view along Y axis.

If you set the field of view with this property, Y becomes the main fov direction for this Frustum, and FovX value's correctness will depend on Aspect's value.
