|
||
|
|
* PerspectiveLens, it doesn't respect field-of-view or focal length
|
||
|
|
* parameters, and adjusting these will have no effect. Instead, its field of
|
||
|
|
* view is controlled by adjusting the film_size; the orthographic lens
|
||
|
|
* represents a planar projection onto its imaginary film of the specified
|
||

|
* size, hanging in space.
