Static Shadow Volume Setup
|
|
|
|
A static shadow is cast from a static model touching a static light.
|
|
A static shadow volume extends to infinity which allows the end caps to be omitted
|
|
when the view is outside and far enough away from the shadow volume.
|
|
|
|
A static shadow volume is created at map load time and this job determines whether or
|
|
not the end caps need to be rendered, whether or not the shadow volume needs to be
|
|
rendered with Z-Fail, and optionally calculates the shadow volume depth bounds.
