/*
This example implements projective cascaded shadow mapping. This technique splits up the camera frustum into
2020-01-12 12:54:41 +01:00
multiple frustums with each getting its own full-res shadow map, implemented as a layered depth-only image.
2017-12-23 13:32:09 +01:00
The shader then selects the proper shadow map layer depending on what split of the frustum the depth value
to compare fits into.
This results in a better shadow map resolution distribution that can be tweaked even further by increasing
the number of frustum splits.
A further optimization could be done using a geometry shader to do a single-pass render for the depth map
cascades instead of multiple passes (geometry shaders are not supported on all target devices).
