Onloaded Shadows - Retired

Onloaded Shadows

Intel Corporation


This sample has been retired as it either was developed for earlier generation hardware or the sample has been superseded by a newer sample with an advanced algorithm. The sample is still available for download if desired.

Features / Description

Onloaded Shadows is a technique by which shadow maps can be calculated asynchronously on the CPU. By using cascades, the shadow map for objects near the camera are calculated every frame on the GPU, but the shadow maps for objects in the second cascade and beyond are calculated less often on the CPU. This allows for better work balancing across the CPU and GPU.
