Property Value

These flags can be used to control shadow map caching. IsCascadeLocked[i] determines if the ShadowMapRenderer updates the cascade with index i or if it reuses the cached shadow map. Per default, all flags are and the shadow maps of all cascades are updated every frame. If the flag of a cascade is set to , the shadow map of the cascade is not rendered; the result of the last frame is used instead. The application can use this flags to determine when cascades need to be updated. (Note: If a flag is changed, it keeps this value until it is changed again. The flags are not automatically reset.)

Example usages for shadow map caching:

• Update distant cascades less often.
• Do not update a cascade if it does not contain any dynamic objects and if the camera has not move.
• Distribute cascade updates over several frames. For example: Update cascade 0 and 1 every frame. Update cascade 2 in every odd numbered frame. Update cascade 3 in every even numbered frame.
