DtBoundingVolumeTerrainSourceTracker Class Reference

A DtBoundingVolumeTerrainSourceTracker tracks data from a paging terrain source for purposes such as determining whether the data necessary to intersect with specified geometry is available, generating commands to page in that geometry, and to determine what to page out when necessary. More...
