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...

For now, just a primitive list of spheres.

This should be an optimized data structure for speed.

DtPagedNodeStatusMap DtBoundingVolumeTerrainSourceTracker::myPagedInAreas

protected

List of paged in volumes. Used for tracking usage for paging out.

bool DtBoundingVolumeTerrainSourceTracker::myInvalidFlag

DtSpatialNodeBoundingInfoContainer* DtBoundingVolumeTerrainSourceTracker::myPagedOutSpatialNodeContainer

protected

Spatial subdivision for finding relevant bounding nodes.

The subdivision is projected into topo from the origin of the terrain. Dimensions are specified in terrainOptions.mtl as "spatial-subdivision-dimensions".
