RemarksThe SoLDMResourceManager maintains information about the resources available on the machine and constrains the data flow to these resource limits. The major constraints are texture memory, main memory, and main memory-to-texture memory bandwidth. Each of them can entirely be specified by the application, at any time.
It queries the SoLDMTileManager for main memory constraints and also queries the SoLDMNodeFrontManager for texture memory and bandwidth constraints. The SoLDMTileVisitor queries the Resource Manager to know the tiles of which resolution that must always be kept in main memory and tiles of which resolution the application never wants to load.
