Screen resolution culling is disabled.

Screen resolution culling is enabled.

Only tiles for which the projection of a voxel is greater than or equal to 1 pixel on screen will be loaded. This avoids unnecessary loading of high resolution data for large volumes. However if you "zoom out" from a volume, it does not force lower resolution tiles to be used (high resolution tiles already in memory will still be used). If necessary use the OIV.LDM.Nodes.SoLDMResourceParameters.fixedResolution field to force use of lower resolution tiles.

Screen resolution culling will be enabled or not according to the flag returned by OIV.LDM.SoLDMGlobalResourceParameters.GetScreenResolutionCulling()
