Detailed Description

DtOsgLightPointManager registers LightPoint nodes so their TBO can be created and updated in a single place.

Main access point for adding light points to the new system. It registers the light points which (if enabled) replaces the

See Also: osgSim::LightPointNodes with; DtLightPointNodes or just passes a pointer for the; DtOsgLightPointManager to the; DtLightPointNode in the case of CDB light points. It also converts; osgSim::LightPoint objects to a light point type and manages the loading of the light point table which has the default light point types in it. Creates the; DtLightPointDrawable object that draws all the light points. Handles the creation and updating of the SSBO(Shader Storage Buffer Object) which is how the light type, light node, and light group data is passed down to the GPU. Sets up the shaders which are added as Virtual Program functions to the; DtLightPointDrawable. Sets up the imGui debug gui which can turn on debug labels and adjust the intensity of the light point groups.
