makVrv::DtGlTextureMemoryTracker Class Reference

class to track memory for textures: -Call textureSizeChanged when the texture size changes, with the gl texture id as parameter

-Call textureDeleted when the texture is being deleted, with the gl texture id as parameter

There is no call for when texture is created, because its just a name creation call textureSizeChanged works instead (after the texture object is completed), because if there's no internal entry , one is made.

The trackedProperties() gives the cumulative usage/size of the tracked textures

get the tracked textures

static void makVrv::DtGlTextureMemoryTracker::addTextureOfInterest ( const std::string &  name )

static

call if you want to give a texture to track (file name, without path) This will track the texture through the life time of the app (create/handle residency/destruction)
