virtual void makVrv::DtGlTextureResidencyManager::makeResidentIfNecessary ( void *  gContext, GLuint  textureID  )

virtual

Check if a texture is resident in a given context. If not, make it resident.

virtual bool makVrv::DtGlTextureResidencyManager::makeNonResidentIfNecessary ( void *  gContext, GLuint  textureID, bool  canDelete  )

virtual

Make a texture non-resident in GPU memory If canDelete=true, the function will try to delete the texture and return true if it succeeded in deleting the texture.

virtual GLuint64 makVrv::DtGlTextureResidencyManager::gpuTextureAddress ( GLuint  textureID ) const

virtual

Get the Gpu address of a texture.

virtual bool makVrv::DtGlTextureResidencyManager::isTexture ( GLuint  textureID ) const

virtual

check if the texture is in fact an OpenGL texture

virtual DtGlTextureResidentMemoryTracker* makVrv::DtGlTextureResidencyManager::tracker ( ) const

virtual

get a tracker since residency is per gc, there's a tracker per gc just get the first tracker in our map

virtual DtGlTextureResidentMemoryTracker* makVrv::DtGlTextureResidencyManager::getOrCreateTracker ( void *  graphicsContext )

protectedvirtual

get or create the tracker.
