makVrv::DtIndirectGlTextureObject Class Reference

Encapsulate an OpenGL texture object that is created/used in indirect rendering.

The life time of these is managed by DtIndirectGlTextureObjectManager/

See DtIndirectGlTextureObjectManager for detailed documentation of this c;lass

virtual bool makVrv::DtIndirectGlTextureObject::isResident ( const void *  glContext ) const

virtual

Whether resident in this context. This function does not need a valid gl context while calling. Just the gc pointer corresponding to the passed in gl context.

virtual void makVrv::DtIndirectGlTextureObject::makeResident ( )

virtual

This function needs a valid gl context during the call.

virtual void makVrv::DtIndirectGlTextureObject::makeNonResident ( )

virtual

This function needs a valid gl context during the call.

virtual int makVrv::DtIndirectGlTextureObject::numOfContextsResidentIn ( void  ) const

virtual

how many contexts is this resident in? This function does not need a valid gl context while calling.

virtual uint64_t makVrv::DtIndirectGlTextureObject::textureAddress ( void  ) const

virtual

This does not change for the lifetime of the DtIndirectGlTextureObject (gl texture object) This address is made resident/non-resident externally in the DtIndirectTextureResidencyManager and the first time the DtIndirectGlTexture is created in DtIndirectGlTextureObjectManager.

virtual void makVrv::DtIndirectGlTextureObject::addGpuCullingUser ( const DtGpuCulling *  culling )

virtual

Currently, DtIndirectGeometry(and in reality DtGpuCulling inside of it) are the only 'users' of bindless textures. Note: In reality however we are using bindless textures in a roundabout fashion, elsewhere. See for example: https://jira.mak.com/browse/VRV-4316 So, this comment needs to be updated and the function extended/abstracted/refined when we do that properly.

virtual void makVrv::DtIndirectGlTextureObject::removeGpuCullingUser ( const DtGpuCulling *  culling )

virtual

virtual unsigned int makVrv::DtIndirectGlTextureObject::textureId ( void  ) const

virtual

the actual gl texture object id

virtual int makVrv::DtIndirectGlTextureObject::incrementNumUsers ( )

virtual

ref counting tracking for when DtIndirectGlTextureObject is used directly

virtual int makVrv::DtIndirectGlTextureObject::decrementNumUsers ( )

virtual

ref counting tracking for when DtIndirectGlTextureObject is used directly
