Detailed Description

Interface for OpenGl resource with following meaning:

Constructor & Destructor Documentation

OpenGl_Resource::OpenGl_Resource ( )

Empty constructor.

virtual OpenGl_Resource::~OpenGl_Resource ( )
virtual

Destructor. Inheritors should call Clean (NULL) within it.

Member Function Documentation

virtual void OpenGl_Resource::Release ( OpenGl_Context theGlCtx)
pure virtual

Release GPU resources. Notice that implementation should be SAFE for several consecutive calls (thus should invalidate internal structures / ids to avoid multiple-free errors).

Parameters
theGlCtx- bound GL context, shouldn't be NULL.

Implemented in OpenGl_Texture, OpenGl_ShaderProgram, OpenGl_VertexBuffer, OpenGl_Font, OpenGl_ShaderObject, OpenGl_TextureBufferArb, OpenGl_CappingPlaneResource, OpenGl_VertexBufferCompat, OpenGl_FrameBuffer, OpenGl_Sampler, OpenGl_LineAttributes, and OpenGl_PointSprite.
