Description
glBindBuffer binds a buffer object to the specified buffer binding point. Calling glBindBuffer with target set to one of the accepted symbolic constants and buffer set to the name of a buffer object binds that buffer object name to the target. If no buffer object with name buffer exists, one is created with that name. When a buffer object is bound to a target, the previous binding for that target is automatically broken.
Buffer object names are unsigned integers. The value zero is reserved, but there is no default buffer object for each buffer object target. Instead, buffer set to zero effectively unbinds any buffer object previously bound, and restores client memory usage for that buffer object target (if supported for that target). Buffer object names and the corresponding buffer object contents are local to the shared object space of the current GL rendering context; two rendering contexts share buffer object names only if they explicitly enable sharing between contexts through the appropriate GL windows interfaces functions.
