SoGLBufferObjectIsValid Method |
Query if the buffer is valid in the current context.
Namespace: OIV.Inventor.Devices
Notes:
It is not necessary to bind an OpenGL context to call this method.
The buffer object will be invalid until memory is allocated, either explicitly (see OIV.Inventor.Devices.SoGLBufferObject.SetSize(System.UInt64)) or implicitly (e.g. mapping from another buffer).
The buffer object will be invalid after calling OIV.Inventor.Devices.SoGLBufferObject.ClearInstance().
