Hi

Use glBufferSubData to modify the data store. Mapping and unmapping should be done on the rendering thread and when the OpenGL context is current. I would rather use a timer only to know when the data needs to be refreshed but I would perform this refresh on the rendering thread when the OpenGL context is current. You could modify your code by using GLDrawable.invoke() and put your call to fillVertexBuffer into a GLRunnable.
