Opengl layout position
http://www.opengl-tutorial.org/jp/beginners-tutorials/tutorial-2-the-first-triangle/ WebOpenGL internally stores a reference to the buffer per target and, based on the target, processes the buffer differently. So far we've been filling the buffer's memory by calling glBufferData, which allocates a piece of GPU memory and adds data into this memory. If we were to pass NULL as its data argument, the function would only allocate ...
