<p>We've been implementing OpenGL plotting in Octave, and this stuff is great. I'll be reading more of this later in order to have a deeper understanding of how to do this.</p>
<p>I have a question. Do you know if there's any hope of getting offscreen plotting in OpenGL without an X server? It would be tremendously useful.</p>
<p>Thanks,

<p>I forwarded your comment to the tutorial author <img src="https://blog.beuc.net/smileys/smile.png" alt=":)" /></p>
<p>I don't know if it's possible to use OpenGL without an X server. Since OpenGL is called through X server extensions (GLX), that sounds unlikely, but perhaps there's a way to call the kernel's DRM system directly.</p>
<p>An alternative might be to implement the plotter in OpenCL.</p>
