The screenshot looks like it was built with settings.render=0, or equivalently, on a system without the vulkan libraries installed. Check ./asy --version and the output of ./configure. You can also try it on the headless ualberta server: https://asymptote.ualberta.ca/

I should also mention that Asymptote uses GLFW now, not freeglut. If you get an error message about freeglut, you definitely need to upgrade to Asymptote 3.12.

-iconify is now obsolete; it is still accepted but has no effect on any platform. I haven't heard of any timeout issues on the ualberta server. I think we put in a timeout of 1 minute but we can increase that if anyone finds that this is not enough. Do you mean the command-line Interface or the web interface?

Hi Sean, Have you tried the -offscreen flag in Asymptote version 3.12 (with the vulkan libraries installed)? It should provide exactly the functionality that you want. Regards, -- John

Asymptote: 3.12 Released

A Vulkan renderer was implemented, with a dynamically loaded OpenGL fallback. SRGB color space rendering is supported via settings.srgb. HiDPI displays are handled for both renderers via settings.devicepixelratio. A -vsync option was added. The fitscreen modes were fixed. PBR material lookup was moved from the fragment shader to the vertex shader, eliminating per-fragment SSBO reads and branching. Emissive PBR lighting now supports nolight. The V3D serialization reads version 1-2 and writes 2, which...
