Hi Tom, So I can take into consideration that all the OpenGL things doesn't work on chimeraX?

Unfortunately the modern OpenGL graphics standard (core profile) used by ChimeraX only supports linewidth 1 while older OpenGL standard (legacy profile) supports linewidths > 1 (usually up to 10 pixels). It is quite complex to support linewidths > 1 in modern OpenGL — it requires drawing triangles instead of lines and special GPU shader code. In the future we are may switch ChimeraX graphics from OpenGL to Vulkan which is the next generation of OpenGL and Vulkan allows linewidth > 1. I will remove the lineWidth option from the volume command for now. Tom

Hi Yehuda, I don’t think you are doing anything wrong; in ChimeraX, the lineThickness option doesn’t work for me either, although it works fine in Chimera on the same computer — we will look into it.

P.S. there is a chimerax-users@cgl.ucsf.edu mailing list too <http://rbvi.ucsf.edu/chimerax/docs/contact.html>

Hi all, I wanted to use chimeraX to use some commands on mesh display. Some works like meshLightning but others like lineThickness doesn't I use volume #1 lineThickness 10 (or any other integer) but nothing seems to change. What am I doing wrong? Yehuda Halfon
