I was trying to get at the MESA driver from VTK but realized that will not work as VTK is not getting a context it likes. glxinfo may report the driver that mesa is using. A driver that should work is llvmpipe but often Mesa is built with other drivers that try to use the underlying hardware and sometimes those do not work for some reason.

MacPorts provides mesa 17.1.6, which supports OpenGL 4.5. vtk requires OpenGL 3.2 or later, so all should be ok. However, vtk says it can't find a recent enough version of OpenGL, and indeed glxinfo says "OpenGL version string: 2.1 ATI-1.68.20". Is it possible to use OpenGL 3.2 on macOS? If it is possible, can someone tell me how to change the vtk code so that it works? I know roughly where vtk initializes OpenGL, but I don't really understand what it's doing.<br> <br> I *can* get vtk to work if I compile it for quartz and not X11, using Apple's OpenGL libraries instead of mesa, but for numerous reasons it would be very convenient if I can get it to work on X11.<br> <br> I've asked on the vtk and MacPorts lists, but nobody seems to know the answer. Someone suggested I try here.<br> <br> Many thanks,<br> Steve<br> <br> _______________________________________________<br> mesa-users mailing list<br> <a href="mailto:mesa-users@lists.freedesktop.org" target="_blank">mesa-users@lists.freedesktop.org</a><br> <a href="https://na01.safelinks.protection.outlook.com/?url=https%3A%2F%2Flists.freedesktop.org%2Fmailman%2Flistinfo%2Fmesa-users&data=02%7C01%7Cstephen.langer%40nist.gov%7C3d306ba4527043af569c08d61396a277%7C2ab5d82fd8fa4797a93e054655c61dec%7C1%7C0%7C636717935028000746&sdata=VGTF557RLr92odYV3W2Z4MTEOWRZ8IZ82ZK545A9BQ0%3D&reserved=0" target="_blank">https://lists.freedesktop.org/mailman/listinfo/mesa-users</a><o:p></o:p></p> </blockquote> </div> <p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto;margin-left:1.0in"> <br> <br clear="all"> <br> -- <o:p></o:p></p> <div> <div> <div> <div> <div> <p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto;margin-left:1.0in"> Ken Martin PhD <o:p></o:p></p> <div> <p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto;margin-left:1.0in"> Distinguished Engineer<br> <span style="font-size:9.5pt">Kitware Inc.</span><o:p></o:p></p> </div> <div> <p class="MsoNormal" style="mso-margin-top-alt:auto;margin-bottom:12.0pt;margin-left:1.0in"> <a href="https://na01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fmaps.google.com%2F%3Fq%3D101%2BEast%2BWeaver%2BStreet%2B%250D%250ACarrboro%2C%2BNorth%2BCarolina%2B%250D%250A27510%2BUSA%26entry%3Dgmail%26source%3Dg&data=02%7C01%7Cstephen.langer%40nist.gov%7C3d306ba4527043af569c08d61396a277%7C2ab5d82fd8fa4797a93e054655c61dec%7C1%7C0%7C636717935028000746&sdata=rXa4S4aof8xCSKwv1ORmqROT47iMAPrv14NhXo6uQws%3D&reserved=0" target="_blank">101 East Weaver Street</a><br> Carrboro, North Carolina<br> 27510 USA<o:p></o:p></p> <div> <p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto;margin-left:1.0in"> <span style="font-size:10.0pt;font-family:"Tahoma",sans-serif">This communication, including all attachments, contains confidential and legally privileged information, and it is intended only for the use of the addressee.
