Hi,
I have been trying to set my viewport to the shaded view - however it doest work - but all of the others.
Is it possible that my Computer does not fullfill the system/hardware requirements for this view to work?
Hi Wim,
I just read that : Rhino 6 will use OpenGL 3.3 (if available), and fallback to older specifications when required. (https://wiki.mcneel.com/rhino/rhino5videocards)
So is there maybe another problem?
Hi @melanie.paetsch
That’s an 11 years old graphics card - I think it might be time for an upgrade I know it sucks, but V6 requires a lot more oomph from the graphics card than V5 did.
That page was was primarily for Rhino 5 and was last updated in 2017 - before Rhino 6 was released - so I would read Rhino 6 will… as a declaration of then future intent rather than an imperative. But the requirement was subsequently overtaken by advances in the OpenGL spec.
I guess McNeel need to clean the misleading page up, but Wim supplied a link to the current Rhino 6 requirement.
Rhino 6 will use OpenGL 3.3 (if available), and fallback to older specifications when required.
Thanks for pointing that out. I’m not convinced that this statement is correct - I’ll run it by the developers.
At any rate, even if that statement is correct, it doesn’t say that the fallback to older specifications will actually make things work as they are intended to work.
Hi again,
I got more information from the developer. Rhino 6 will run at the OpenGL level that the GPU reports to be supporting. Your card claims to support 3.3 and Rhino 6 will use that to draw the viewports - but this is clearly not working on your machine.
One thing that you could try first is using a test command - TestGlLevelCap and set this to 21 (for OpenGL level 2.1). You will have to exit and then restart Rhino 6 after having used this command.
Note that this command was added to Service Release 15, which is now available as a SR Candidate - you will have to change the Update frequency in Rhino Options > Updates and Statistics to automatically download a SR 15 version.
The command forces Rhino to use a specific level of OpenGL and thus override what the GPU claims to be supporting. We have a set of drawing routines that use what was available for OpenGL 2.1 and hopefully this will make display modes work for you - no guarantees though…
HTH,
wim
I tried your sugested command with 21 - all the viewports went black. Setting it to 33 made it normal again but still no shaded view Is there anything else I could try?
Thank you!
Hi - a quick question. If I understood that correctly, you originally wrote that all other display modes work. Is that right, does e.g. Rendered and Raytraced work fine?
Yes that is correct! Only the shaded view is the same as wireframe and doesnt show the surfaces as supposed…For example instead of a sphere, I see three rings.
