V5SR10 Graphics Issue

Updated Rhino V5 to SR10 and graphics problems happen with VSR Real Time Render Display. I also run RhinoGold and the problem doesn’t exist with the display of the same scene. I am posting images of the identical scene as displayed from within RhinoGold and within Rhino V5SR10.

This is a graphics problem within Rhino, not a graphics card problem.

Update…

With the update to SR10, there is a glitch within OPENGL settings…I solved my problem by turning off “use accelerated hardware modes” and exiting rhino. Restarting Rhino and re enabling “use accelerated hardware modes” brought back the correct display in my viewport.

@jeff, can you please see if you can make sense of this behavior?

I’m not sure what took place or why restarting Rhino did anything. I’m also not exactly sure what VSR does or “assumes” about Rhino’s OpenGL context. I do know that VSR uses a Stencil Buffer, however there is no guarantee that the context Rhino uses contains a stencil buffer. Rhino tries to obtain a context that supports all of the buffers, but that doesn’t mean it actually gets one, so it starts back peddling until it does…and losing the stencil buffer is one of the first things it does.

It’s possible that for some reason the current session of Rhino couldn’t get a context that VSR could use, and closing down Rhino and restarting it and then re-initializing the OpenGL subsystem somehow got things working again…but I have no idea why that would be, nor do I know why SR10 would be any different than previous versions.

I’m not convinced the problem fixed itself either, so BrianJL I would expect things to go bad on you again, so if they do, there are some hidden commands we can try that will dump specific diagnostic information…and I’d like to dump them when the problem is occurring, and then dump them again when the problem is fixed (assuming you can fix it again doing the same steps).

Feel free to email me directly if/when you experience this problem again.

Thanks,
