Grasshopper default display glitch

Interesting @andheum

Is there a Quadro K2100M in the Seattle office that could be used for testing? @BrianJ

How about you @jeff?

@andheum Could you try getting latest drivers for your video card? That would help eliminate one possible issue.

Thanks David - I’ve updated my drivers so now:

NVIDIA Corporation
Quadro K2100M/PCIe/SSE2
OpenGL version: 4.5.0 NVIDIA 376.33
Render version: 4.5
Shading Language: 4.50 NVIDIA
Driver Date: 12-11-2016
Driver Version: 21.21.13.7633

Maximum Texture size: 16384 x 16384
Z-Buffer depth: 24bits
Maximum Viewport size: 16384 x 16384
Total Video Memory: 2 GB

However even prior to updating, I restarted Rhino and it behaved as expected. Tried reproducing the same steps - in the Rhino display environment and in GH - and nothing, everything looked normal. Will let you know if I can reproduce consistently. The things I was mucking about with in Rhino when it occurred were the rendered viewport, skylight, ground plane, shadows, etc… if that gives any clues. Will keep an eye on this and keep you appraised.

Okay, thanks. Keep us up to date!

also re: the slowness zooming in the rendered viewport, it seems to only occur when the skylight is on and only when using the mouse wheel - other modes of zooming and rotating are smooth. Gif below makes the “smooth” look choppier than it is, but you get the idea - first is mouse wheel scroll, then ctrl-right click drag:

Yep, I am aware of this and it’s on my list of things to look at.

I don’t have any Quadro cards here but it sounds like the driver update helped.

I believe this is a laptop card, so reproducing it on a desktop equivalent is most likely not going to happen. I can look for the K2100 I have (but I think I sent it to Scott or someone in Seattle). Why do we think it’s related to the card?

No need to take a look. A driver updated fixed the issue.

Hi @DavidEranen - unfortunately I am seeing this glitch re-emerge even after updating my graphics card. Here are my current stats:

NVIDIA Corporation
Quadro K2100M/PCIe/SSE2
OpenGL version: 4.5.0 NVIDIA 376.33
Render version: 4.5
Shading Language: 4.50 NVIDIA
Driver Date: 12-11-2016
Driver Version: 21.21.13.7633

Maximum Texture size: 16384 x 16384
Z-Buffer depth: 24bits
Maximum Viewport size: 16384 x 16384
Total Video Memory: 2 GB

I’m using this build:

Work In Progress
(6.0.17003.8321, 01/03/2017)

What’s strange is it was working fine for a while - it wasn’t happening at the beginning of my Rhino session but now it’s started again. I was playing around with different display modes (like Arctic) and doing some hi-res screen captures with ViewCaptureToFile. Let me know if there’s anything I can do to test to help get to the bottom of the issue.

It’s also happening on my other machine, which has a totally different card. So not sure that’s the issue…

NVIDIA Corporation
GeForce GT 650M/PCIe/SSE2
OpenGL version: 4.2.0
Render version: 4.2
Shading Language: 4.20 NVIDIA via Cg compiler
Driver Date: 8-30-2012
Driver Version: 9.18.13.623

Maximum Texture size: 16384 x 16384
Z-Buffer depth: 24bits
Maximum Viewport size: 16384 x 16384
Total Video Memory: 1 GB

Only transparent material display from grasshopper seems to be affected. Using custom preview w/ an opaque material registers no artifacts.

andheum,

We’re currently working on fixing an issue similar to this. Thanks for reporting!

RH-36343 is fixed in the latest WIP

This problem is back in the latest Beta, though it seemed to have gone away for a while.

Thanks, I’ve reopened the issue.

incidentally, that’s a 3d model of the tattoo I just got. Drew the mockup with procedural stippling in grasshopper :smile:

First Rhino/GH-designed tattoo?

Did you apply the tattoo with a robot controlled by Grasshopper? :stuck_out_tongue_winking_eye:

Does this only happen with Grasshopper geometry or does it happen with old fashioned Rhino geometry too?

only grasshopper geometry.

Can you share your model with me? @DavidRutten and I both can’t repeat the bug with our attempts, and no I’m not asking just so I can get a matching tattoo :slight_smile:
