Rhino WIP for Windows is using Direct3D as the primary GPU accelerated display technology. What is Direct3D? Direct3D is Microsoft’s technology for communicating with the GPU to draw 2D and 3D scenes. It is an alternative to OpenGL. [Direct3D Support | New in Rhino WIP] Why is Rhino s…

Does the switch from OpenGL to Direct3D also unlock any other capabilities or improvements that we as users will notice? For example, more efficient clipping planes, or jogged clipping planes? Were there aspects of graphics rendering that were previously difficult or impossible but will now be feasi…

Hi Moby - [image] Moby Dk: Does the switch from OpenGL to Direct3D also unlock any other capabilities or improvements that we as users will notice? Weren’t these questions answered in the first post of this thread? [image] Steve Baer: Why is Rhino switching to Direct3D? Stability The pr…

[image] moby-dk: are these changes mainly about making your work easier going forward? I’m not sure how now having to maintain yet another (3rd) graphics engine “makes our work easier”… So no, this is not one of the reasons we’re doing this. -J

Ah, don’t get me wrong. I know this means extra work for you. By “making it easier” I meant that it will apparently be easier for you to support more machines - but that’s not important, poor choice of words on my side. I understand we can expect a performance boost, but it seems not everything has…

Amazing, works great ! Thanks for the quick fix :slight_smile: For reference, my bootcamp drivers are not the official Apple-provided ones (from 2020..), but updated AMD drivers from 2025. I don’t know if/how Rhino’s Direct3D works on 2020 drivers.

[image] moby-dk: I asked whether there are any display/rendering features that were difficult or impossible to implement with OpenGL but would become easier or possible with the move to Direct3D. There isn’t anything you can do using DirectX that you can’t do using OpenGL and vice versa…they’…

Rhion 9.0.26006.14225 in Direct3D There is a Draw Problem with DrawMeshShaded(Mesh mesh, DisplayMaterial material, int faceIndices); and e.Display.DrawMeshFalseColors(); [Video 2026 01 13 1]

Hi @taraskydon Please provide examples of what you’re doing so that we don’t have to type everything up, guessing about what’s being done and how. It’s quicker and more efficient if we can just run something and place breakpoints. It also means I’ll be able to look at things “now” (sooner than lat…

Rhion 9.0.26006.14225 Unfortunately, this compilation is very unstable and GH C# node does not work in Grasshopper. I will write a test when a stable version appears. :sweat_smile:

Thanks for letting us know. Ya, I used the 2025 drivers on my bootcamp’d iMac when fixing this…but it should all work on the 2020 drivers as well, since we only target DirectX 11.
