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…

[image] JimCarruthers: That this move is largely about compatibility with ARM is interesting…illustration that there have got to be more developers working on making games with Direct3D then there are even USERS of OpenGL 3D CAD. ARM is definitely one reason. The OpenGL drivers on ARM complet…

[image] JimCarruthers: Well after 45 seconds the only glaring issue is that there is no feedback when dragging around the viewport boundaries. Thanks; I’m working on a fix for this now Dragging lines are not drawn : RH-88342 When using Direct3D, the drag lines when dragging the w…

Hallelujah! OpenGL deserved its retirement years ago! Blender dropping it for Vulkan and Rhino dropping it for D3D is just great news! Can’t wait to give it a go!

[image] Graphic Glitch with Direct3D Serengeti (Rhino WIP) i just did a restore on the nvidia settings to default and it seems to have gone away and is working normal there has to be something on there causing this Check this might help

I’m running Rhino on a virtual machine (VMWare Workstation on a Linux host). Anti-aliasing now works under Direct3D, it does not using OpenGL. Have not noticed any adverse affects other than the display-modes “Artistic” and “Pen” no longer properly working using Direct3D, they seem to not delete t…

[image] JimCarruthers: Presumably all the information required is there…the driver date and (DX 11) Primary display: NVIDIA GeForce RTX 2070 (NVidia) Memory: 8GB, Driver date: 1-26-2025 (M-D-Y). DirectX(11) 11 dxdiag.exe tells me DirectX 12. What is correct? Time of this report: 7/16/2025…

[image] Charles: dxdiag.exe tells me DirectX 12. Dxdiag reports the highest version installed. My Win11 PC has the directX DLLs from 8 thru 12 but only reports 12. The version used by a program depends on which one it was compiled for.

Jeremy is correct. There are several versions of Direct3D installed with Windows and 12 is the most recent version. We are targeting Direct3D 11 in Rhino 9 because it has all of the features we currently need and there are older systems we want to support that do not support Direct3D 12 (there are s…
