[Solved]Applying SoReorganizeAction on a scenegraph

Hi! Based on https://grey.colorado.edu/coin3d/classSoReorganizeAction.html I would like to simplify a scenegraph to get a VBO-friendly one. I tried: from pivy.coin import SoSeparator from pivy.coin import SoReorganizeAction rootScene = SoSeparator() rootScene.ref() sg = FreeCADGui.ActiveDocument.Act...

PS: The behaviour described at the beginning should be reported as bug?
Yes, but this can be a bug in the GPU driver too. You should try to reproduce this on a different PC (different GPU).
But, since VBO is the more modern (and faster) than default path, I think you shouldn't worry about it.

Re: OpenXR/OpenVR (virtual reality support)

Thanks! There is one thing, that worries me - SoSceneManager::render is pretty slow with huge models. In the worst scenario I got ~13 fps and ~30% GPU utilisation. Using SoRenderManager (since event handling is not very important for VR) instead does not change much. Low fps and big latency (especia...

Re: OpenXR/OpenVR (virtual reality support)

Is it possible to run my Rift S on CATIA with this? Rift S: Yes. Catia: No, at least not with this script. ---- I have some issues to be ironed out, there is probably an error in cameras configuration (objects are too big, moving too fast). Update: this needs more testing, added a simple test file ...

Re: OpenXR/OpenVR (virtual reality support)

Lets put this on Github or Gitlab, so people can pull and test quickly and contribute code more easily. Done. I updated the original post. At this moment mostly(at least I hope so...) correct rendering with rotation and position tracking is possible. I found the culprit of rendering the same image ...

OpenXR/OpenVR (virtual reality support)

This thread continues discussion from a thread about Oculus Rift. I would like discuss here about wider VR hardware support. A few weeks ago an open VR/AR standard has been was presented: OpenXR. Waiting for OpenXR hardware adoption (manufacturers like Oculus or Valve announced future support) I've ...

Re: FreeCAD-VR: Oculus Rift

I started some tinkering with OpenVR (since OpenXR does not support my hardware yet). My initial idea was using SoOffscreenRenderer to render textures just like jriegiel did. But it seems that this method does not work anymore(?). Even as simple example as this crashes for me with X Error of failed ...
