Hi, I have a few questions about Virtual Reality Implementation on Slicer I have a volume rendering that will not appear on Virtual Reality even though it appears on my 3D views. Why is this so and how do I fix it? Ex: Perspective from Slicer Desktop: [image] Perspective from Slicer Virtual Rea…

[image] triple_axel: I have also downloaded the latest nightly version of Slicer 4.11.0 and still do not see the volume rendering In your scene, Volume Rendering is hidden in the virtual reality view. You can enable it in Volume rendering module / Inputs section / View: [image] [image] t…

I had issues like this in past versions (4.9) when the display node of the volume rendering did not have the VR view included (VR view node ID was not in ViewNodeIDs). Try to create the scene from scratch in 4.10.1. We want this a lot too. The main task that needs to be done first is to allow u…

Thanks for the prompt reply. 2) I will continue to follow the development of the VR segmentation tool. Sounds very cool and would be very helpful! In regards to 1) and 3), I am currently working on slicer 4.10.1 but I still do not see any virtual reality view of the controller models (after checki…

Make sure you updated to the latest version of SlicerVirtualReality extension (you can check for updates and then install updates in the extension manager). [image] triple_axel: I still do not see any virtual reality view of the controller models Controller display works fine for me for Wind…

I have attached an example scene in gdocs: https://drive.google.com/file/d/16FwaOCQseLVeWhtq9ytA9ofcI-g331ej/view?usp=sharing How do I enable the controller transforms? They are visible on slicer as seen below: [image] , however turning on and off the view does nothing. If I apply the controller…

Thank you so much for all the help! The reason I’m using Oculus is because I’m borrowing it temporarily from someone else to explore the virtual reality feature on slicer.

Hi, sorry I had another question about the views. Is there a way through Python to automatically set views to include the “virtual reality view”? I’ve attempted to do it with getting the volume rendering node: volumeRendering = slicer.mrmlScene.GetNodesByName(‘GPURayCastVolumeRendering’).GetItemAsO…

[image] triple_axel: and setting the view of the volume rendering node like so: volumeRendering.SetViewNodeIDs(vrViewNodeID) This should not work, and you probably got an error as well. Instead, call AddViewNodeID

Thanks for the help, Just wanted to write an update for this that I wrote a small work around for the “eraser effect” in Virtual Reality (in the meantime before you integrate the Qt GUIs in VR). Through this code, a sphere segmentation is created in VR that gets transformed to the right hand cont…

The problem should go away if the segmentation is updated more quickly. For example, you can disable smoothing (checkbox in “Show 3D” button’s drop-down menu) to make 3D view updates magnitudes faster.

We are looking to be able to control the ROI in VR with controllers. Has anyone been able to figure out visualizing and controlling the ROI in VR space?
