Has anyone tried creating a New Volume with the Medical Example scene?


I am working with the Medical Example scene in HoloToolkit-Examples. The scene works fine. Now I am trying to create a New Volume. I am using the BrainSlices directory and image files for testing and left the values exactly the same.

However, when running Create->Volume Information, it reports the following error:

IndexOutOfRangeException: Array index is out of range.
HoloToolkit.Unity.VolumeBuffer`1[UnityEngine.Color32].SetVoxel (Int3 pos, Color32 val) (at Assets/HoloToolkit-Examples/Medical/Scripts/VolumeBuffer.cs:54)

  • any update tried as above an received same error

  • I actually came across the same issue a year after you. Have you solved the problem? I got the same error message and am not able to create a new volume. Even when I'm using the same images as the sample, it always says "Array index is out of range". Or does anyone know how this issue can be solved?
