Volume Rendering in X3D

So recently I started working with X3D and have been trying to experiment around with Volume Rendering but I can't seem to get anything working. I have an X3D file with the following code in it:

<?xml version="1.0" encoding="UTF-8"?> 
<!DOCTYPE X3D PUBLIC "ISO//Web3D//DTD X3D 3.3//EN" "http://www.web3d.org/specifications/x3d-3.3.dtd">
<X3D profile='Interchange' version='3.3'  xmlns:xsd='http://www.w3.org/2001/XMLSchema-instance' xsd:noNamespaceSchemaLocation =' http://www.web3d.org/specifications/x3d-3.3.xsd '>
<head>
<component level='1' name='VolumeRendering'/> 
</head> 
<Scene>
<Group>
<Viewpoint DEF='VP' description='Basic Brain' orientation='-0.0212122 0.99986 0.012461 3.23009' position='-0.00920216 0.012033 -0.184913'/> 
<Background DEF='BG' skyColor='1 1 1'/> 
<Transform scale='0.117188 0.117188 0.117188'>
<VolumeData dimensions='1.28 1.28 1.0' containerField='children'>
<ImageTexture3D containerField='voxels' 
  url=' "datasets/nrrd/supine.nrrd"'>
 </ImageTexture3D>
</VolumeData>
</Transform>
</Group>
</Scene>
</X3D>

I grabbed this example from the following link and trimmed some of the fat in the head tag. Also, the image that they reference doesn't seem to be on the server so I'm using a different image than the one they use.

Now for some reason when I open the X3D file and try to view the scene the only thing that seems to render is the background. When I pull it up in BS Content Studio, it gives me an error declaring "Unknown node class 'VolumeData'". As for the X3D player I'm using, I use BS Content Player. Any help would be greatly appreciated because I'm at a bit of a loss right now and haven't received a word back from the BS Content Player support team.

Oh also, I have a folder on my desktop to mirror the url call of datasets/nrrd/supine.nrrd so I don't think that's the issue.

Solution

  • BS Content Player does not support the node VolumeData. But you can try to use instant player from instant reality: http://instantreality.org/downloads.
