Transparent 3d objects

[AMyth]

I used http://decibel.ni.com/content/docs/DOC-7871 as a starting point and was trying to change parameters to be able to control transperancy from 0 all the way to 100%. However, it looks like, the 3D picture toolkit is good at handling 100% but when I specify 0% I can still see through the object. Is there a setting that I am missing?

Hi Amit,

This was reported to R&D (# 177501) for further investigation.  A possible workaround is to create a mesh instead and use that to create a box using the SetMeshParameters method in an invoke node.  Are you intending on using boxes for your final application?  Or is this just a test to see if it works?

Jared,

I am going to use VRMLs. The boxes were for a proof of concept.

Amit,

Have you tried loading a VRML and using that?  It could work for this situation using pretty much the same code as is used for the boxes.

[AMyth]

Looks like VRMLs don't support all features. Can't even change thier color.

Amit,

I'm not extremely familiar with VRML, but I thought you could specify the transparency in there.  Do you know if this is possible?  What program are you using to create these VRML objects? 

[AMyth]

We are using Solid works. VRMLs, atleast in older versions of the 3D picture toolkit were built using meshes. However, with 2009 its unclear what techniology is used. However, the standard transperency stuff doesn't work for VRMLs.

Amit,

I think I'll need to ask around and see if anyone's tried doing this before.
