Macha Posted September 15, 2011 Share Posted September 15, 2011 Is it possible to read an i3d file and get a "normal" volume from it? I know we can use it in shaders but I want to read i3d files and get a standard voxel volume from it. I thought the isosurface node could do that but while I get no errors I don't get anything at all. Quote Link to comment Share on other sites More sharing options...

Check out your density threshold and channel name in i3d (i3dinfo is a useful tool for inspection). Another option is texture3d in Volume Vop. skk.

Macha Posted September 15, 2011 Author Share Posted September 15, 2011 Ahoy Symek! I seem to do everything by the book but can't see a result. I use a rop to write a density field to i3d. Sounds feasable? Quote Link to comment Share on other sites More sharing options...
symek Posted September 15, 2011 Share Posted September 15, 2011 (edited) Ahoy Symek! I seem to do everything by the book but can't see a result. I use a rop to write a density field to i3d. Sounds feasable? Aha! Isn't it an old good busted geo2i3d Rop? (from a couple of weeks (months!)). Perhaps you're not generating i3d at all* (at least 11.1.22 it still doesn't work). Here is a solution (though I was sure it was already fixed). edit: I'm attaching test file. It does work here. * - i.e. blank volume. hth, skk. teapot.i3d.zip Edited September 15, 2011 by SYmek Quote Link to comment Share on other sites More sharing options...
Macha Posted September 16, 2011 Author Share Posted September 16, 2011 Oh man, thanks for that! A bug! I would never have worked out that one. You just made my life easier Symek. Quote Link to comment Share on other sites More sharing options...
