Hi,
I've been using Houdini for my final year project in Electronics with Music Tech. The project involves analysing shape and colour details of 3D objects, and using that info to generate sound. The sound gen takes place in Reaktor, while the 3D stuff all happens in Houdini.
I've got a site up for demoing/testing, and if you'd like to have a look at that, it would be very appreciated. There are other posts on the blog with more info about the project, although not so much about implementation… this is something I'll be happy to answer questions about :-)
The test site is:
