I am giving a workshop at the National Council on Measurement in Education in April. The workshop is focused on showing multidimensional item response theory probabilistic models and their components using Mathematica. For example, one graphic is where I have a 3D plot of a response surface and the user can move the slider bars to change the parameters of the model and see the result on the response surface. In the College of Education at Iowa we just received several zSpace computers and accompanying software. Their URL is https:\zSpace.com. I was wondering if anyone had used zSpace equipment and software with Mathematica 3D graphics.
