Model Comparison

I have a couple of questions.

1. Why does the ModelViewer example app use ModelVisual3D instead of HelixVisual3D?

2. I would like to load up 2 models into a HelixViewport3D, and use a slider to change opacity between the 2, for comparison purposes.  I would have to use a switch to manipulate 1 model at a time.  Any thoughts as to the best way to accomplish this?

Thanks,

Paul

1. Use ModelVisual3D to show models loaded from the supported file formats, use HelixVisual3D to show 3D helix models.

2. I suggest you use DiffuseMaterials on your models, and bind the opacity property of the brushes
