Fresnel wrapper class to quickly and easily view GSD files in Notebooks

[chrisjonesBSU]

This works as is right now, but is still a WIP, and open to feedback!

This is really just a wrapper for Fresnel that is designed around loading a GSD file, and visualizing different frames. All of the fresnel objects are automatically set up, and there are setters for just about all of the parameters for these objects making it easy to change something and view it.

Looks like some lines in this method are untested.

Yeah, I need to get a test gsd that has multiple frames, and values set for snapshot.particles.image

@chrisjonesBSU We can also visualize the simulation box by adding this line:

L = pps.snapshot.configuration.box[0]
box = fresnel.geometry.Box(pps.scene, [L, L, L, 0, 0, 0], box_radius=.02)

I found it in render method of Hoomd tutorial notebooks.

Ok, cool! I can add a setter that is on/off (True/False) to visualize the box
