Hello, I'm having trouble--I have a decent head model that I've imported into Solidworks, and I have a helmet and an HMD that goes on top of the head. I want to know what kind of obscuration the HMD poses to the user, so I am trying to put cameras at the eyes of the head, pointing them straight out. But I can't seem to configure the three parameters (theta, l, and h) to appropriately mock a human eye. One of my tests is if I can see the slope of the head's nose out of the corner of one "eye." Does anyone have any insight to how to best accomplish this?
