I'm using Unity to build up the virtual environment and the HTC Vive to represent the environment itself. I'm also using Blender to create the 3D files and texture mapping. Overall, it's more involved than I had originally thought it would be. Luckily, I'm stubborn and have somehow made it work.

It may not look like much, but it's a working environment. It's still a work-in-progress, but I wanted to show it off. The barbell in the upper left on the rack is interactable with the handheld controllers of the Vive. Each barbell that will be used is coded with the variable representing its weight. This will allow the PC to do the required math for the torque values and send the associated brake positions.

In future iterations, I would like to have background individuals walking around, but at this point in time, that is not happening. For now, I'll finish populating the dumbbells in the gym and optimize for rapid calculations.
