The CPAP machine, humidifier, water tank, and other components.
Part of the animation involved demonstrating different screens an animating ramp up screen, as well as various key-frame and blend shape animations to demonstrate assembly and use.
Wireframe of the CPAP and some of the parts, about 50,000 tris.
I modeled an animated this CPAP machine for a client's app. The animations demonstrate how the CPAP is assembled and used. I modeled and animated this in Maya, created PBR materials in Substance Painter (and Photoshop), and set up the file as a asset package in Unity (per my client's specifications.)
