Usage

The demo simulates one deformable armadillo mesh that is fixed at one hand and swings due to gravity.
Controls:

• Alt + Mouse: rotate the camera
• Ctrl + Mouse: zoom
• Shift + Mouse: move the camera
• Space: start / pause the simulation
• R: reset the simulation and print timings
• W: toggle wireframe rendering
