What is Pendulum Wave

What is Pendulum Wave • Many different period pendulums consist of Pendulum Waves. • The length of each pendulum and gravity determine the period of each pendulum. • By varying the length of a series of pendulums, some very interesting patterns emerge.

Environment • Textures make experiment equipment more authentic. (the board the lamp and the bar ) • Also lighting and material parameters make the pendulum looks more heavy , like the real ones. • Yellow: gold • red: ruby • white: pearl • orange: copper (According to Open. GL Material)

Result

Future Work • We need more accurate calculation, because after the whole pendulum waves loop a few cycles, the displacement of some pendulum strayed out a little bit. • GPU programming maybe suited to this simulation of Pendulum waves, because we can take apart these 12 pendulum waves as parallel process working simultaneously.
