Swinging Pendulum

About oscillations in sine rythm.

Swinging Pendulum:
For a cyclic animation we need only to calculate the images of one single oscillation!
The maximal angle of deflection multiplied by sin(clock*2*pi) leads to the actual angle of deflection at the time "clock" (Note: The sine function in POV-Ray needs the angle in radians values (2*pi = 360 degrees)!):

#declare Amplitude = 40; object { Pendula rotate <0,0,Amplitude*sin( clock*2*pi)> translate<0,2.15,0> } //---------------------------- end

scene description for POV-Ray:
"pendula1.ini" and
"pendula1.pov"
