Hello everyone,
I am practising on mechsim and gravity, what I am trying to do is to drop a
ball from a height (on Y axis) and let it bounce on the floor. X is
constant, Z is constant and Y varies along time.
I have seen the tutorial02.pov for this, but I dont' really understand the
way world's camera and XYZ coordinates are defined and used. In that
example it defines gravity <0, 0, -9.81>, where it puts the gravity force
on Z axis instead of Y axis.
Could you provide some help on this.
many thanks,
dimitris.

The mechsim tutorial and sample scenes use a z=up coordinate system.
Mechsim works for both this and the standard POV-Ray system.
