Hey all,
Well basically I have created a scene with an object (like a fan) in it, but
what I am trying to do is actually rotate the object around quite quickly so it
looks like its creating a gust of wind. All i need to know is how to do the
rotating business?? I mean....I have tried rotating it with the clock variable
in the x, or the y, or the z axis...but it just moves the head of the object
around the screen...instead of what i want (making it rotate around and around
on the spot)!
Does anyone have any ideas!?!?
Regards,

Rotations are around the origin of the scene. POV-Ray has no idea what
the "center of the object" is. You need to rotate the object before
moving it. Keep it centered at the origin, rotate it, *then* move it to
the place you want it on the scene.

Translate the fan to the center of the scene, rotate it there, and then
translate it back.If it's supposed to rotate on the X axis, use rotate
x*clock*10. If it's the Z axis you need to rotate it around, use rotate
z*clock*10. If it's too slow (I doubt it will be too slow, but just in case)
change 10 to 20 or 50, maybe even 100.
