Subject: circular motion of a shape using TranslateXYZ
To: gem-dev at iem.at.

Hi everyone,

This is my first post to the list so please bear with me.

I am trying to move  a shape (sphere, square, cube doesn't matter to much)
in a circle around a central point.  The Easiest way to do this is to use
Translate XYZ to move the shape for example 1 unit X,Y or Z and then use
rotateXYZ to rotate it.  Simple, except I would like to keep the shape
always pointing up, so that the texture that will be applied to the shape
will always be the correct way up.  For this I have decided to use just
TranslateXYZ.  I have attached how far I have got with this so far.  As you
can see the shape moves as in a square motion rather than a circular motion.


I am guessing I need to apply some maths to the numbers between the line
object and the Translate XYZ object, but everything I've  tried hasn't
worked.

Thanks in advance

Richard
