I am playing around with lightwave and I need help. There is something very odd thats going on and I think it has to do with my equation.
First of all I know that the equation for drawing a circle is f(x) == sqrt(r^2 - x^2) . The position of x changes frame by frame in a linear fassion. (ex frame1:x = 1; frame2:x=2 and so-on) and I am making a circle using the X and Z axis.
[Camera.Position.Z] set to -sqrt(10^2 - [Camera.Position.X]^2)
Now here is the problem... the values keep getting screwed up some how... here is a picture of whats going on... The white line with the plusses is the camera path.
the x travels fine, but the z is doing something oquard... if anyone can see a flaw in my equation please pic it out...

Why not save yourself much grief and use the parametric representation of a circle (i.e., {x,z}={cos(t),sin(t)}; t in radians)? Your camera would move much more uniformly... and I do remember the last time I used LightWave that it supports parametrically-defined camera paths...
