Positioning objects on a z radius evenly

Question

I'm useing papervision3d
And I have 8 objects/spheres and will be adding more
objects/spheres later
I was wondering if anyone knows a formula to position any
number of objects evenly on a z radius
any help will be greatly appreciated, sincerely newwave
here is what I have tried, as is only 4 objects/spheres are
visible on stage, due to overlapping
[code]
var M1:MaterialObject3D = new FlatShadeMaterial(light,
0xFF0000, 0xFFCC99);
obj1 = new Sphere(M1, 50, 10, 10);
obj1.x = -ORBITAL_RADIUS;
obj2 = new Sphere(M1, 50, 10, 10);
obj2.x = ORBITAL_RADIUS;
obj3 = new Sphere(M1, 50, 10, 10);
obj3.z = -ORBITAL_RADIUS;
obj4 = new Sphere(M1, 50, 10, 10);
obj4.z = ORBITAL_RADIUS;
obj5 = new Sphere(M1, 50, 10, 10);
obj5.z = -ORBITAL_RADIUS;
obj6 = new Sphere(M1, 50, 10, 10);
obj6.z = ORBITAL_RADIUS;
obj7 = new Sphere(M1, 50, 10, 10);
obj7.z = -ORBITAL_RADIUS;
obj8 = new Sphere(M1, 50, 10, 10);
obj8.z = ORBITAL_RADIUS;

Answer 1

interesting! lol ;)
well i'm not certain about the math on the z axis but it
'should' be similar in calc to a normal circular calc - you might
try reversing the cos, sin on each line. but the 'real' funny thing
is the grouping, but part of the issue here is the assignment of
the angle to 3 - the above formula divides degrees of rotation (eg.
360) by the quantity of object positions so you really need to have
that in there. but in hindsight you may want to increment the angle
within the array because in this way it will result in rotations
all the way through the circumference - so try this:
private static const ORBITAL_RADIUS:Number = 300;
private var angle:Number = 0;
var M1:MaterialObject3D = new FlatShadeMaterial(light,
0xFF0000, 0xFFCC99);
for(var i=0; i<8; i++) {
this['obj'+i] = new Sphere(M1, 50, 10, 10);
this['obj'+i].x = ORBITAL_RADIUS * Math.cos(angle);
this['obj'+i].z = ORBITAL_RADIUS * Math.sin(angle);
angle += (360 / 8) * Math.PI / 180;
that should do it ;)
