Position a sphere in 3d space (Read 654 times)

Position a sphere in 3d space
Mar 3rd, 2009, 7:00pm  
What is the best way to position a sphere in 3d space?  Lines give you a nice x,y,z - 2d objects give you an x,y - but spheres... just radius.  

So I've been using a transform, along with pop,push matrix.  Is this the best way to do this.

 stroke(126, 50);
 line(0, 0, 0, 100, 0, 0);
 line(0, 0, 0, 0, 100, 0);
 line(0, 0, 0, 0, 0, 100);
 noStroke();
 translate(0, 0, 0);
 fill(255, 0, 160, 50);
 sphere(10);
 sphereDetail(20);
 pushMatrix();
 translate(100,0,0);
 sphere(10);
 popMatrix();
 pushMatrix();
 translate(0,100,0);
 sphere(10);
 popMatrix();
 translate(0,0,100);
 sphere(10);

Yup, translate combined with push/popMatrix is the way to do it.
