Re: [Jmol-developers] Povray -- transform

[pim s. <pim...@go...>]

Didn't check it yet in povray, but I think this goes in the right
direction, and most important, without having to convert to integer
coordinates at some point (ouch!):

  public void renderAtom(Atom atom, short colix) {
    Point3f point1 = new Point3f();
    String color = rgbFractionalFromColix(colix, ',');
    float r = atom.getMadAtom() / 2000f;
    // both arguments to transformPoint are float therefore:
    //   going from angstrom to floating point screen value (= using
perspective)
    viewer.transformPoint(atom,point1);
    // (float) is superfluous here then:
    float x = (float)point1.x;
    float y = (float)point1.y;
    float z = (float)point1.z;
    output.append("atom("+x+","+y+","+z+","+r+","+color+")\n");
    nBalls++;
  }
