Hi,
In an e-mail some time ago (below) you gave a formula that supposedly
converts between image plate and pixel coordinates. I've tried to use
this to convert from VWorld to pixel coordinates:
// Convert p from VWorld to image plate coordinates
Point3d p = new Point3d(10.0, 10.0, 10.0);
Tranform3D t = new Transform3D();
getVworldToImagePlate(t);
t.transform(p);
// Then bung p through you formula
However, your formula does not take into account the z component of p
and so the final coordinates aren't where I want them to be. Any ideas?
Have I got the wrong idea by tring to use getVworldToImagePlate()?
Thanks,
Jon Beniston.
