Re: [OpenMap Users] 3D in OpenMap?

Good Morning Tore,

        The 3D code performs more many floating point operations per second
than the OpenMap code because the 3D code takes advantage of the
computer's 3D graphics processing pipeline. However, the speed of the
pipeline comes at the cost of generality. If you can express your
problem in terms of vertices and transform matrices then some Java 3D
or OpenGL code and a graphics card can work wonders. But that often
isn't possible. If, for example, you have some geodetic coordinates
you need to apply a Mercador projection to I don't see how you could
write the code in Java 3D to do the computation.
        It is possible to do everything in a 3D framework but that is usually
considered more complicated that a combined 2D/3D solution.
