Pardon my ignorance, but a heightfield would seem to imply a
two-dimensional surface with an array of height data e.g. fz(x,y). What I
have is actually a four dimensional set of data Fintensity(x,y,z).
(actually the data is complex so the data is five dimensional) For the
moment I just want to plot the intensity (perhaps the phase as color
later) for a mesh of points in three-space. I have just played around
with a glow demo in MacMegaPOV and it seems like a possible solution -
next would be to set up a camera and stroll around the object to generate
an animation (e.g. quicktime or such). Another possible solution would
seem to be to generate an isosurface from the numerical data. This way the
symmetry of the data would be clearer - perhaps a combination of two such
techniques would be best. Someone must have done something like this
before and have an opinion -- e.g. plotting temperature data in three
space or some such. Any opinions are more than welcome. I definately do
*not* know what I am doing with POV so any opinions are most welcome.
