As for the visualization, it really depends on the type of data you have:
If it is height information over a 2D grid, a height_field object will
suffice...it takes an image as input and creates a surface where the
"height" of each point is determined by the brightness of the
corresponding point on the image.
If it is a mathematical function or a 3D voxel map, an isosurface is
perfect for it...you could also use the function as a density pattern
for media, so you don't get a surface but see the function as varying
densities in smoke or glowing gas. I'd recommend using emitting media,
at least at first...scattering media will be slower and harder to
control. Fog won't be useful for this.
If it is a collection of points...well, fitting a mesh to those points
would be difficult and probably not what you want. You might try a blob
object with a spherical component at the position of each point. You
could also use the blob pattern as a media density pattern...
If it is a mesh, you just need to convert it to something POV can read.
More specific information is needed...
I gather from your description that you're basically looking for a way toQuote:> I would like to find an aesthetically pleasing way to plot a 3D

Could one provide me an info or a routine for
drawing 3D vector fields? (with arrows in form of pyramids or cones)
