Hi easylin,
 Quote: can K3DSurf only plot explicit function?

K3DSurf can also plot implicit function (ie: f(x,y,z) = 0) which are more powerful than the explicit one . I'm not sure if that respond to your question, if not give me an example of function that you want to test with K3DSurf.
 Quote: can K3DSurf plot also scattered points data?

Right now, K3DSurf can only draw a filled surface or a mesh of lines. It's quite easy to implement this feature so I'll probably add it in the next release . Unfortunately, K3DSurf use only mathematical function as "input data" so to draw a set of data points defined by there 3D coordinates, you probably need a scientific program like GnuPlot , labplot or Qtiplot.
Hope this can help.

For example try: ((x-1)^2+(y-1)^2+(z-1)^2-0.003)*(x+y+z) are one "point", and one plane. (only will be have careful with intervals of of definition of x,y,z all between (-2, 2) and work with good grid resolution) (congratulations people of K3dsurf!) Edú (can I make to surfaces particular movements of morphings?) (sorry because my english in not good enougth)
