Scalar plot in 3D

Hi everyone! I am still struggling with my "rendering hassles" :) I don't really know how to implement this in Mathematica, although the idea is quite simple. I have a list of points in 3D, their relative scalar value, and I'd like to have them nicely rendered on the domain on which they are defined. In other words, I have sampled a scalar field on a torus, and I'd like to plot its value (by hue or any other color means). Simple as it is, I cannot figure how to obtain this! Basically, I know the torus' radii (rMIN and rMAX), and I have my good vectors: coords = {{x1, y1, z1}, {x2, y2, z2}, ...} values = {v1, v2, ...} Is there anyone who can help me with this? I have seen ListVectorPlot3D, but it won't show in the plot the domain itself (so arrows laying on a torus), and ineed, it requires a vector field. Although I can fake a vector field, I'd like something more "visually appealing"! :) Thanks to anyone! Franco
