Unless there is a new magic then it boils down to that. It glows or reflects or refracts depending upon what you tell it to do with the light you shine on it. It can respond to external or internal events as you choose. So far, you can compute however you can but to viz you seem to need at least one and typically in groups of 3 ccw to make a viz. So that is a pattern, compute bunches of stuff and produce interactive xyz viz for the feelings and wisdom then update the compute stuff, and so on. </p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Use the idea of a animating one of more xyz of a mesh independently of other xyz in the mesh. The mesh needs to be able to hang together given what you wish to do. If each displacement is fairly predicable and linear weighting then you can use the idea of a 3D weighted displacement vector applied independently to each of your points of interest. Each vector can be pointed where you wish and scaled 0 to full effect (all changeable at your will) to act upon the chosen points of your chosen mesh in the coordinate system of the mesh. </p><p class=MsoNormal><o:p> </o:p></p><ul style='margin-top:0in' type=disc><li class=MsoListParagraph style='margin-left:0in;mso-list:l1 level1 lfo2'>spherical coordinates</li></ul><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>I remember info about that in GeoSpatial</p><p class=MsoNormal>This sort of specialized Displacer is included in hanim browsers mainly to simplify and augment subtle mesh animation along with others styles, like using weighted joint rotations and coordinate interpolators.
