Contour Animation - Now Key Frames can remember coordinates of objects' nodes. This allows for the animating of polylines, curves, and profiles of 3D objects. GIF Frames and Movies - Animation frames can now be saved not only in BMP and JPEG formats, but also in GIF format; and the resultant movie can be either in AVI or in Animated GIF format. Support is also provided for such options as palette optimization, user defined colors count, dithering and transparency. Constrained Objects Support - Defined actors will take existing constraints into account when each of the frames is calculated. This makes it possible to create animations of cinematic schemes or Compound Profiles of 3D objects. By using the "SetVariable" command, it is also possible to change numeric values of the Constraint Manager variables. Part Tree Support- If an actor was used as an operand in the Part Tree, then when this actor is changed, the Part Tree will recalculate the resultant body, taking changes into account. New Commands - SetPropertyValue, SetVariable
