vertcies: a 3D model is basically made up of points, the wireframe lines that connect them to each other, and then faces that give the object a suface. Vertices are the points. magnet: a tool in Poser and in many 3D modelling programs that allow you to select a certain area of your mesh and then push and pull that area of the model around. Points (or vertices) near the center of that area will move more than the points at the edges of the area. geometry: a general term for the specific shape of a 3d model. Spline: a regular line goes from point A to B and then from B to C. A spline moves in a curve from point A, arcing through point B to point C. NURBS: Non-Uniform Rational(?) B-Splines (or something like that). This is a function of many 3d modelling programs that allows you to create a smooth, high-resolution mesh out of a low-resolution mesh, using the same kind of math that splines are based on. It's a great tool for creating organic models as well as curvy non-organics (such as a sportscar). Hope this helps.
