Compared with the first one (Episode #1:
massPointtool), this layout has two types of points:
massPoints, gravity sensitive and draggable.
mathPoints. They are not gravity sensitive nor draggable. They can be defined as satellites of the
mathPoint is a dynamical point, not a physical object like
massPoints . The
mathPoint tool is essentially a drawing and rendering tool and belongs to pure geometry.
mathPoint can be located:
- anywhere on a line or a curve passing through two
mathPointcan also be implemented with a movement along its belonging line or curve.
- at any point of an area defined by three or four
- at the exact intersection of two lines, each of these lines passing through two
mathPoint is not draggable by mouse or touch event. It depends entirely on its belonging
