Class Detail
Glider(z_,x_,y_,GlideObject)
A glider is a point which lives on another geometric element like a line, circle, curve, turtle.
// Create a glider with user defined coordinates. If the coordinates are not on // the circle (like in this case) the point will be projected onto the circle. var p1 = board.create('point', [2.0, 2.0]); var c1 = board.create('circle', [p1, 2.0]); var p2 = board.create('glider', [2.0, 1.5, c1]);
// Create a glider with default coordinates (1,0,0). Same premises as above. var p1 = board.create('point', [2.0, 2.0]); var c1 = board.create('circle', [p1, 2.0]); var p2 = board.create('glider', [c1]);
- Parameters:
- {number_number_number_JXG.GeometryElement} z_,x_,y_,GlideObject
- Parent elements can be two or three elements of type number and the object the glider lives on. The coordinates are completely optional. If not given the origin is used. If you provide two numbers for coordinates they will be interpreted as affine euclidean coordinates, otherwise they will be interpreted as homogeneous coordinates. In any case the point will be projected on the glide object.
- Throws:
- {Exception}
- If the element cannot be constructed with the given parent objects an exception is thrown.

{JXG.GeometryElement}
slideObject
When used as a glider this member stores the object, where to glide on. To set the object to glide on use the method
JXG.Point#makeGlider and DO NOT set this property directly as it will break the dependency tree.
TODO: Requires renaming to glideObject
Method Detail
startAnimation(direction, stepCount)
Animate the point.
- Parameters:
- {number} direction
- The direction the glider is animated. Can be +1 or -1.
- {number} stepCount
- The number of steps.
- See:
- Glider#stopAnimation
stopAnimation()
Stop animation.
