Our collection of DKM is set to expand. Some are already developed, others are under development or in the project stage. Once the development cost of a DKM is funded, it is placed under the LGPL license; otherwise, it is under the CC by-nc-nd license.
Interactive geometry
With this model, the user constructs interactive geometric figures. The resulting figures can then be deformed with the mouse. Using scripts, we create a very wide variety of figures, some of them very complex when loops or recursion are implemented. This DKM will be an adaptation of Dr. Geo, for joint use as a DKM module and standalone application. | canvas r f u | canvas := DrGeoSketch new axesOn scale: 500. r := canvas float: 2 at: 0 @ -0.1 from: 0 to: 4 name: 'r' showValue: true. f := [ :x | r value * x * (1 - x) ]. canvas ray: 0@0 to: 1@1. canvas plot: f from: 0 to: 1. u := canvas pointOnLine: (canvas segment: 0@0 to: 1@0) hide at: 0.2. 100 timesRepeat: [ | v | v := canvas " v sequence term " point: [ :previous | previous point x @ (f value: previous point x) ] parent: u. canvas segment: u to: v. u := canvas " u is a point on the Ray (0,0) (1,1) " point: [:previous | previous point y @ previous point y ] parent: v. v hide. u hide. canvas segment: u to: v. v := u]
