week 28.06.2010-04.07.2010

Finished the new algorithm. Tested the algorithm and fixed hopefully most of the errors. Refined some parts of the algorithm, works faster and more accurate now. Still problems with curves having boundaries or singularities.

week 21.06.2010-27.06.2010

Started implementing another algorithm. The goal is to get an algorithm which works on one time differentiable curves by first getting a point on the curve and then trace it down with the gradient.

week 14.06.2010-20.06.2010

Implemented the AlgoDependentImplicitPoly so the implicit polynomial equation can be changed dynamically. (e.g. per Slider) Did some reasearch about other algorithms, because the first ones min/max-function discribed last week is only working for polynomials.

week 07.06.2010-13.06.2010

Still worked on the algorithm, had some problems with the min/max-function which should dicide whether the polynomial can have roots inside a given rectangle. This part worked at last. Tried to improve the performance of the algorithm, without much success.

week 31.05.2010-06.06.2010

Created needed files, created classes GeoImplicitPoly and DrawImplicitPoly, changes to GeoElement, Kernel and AlgebraProcessor. Implemented needed function bodies, such that the Objects are displayed correct in algebra-view and so on. Started implementing a subdivision algorithm for implicit polynomial equations.

week 24.05.2010-30.05.2010

Started the work with GeoGebra. Tried to get into the structure of the code. Find out how all this cool things work. :) Organized wiki, started reading (Especially about subdivision algorithms, also something about parametrization)
