Coloring of a closed area

John Andreasen shared this idea 3 years ago
Completed

I am fully aware of the fact, that this might be a little off topic, regarding to the nature of GeoGebra ;)


But it would be nice, if it were possible to colourize a closed area - something like this:


d6303dadbf6bd692f79bdd4dba4ba11e


to this...

If there is a solution, I will be very happy.

Just find the parametric equation of your figure and then change the color and choose opacity equal to 100.

Hola


La verdad no tengo idea. Recuerdo haber puesto solo el link y ahora que veo aparece así. Es un misterio.


Por cierto en la versión del teléfono aparece solamente el link. No aparece el iframe. Qué raro.


Saludos

Another interesting curve is this one:

  1. Curve[(1 / 2 round(sin(3.2θ))² - 1 / 2 round(cos(3.2θ))² + 2.4asin(cos(3.2θ)); θ), θ, 0, 10π]

Kind regards

Thanks for the suggestions to the current drawing. It helped me in making the attached file.


But the idea is more general meant... It would be nice if it was possible to fill any closed area with a color ;)
