3D: Intersected volume

Axcel shared this question 2 months ago

Answered

Hi everyone,

is there a way to show the intersected volume of two quadrics (e.g. Sphere and Cylinder)? It would be perfect if GeoGebra would create another quadric as a seperate object.

If this currently cannot be done, is there any plan to implement this in the future?

Thanks and kind regards

Hi,

Can you please post a ggb file example with cylinder and sphere you would like to intersect? Thanks!

Yes, sure... :-)

Here is an example of an intersection of a sphere with a cylinder.

Thanks and kind regards

Wow, very impressive! As I see it, you are creating the illusion of intersecting the volumes by splitting them up in simpler sub-surfaces which can be described mathematically by a function graph involving parameters which are linked to sliders. This is going to make my task quite complicated. I think I will just wait for a future version where it will be as simple as Intersect(Sphere,Cylinder) Let's all hope that this will not be in the too far distant future...

Cheers

Why ?

because you don't want to use your brain ?!

Why do you want, that internet can be resolve your problem ?

Please think for yourself.

It will be more interesting for you.

algunas curvas siguen dejando un falso rastro al mover los deslizadores. este bug fue comunicado pero parece no resuelto

Sorry, we don't have any plans for that
