Yup

Love it. I use it a lot.

I’m hoping you might add the ability to see the solid inside a sphere. To see the relationship of all the outer points touching the sphere’s extents. Thanks for considering.

beautiful

Beautifully rendered geometric shapes and concise descriptions of each. I love being able to easily turn and rotate each shape to see it from every angle and marvel at its perfection and finally spinning them endlessly til we both collapse, fully satisfied, to enjoy the after-glow of our geogasm :D

Очень хорошее приложение.

За 15₽ получаешь большую базу объемных фигур. Очень просто приложение в использовании. Спасибо разработчику!

Still great, still hoping for more!

Lovely app for what it does and for the price. Mostly at this point a visualisation aid. Apps like these are still rare and increasingly in demand. I would be happy to pay more for more options.

FAQ

What is iCrosss?

iCrosss is an educational application designed to help users learn solid geometry in an engaging way. It provides interactive 3D models of various polyhedra, allowing users to explore their shapes and generate cross-sections.

How do I create a cross-section in iCrosss?

To create a cross-section, you define a plane by tapping three points on the faces of a polyhedron. The application then generates and displays the resulting cross-section.

What types of polyhedra are supported?

The application supports a wide range of polyhedra, including regular polyhedra (Platonic solids), pyramids, prisms, anti-prisms, Archimedean solids, and their duals.

Is iCrosss free to use?

Yes, iCrosss is a free application. It does not feature in-app purchases or advertisements, allowing for an uninterrupted learning experience.

What are the different viewing modes available?

iCrosss offers several viewing modes to enhance the cross-section experience. These include a standard 3D mode, Épure mode (three projections), and a 3D cut mode which allows you to work with one of the two solid pieces after a cross-section is made.
