3D Geometry is an app designed for observing and manipulating geometrical figures in three dimensional space.
There are many types of three-dimensional shapes beyond the spheres and squares you are surely familiar with. In this app you'll learn about polyhedra; three-dimensional shapes whose faces are polygons — three special types of polyhedra in particular: prisms, pyramids and platonics.
Observe prisms, pyramids, truncated pyramids, and platonics, adjust rotation and positioning with your hands via the Leap Motion Controller.
Flatten the shapes by spinning your finger in a circle to see how they look in 2 dimensions.
Paint a color on each face with one finger hover. It's useful when teaching in classrooms.
Learn how to calculate surface area and volume for common 3d shapes.
Study how many vertices, lines and faces are in a shape.
