多面体VR

This teaching material displays a hand recognized by a smartphone camera on the VR screen. You can use this hand to perform various operations. The polyhedron can be reduced/enlarged, and rotated horizontally and vertically using each slider. Also, when you touch a vertex, edge, or face of the polyhedron with the recognized hand, the color changes, and the number of vertices, edges, and faces that have changed color is updated. When you press the reset button for each vertex, edge, or face, It returns to its original color and the number of vertices, edges, and faces becomes 0. You can change the displayed polyhedron using the buttons in the scroll view. A total of 20 polyhedra can be displayed, 5 regular polyhedra and 15 quasi-regular polyhedra.
