Use mouse to rotate the object. Also an example of the use of Out-of-stage Mouse Position: https://scratch.mit.edu/projects/368646517/ (So rotation still works even if the mouse is moving out of the canvas)
Orthographic projection is used for the project. Due to optical illusion, the object may be wrongly interpreted by the brain (because of the projection method and that the solid is not filled) (To modify the objects, just change the contents of the five arrays, E1, E2, X, Y and Z, where X, Y, Z are the coordinates of each point, and E1 and E2 are the starting point and ending point of the edges respectively) Tag: Polyhedron Tetrahedron Hexahedron Cube Octahedron Dodecahedron Icosahedron
