== No mobile support == arrow keys to rotate the L-shape ws,ad,zx to move x,y,z of the L-shape note that the only thing this program draws is the outline of the cross sections, and it never draws the object body nor fills the cross sections. In Japan, finding or drawing the cross section of the given cube is a hotly asked question in junior high school entrance exams. Therefore, there have been several projects explaining on it. However, I thought their ways to get to the answer is not universal; i mean it's impossible draw the cross section of other solid figures like spheres and cones with their solutions. So, I made this. You can give this program any 3d-object you want (by editing 6 lists inside :D).
