Need an order for the lines and planes / Need to find a more efficient object and angle for the projection. I guess that’s why most people use tetrahedron for this type of project. I might try tetrahedron asap. This doesn’t look good, but depending on the movement of the animation you will found some interesting perspectives such as mirror illusion or something like that. I thought it wouldn’t work at all before, but either the movement of the animation or the angle of the tangible object might be applied in a interesting way. Also, the location of the projector is just on my desk and next the computer. The location is totally comfortable working on this, but I might try to place various locations of the projector and different objects as well, which will give various results in terms of the relationship between the light and angle of the object.
