First simulation is about shadows. I could test with maya lighting and renderer. At first, the basic shape sphere is used in test. And the lighting place and number are changed in each time. I focus on the shadow changing of shape, opacity and overlap.
I tested for many situation and I need the shape test for more realistic situation. So, the object is changed into human shape and the wall is added in simulation dark room. Especially, I was interested in projecting to wall directly from the bottom of floor. It seems like alter-ego in real life.
