What makes shadow fuzzy?
The blurry edges of everyday shadows are caused by the light sources being extended objects. Light from different parts of the source are able to travel into the shadow area because they emanate from different points in space. The darker, inner part of the shadow where no light can reach is called the “umbra”.
How can a shadow change its shape?
How can you vary the size of a shadow? The closer an object is to the light source, the larger the shadow it casts. This is because an object closer to the source will block a larger area of the light, increasing its shadow size.
Can you use shadow mapping for multiple lights?
Using multiple lights with shadow mapping is an easy extension of the basic shadow mapping technique. Instead of rendering just a single depth map from one light’s perspective you now render a depth map for each light in the scene.
Do you get two shadows from two lights?
Yes, just as your husband said, the two shadows come from two lights. The two shodows will pretty much overlap when the two lights are the same direction from you. As you walk, the shadow from the closer light will change its angle faster than the one from the farther light.
How do you get two shadows from one object?
Check out the other questions and answers on this topic–they might be interesting to you. To get two shadows from one object, you need two light sources; either two real sources of light, or effectively two sources because of some kind of reflection. In this case, since you were in the bathroom, I wonder if there was a mirror nearby?
Why does a mirror create a second Shadow?
The reflection of the nightlight from a mirror could act as a second light source, creating a second shadow. I would guess that the darker shadow just happened to be in a place where there was a little less background light, making it appear darker.
