Can shadows be curved?
Curved shadows are physically possible when cast onto a curved surface. Webpages are flat. It's also possible using orthographic projection. If the paper is curved outward toward the viewer and against a flat surface, the paper will still appear rectilinear.
What do you need to make a shadow?
For a shadow to be formed an object must block light. The object must be opaque or translucent to make a shadow. A transparent object will not make any shadow, as light passes straight through transparent objects.
How do shadows work?
Shadows are formed when an opaque object or material is placed in the path of rays of light. The opaque material does not let the light pass through it. The light rays that go past the edges of the material make an outline for the shadow.
