A point source emits light at a circular disc (thickness negligible), and a shadow is left on a wall (xy plane) behind and parallel to the disc. the z component of distance between the point source and the disc is 'a' units. When light falls upon sphere, shadow is cast on screen. what we see is that: spherical object is of three dimensions. but cast two dimensional shadows.

Shadows Of Circles Smithsonian Photo Contest Smithsonian Magazine A point source emits light at a circular disc (thickness negligible), and a shadow is left on a wall (xy plane) behind and parallel to the disc. the z component of distance between the point source and the disc is 'a' units. When light falls upon sphere, shadow is cast on screen. what we see is that: spherical object is of three dimensions. but cast two dimensional shadows. In the left diagram, a vertical object of height $h$ sits normal to the surface of the sphere (reduced to a circle for simplicity). incoming light casts a shadow (beneath $\lambda$) at an angle $\vartheta$ from the surface of the object.

In general, we cannot determine a convex body from the set of shadows (if we don't know the correspondence between shadows and directions of projections). take a unit ball and cut off three identical tiny caps whose centers form a regular triangle on the sphere and are not on one great circle. What you’re looking for are blob shadows, but if you must use shadow mapping, you could to the following: create a sphere on each object set it to cast shadows >shadows only.
