Light and Shadows: Object Projection and Shadow Construction

This lecture explores the concept of projecting shadows from an object illuminated by a point or parallel light source. The instructor guides the audience through the process of constructing shadows on both the ground and the wall, using a pyramid as an example. The lecture delves into the importance of determining the path of light rays and understanding the orientation of object surfaces to differentiate between the object's own shadow and the cast shadow. Various construction techniques are demonstrated, emphasizing the significance of considering the orientation of object vertices in relation to the projected shadows. The lecture concludes with a discussion on the proper orientation of object faces in relation to their cast shadows, highlighting the complexities involved in shadow projection and construction.
