Shadows

An example of the programme of the course Descriptive Geometry and Perspective is presented; an assignment on the topic of shadow. The object is presented via the method of orthogonal projection and is a cylindrically shaped bracket covered by a hexagonal plate. The assignment is to construct all the shadows of the object (the cylinder’s and plate’s shadow, the shadow of the object on the wall and the shadow of the plate on the cylinder) in parallel diagonal lighting. All necessary constructions are displayed using the same colour of various intensities and indicate the above mentioned types of shadows.
