Sažetak

Shadows provide important visual hints about the spatial relationship between objects. Shadow volumes are one way to generate sophisticated shadows for use in real time environments. This paper focuses on the geometric aspects which are involved in the creation of the shadow volume. Speed up techniques like shaders and dual space approaches for silhouette determination are discussed. Finally the application of the described methods in a software for shadow profile calculation is explained.
