Real-time volume shadow using visible-non visible algorithm

Problem statement: Shadows are most important effect to make realistic games and visually appealing images, but they are poor in frame per second. Silhouette detection is most important phases to create real-time shadow. Approach: Present study describes a real-time shadow generated with volume shad...

Silhouette detection is most important phases to create real-time shadow. Approach: Present study describes a real-time shadow generated with volume shadow algorithm using Visible-Non Visible algorithm (VNV) in virtual environment illuminated by a movable light source to improve the frame per second. Silhouette detection that is most expensive part of shadow creation was described. Triangular method and VNV method were compared.

Results: The VNV algorithm increases the number of Frame Per Second (FPS) and as a result decreases the cost of implementation.

It is possible to use it in current commercial games or other virtual reality systems.
