Development of Light System for 2D Objects with Unity Engine

The present paper describes development of light system for 2D objects with Unity Game Engine. System functions and requirements are based on analysis of existing solutions. In the framework of the project custom light sources, system for shadow casting and shadow receiving were implemented. System for calculating shadows of the given shape was developed for visualization of unseen in 2D space object surfaces. Project results are presented as Unity Editor extension that does not require additional plug-ins. Public class methods and attributes are described in user documentation. The paper includes seven sections: introduction to the study, professional significance, goals and objectives, existing analogues review, system components description, system realization with Unity and conclusion. The results are reported in the narrative text and tables with graphical illustrations. The appendix includes source code of the developed light system components using C# and Cg programming languages.
