APPLYING THE REAL TIME SHADOWING METHOD FOR CREATING SOFT SHADOWS IN OPENGLKeywords: light source, OpenGL, penumbra, shadow, soft shadow, umbra Abstract: This paper presents a technique for rapidly generating and rendering of soft shadows on the scene. The method has the advantage of real-time creating of shadows which look more realistic than hard shadows and have high quality, also it has not high demands in resources. The main idea is to replace a complex light source with a collection of multiple point sources of light in order to decrease rendering time. The mathematic model, experiments, and comparison with similar techniques are given and described
