Abstract: Effective methods and algorithms are proposed for virtual 3D scene real-time illumination calculation with considering shadows from directed light sources. Methods are based on shadow map using. Blinn's advanced model taking into account shading and shadow density is introduced for surface illumination calculation of virtual object to be rendered. The creation process of shadow maps for directed light sources and real-time using of this maps are considered in detail.

Keywords: visualization, shadow maps, shadow simulation.
