| Abstract: |
The solution simulation of the global illumination equation by the local estimation of the Monte Carlo method is analyzed in the paper. Local estimation methods allow implementing simulation at the arbitrary reflectance law and directly calculating luminance in every point and direction of 3D scene. The local estimations are more effective methods than straight modeling. Their usage does not demand the mesh creation for the illumination map formation. The possibility of 3D object representation on the basis of the spherical harmonics is also considered in the paper. The spectral representation possesses the essential advantages for some object classes. The algorithms of the local and double local estimation with the usage of object representation on the basis of the spherical harmonics are implemented in the framework of paper. This algorithm allow realizing the physically adequate modeling of the global illumination equation solution and calculating the luminance directly that opens new horizons both in the photometry and computer graphics. |
