In the article, a new light lock shock and barrel art reflectance model is proposed.The model is based on the modified cosine-quadratic bidirectional reflectance distribution function.The concept of bidirectional reflectance distribution function is analyzed.The disadvantages of existing physically accurate and empirical bidirectional reflectance distribution functions, including classical cosine-quadratic function, are discussed.The necessity of new empirical distributive functions development is justified.

The comparison of double dorisvale station for sale integrals of hemispherical reflectivity of reference Blinn function and classical cosine-quadratic function is provided.Based on the comparison, the new expression of cosine-quadratic distributive function calculation is obtained.The proposed expression makes it possible to significantly increase the accuracy of glare epicentre reproduction and is intended for use in highly productive three-dimensional rendering systems.
