The paper is devoted to the derivation of a bidirectional distribution function for crystals, which specifies all outgoing rays for a ray coming to the boundary of two transparent crystalline media with different optical properties, i.e., a particular mineral, directions of optical axes if they exist, and other features. A local model of interaction based(More)
An approach to verification and validation of algorithms that render transparent objects (media) is described. Rendering of transparent optically isotropic objects has been studied extensively. However, the papers devoted to optically anisotropic objects are few in number. The main goal of the present paper is to suggest a collaboration in creating and(More)
We analyzed the problem of mathematical modeling and computer simulation of nonlinear controlled dynamical systems usually described by differential-algebraic equations. The problem is proposed to be solved in the framework of the semi-empirical approach combining theoretical knowledge for the plant with training tools of artificial neural network field.(More)
This paper is devoted to the problem of photorealistic rendering of optically active crystals. Optical activity (rotation) is turning of the polarization plane of linearly polarized light while it propagates through optically active medium. Quartz is one of well-known optically active crystals. It is an optically uniaxial crystal; however, there are(More)
