APPLICATION OF NATURAL AND ARTIFICIAL LIGHTING AND TRACING BY RAYS IN THREE-DIMENSIONAL MODELING

The article shows the use of visualization of three-dimensional objects, gives examples of creating models, using lighting realistic images using rendering with improved lighting. Computer graphics are of practical interest, as there is the possibility of obtaining realistic images. In computer graphics, a sufficiently fast “rasterization” technique was used, allowing displaying three-dimensional objects on a two-dimensional screen. In normal rasterization, objects in the scene are most often created from a special grid of triangles -polygons that intersect with each other. Despite the simpler technology compared to ray tracing, rasterization is difficult from a computer-processing point of view. Therefore, the most effective is the use of raytracing in the processing of models. Raytracing works differently. Tracing tracks the path of each light beam through all the pixels on a two-dimensional display to 3D models. Thanks to this, developers can achieve better lighting quality and different lighting effects. The basic principles ofthis theory are reflected in the article and a specific example of application is given. The difference of the processed image of a fragment of video material with respect to the original one is demonstrated. The practical use of the ray tracing method, its principles of construction and implementation are shown. In the process ofpreparing the work, a model of the room design was created, using the principles of constructing shadows and ray tracing. The study of the technological capabilities of computer graphics involves the use of raytracing and scenes with better lighting in modern cinema and animation. At the same time, the beam is reflectedfrom the surfaces ог passes through several objects before reaching the light source. This material is of interest to users, as researchers have the opportunity to obtain realistic images, build and run a 3D model of the object.
