Нова архітектура програмної системи для високореалістичного та високопродуктивного рендерингу 3D-зображень

Abstract

A new architecture of a 3D rendering system is proposed in the article. The advantages and disadvantages of existing visualization systems, such as Eevee, Cycles, BRDF Explorer, Mitsuba, Idx3d, V-Ray, RenderMan, UnrealEngine, are analyzed. The need to develop a new architecture of a rendering system is justified. The features of the main components of the proposed architecture are considered. The subsystems of input data processing, geometric transformations, and determination of the optimal number of triangles are described, which ensure highly efficient preparation of the scene for visualization. The features of implementing the concept of hybrid rendering based on a combination of rasterization, ray tracing, and neural rendering subsystems are investigated. Particular attention is paid to architectural blocks based on the proposed reflectance models, vector normalization methods, and intelligent 3D rendering methods, the integration of which provides increased productivity and realism of image formation in real time. A structural scheme of the proposed 3D rendering system is created.
