3D Graphics Engine
A software system that renders three-dimensional scenes into two-dimensional images in real-time through a pipeline of geometric transformations, rasterization, and shading operations.
Overview
A 3D graphics engine is a complex software framework that transforms mathematical representations of three-dimensional objects into visible images on a two-dimensional display. These engines form the cornerstone of modern real-time rendering systems and serve as the foundation for video game development, computer-aided design, and virtual reality applications.
