Introduction to Rendering Techniques
Definition of Rendering in 3D Graphics
Rendering in 3D graphics refers to the process of generating a two-dimensional image from a three-dimensional model. This involves the computation of light, color, and texture to create a realistic representation of the scene. Rendering techniques can be categorized into several types, each with its own advantages and applications.
Common rendering techniques include rasterization, ray tracing, and radiosity. Rasterization is the most widely used method in real-time applications, as it converts 3D models into pixels quickly.
