Design and Implementation of WebGL Model Rendering Engine

Abstract

This thesis conducts an in-depth study and implements a model rendering engine based on WebGL. It elaborates on the basic concepts, characteristics of WebGL, and its application prospects in the field of real-time graphics rendering. The implementation methods are discussed, and a design scheme of the model rendering engine based on WebGL is proposed. When introducing the background and basic principles of WebGL, it is pointed out that it is a technology for high-performance graphics rendering in the browser using JavaScript. Based on the OpenGL ES 2.0 standard, it is achieved by embedding its context in the HTML5 Canvas element, and has advantages such as cross-platform, high performance, easy learning and use. In addition, the design scheme of this engine is proposed, including key technologies such as model loading and lighting calculation. Common rendering engine frameworks and tools are also introduced to help developers efficiently build WebGL applications.
