基本3D 繪圖引擎使用-Z 排序演算法

Abstract

The object of this project is to create and test a simple graphics engine. What this engine does is read a 3D ASCII model description file, and given the provided information render the model onto the screen, and also provide simple transformation options. At the heart of this graphics engine is the Z-Sort algorithm, which takes care of the order in which the polygons and drawing lines appear on the screen. During the making of this engine there are a lot of computer graphics fundamentals and techniques that we can learn from here. So, basically this engine demonstrates the usage of a few of these basic principles. My project is divided into six parts: Chapter 1 Discuss my motivation and goals for this project Chapter 2 Introduce the overall architecture and structure of the graphics engine. Chapter 3 Discuss the .ASC (ASCII 3D model description) file and its underlying composition. Chapter 4 Discuss vertex and matrix operations required for polygon transformation. Chapter 5 Discuss Visible Surface Determination. Chapter 6 Testing the engine and various results.
