基于Ray Tracing的《计算机图形学》实验教学研究

Research of Computer Graphics Experiment Teaching Based on Ray Tracing

真实感图形学是计算机图形学的重要研究方向之一,主要研究如何使用计算机模拟真实场景,生成真假难辨的画面。但是,目前高校《计算机图形学》的教学内容常以简单画面的绘制为主,忽略了有关真实感绘制的内容。文中针对真实感图形学,根据真实感绘制中常用的光线跟踪算法设计教学实验,以加强学生对真实感图形学的了解。实验涉及场景光照明模型与几何求交等知识,可以培养学生研究问题和解决问题的能力。

Realistic graphics is an important research direction of computer graphics, which tries to simulate the real world to generate realistic pictures by computer. However, current teaching of computer graphics usually focuses on the rendering of simple images, igno- ring the introduction of realistic graphics. This paper proposes a teaching experiment based on ray tracing to make the students under- stand realistic graphics better. The experiment will use illumination models, intersection algorithm and so on, which can improve students＇ ability to study and solve problems.
