992年7月，SGI公司首次发布了作为三维图形编程接口的OpenGL。目前它已成为国际上通用的开放式三维图形标准。它被集成到Unix、Windows NT 4.0、Windows 98等窗口系统中。各种游戏加速卡、专用加速部件都能不同程度地提高OpenGL程序的运行性能。OpenGL是一个图形硬件的软件接口（"GL"即Graphics Library）。图形程序员可以利用它提供的接口函数设计高品质的三维彩色图像所需的对象和操作。-992, in July, SGI has announced the first as three-dimensional graphics programming interface OpenGL. Currently, it has become common on the open 3D graphics standard. It was integrated into the Unix, Windows NT 4.0, Windows 98, such as window systems. Games Accelerator, dedicated components can speed up the different levels to improve the functioning of OpenGL performance. OpenGL graphics hardware is a software interface ( "GL" that the Graphics Library). Graphics programmer can use it for the interface design function of high-quality three-dimensional color images of objects and operations.

Raytracing example implement a basic ray-tracer and render a simple scene using ray casting and local shading. The starter code sets up a scene comprising of an ellipsoid and a plane, being illuminated by a point light source. Your job is to render the scene by implementing code fragments required for object intersections and Phong shading.
