计算机图形学大作业

一、实验要求

绘制一个简单的三维场景，可以是室内：卧室，办公室，教室，也可以是室外：运动场，公园等，加上光照效果，简单的纹理映射，透视投影；不能过于简单；可以加动画、鼠标和键盘交互。

上交材料： project和word文档（具体内容展示，思路和心得）

二、实验思路

首先初始化窗口，定义摄像机坐标与视口坐标，利用实验二的知识内容绘制三维立体模型，定义每一个模型的坐标值以及利用变换函数实现相对位置的放置；利用实验三中的知识给整个场景进行灯光的设置；然后使用实验四中的代码实现模型材质的纹理贴图；最后进行鼠标与键盘的交互，实现鼠标可以控制摄像机的高度以及键盘的上下左右实现摄像机的移动。

四、实验结果与心得

本次作业，对模型的坐标值的计算进行放置比较复杂，其次还有赋予材质贴图时也出现了各式各样的毛病，比如进行一个贴图的赋予时，就会给整个场景赋予相同的贴图；之后进行修改代码，最后可以给每一个模型进行赋予材质，但也只有几个面的贴图铺张是正确的显示，目前尚未解决。通过此次大作业，对图形学中三维可编程绘制流水线已经有部分的了解与学习。虽然过程中有各式各样的困难但也是逐个击破，对今后的学习也是有了较大的帮助。
