計算機圖形學大作業

一、實驗要求

繪制一個簡單的三維場景，可以是室內：臥室，辦公室，教室，也可以是室外：運動場，公園等，加上光照效果，簡單的紋理映射，透視投影；不能過于簡單；可以加動畫、鼠標和鍵盤交互。

??? 上交材料： project和word文檔（具體內容展示，思路和心得）

二、實驗思路

首先初始化窗口，定義攝像機坐標與視口坐標，利用實驗二的知識內容繪制三維立體模型，定義每一個模型的坐標值以及利用變換函數實現相對位置的放置；利用實驗三中的知識給整個場景進行燈光的設置；然后使用實驗四中的代碼實現模型材質的紋理貼圖；最后進行鼠標與鍵盤的交互，實現鼠標可以控制攝像機的高度以及鍵盤的上下左右實現攝像機的移動。

三、實驗代碼

四、實驗結果與心得

?

本次作業，對模型的坐標值的計算進行放置比較復雜，其次還有賦予材質貼圖時也出現了各式各樣的毛病，比如進行一個貼圖的賦予時，就會給整個場景賦予相同的貼圖；之后進行修改代碼，最后可以給每一個模型進行賦予材質，但也只有幾個面的貼圖鋪張是正確的顯示，目前尚未解決。通過此次大作業，對圖形學中三維可編程繪制流水線已經有部分的了解與學習。雖然過程中有各式各樣的困難但也是逐個擊破，對今后的學習也是有了較大的幫助。
