計算機圖形學大作業(yè)

一、實驗要求

繪制一個簡單的三維場景，可以是室內(nèi)：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(nèi)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(nèi)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(shù)實現(xiàn)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(xiàn)模型材質(zhì)的紋理貼圖；最后進行鼠標與鍵盤的交互，實現(xiàn)鼠標可以控制攝像機的高度以及鍵盤的上下左右實現(xiàn)攝像機的移動。

三、實驗代碼

四、實驗結(jié)果與心得

?

本次作業(yè)，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(zhì)貼圖時也出現(xiàn)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(zhì)，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(yè)，對圖形學中三維可編程繪制流水線已經(jīng)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。
