Collada攻略戦01

今日からColladadomによるdaeファイルの読み込みをやっていこうと思う。Colladadomのビルドについては今回は割愛。

参考にさせていただいたのは、hyper_jaianismさんの記事COLLADA DOM を使うです。
まずはファイルを開くための最短コード。

view sourceprint?
01#include <iostream>
02#include <dae.h>
03 
04int main()
05{
06   DAE dae;
07 
08   if(dae.load("./cube.dae") == DAE_OK)
09      std::cout << "File opened." << std::endl;
10   else
11      std::cout << "Couldn't open the file." << std::endl;
12 
13   dae.cleanup();
14   DAE::cleanup();
15 
16   return 0;
17}
実行して"File opened."と表示されればとりあえず成功だと思います。
TODO:
  • 頂点座標・法線・UV座標を読み込む
  • テクスチャ名を読み込む
読み込むファイルは立方体。Blenderがcollada形式で出力できるので使ってみるといいかもです。テキストデータですから、下記にも貼り付けておきます。メモ帳などにコピペして保存すればオッケーかと。念のためエンコードはUTF-8に変更してみてください。
