1-1安裝3D Exploeration 開啟模型 另存新檔(.cpp)
2-1開啟Code Blocks開OpenGL 專案
2-2.main.c換gundam_3dex.cpp(放進目錄資料夾)切換 移除main.c Add檔案
2-3Build & Run !有錯誤!
#define GL_BGR_EXT 0x80E
#define GL_BGRA_EXT 0x80E1
(加在程式一開始)
2-4註解 Palette 的2行 16105/16106
3-1 把他的旋轉 縮放註解 16251 16252 16253 16254
3-2 加上glRotatef(nAngle,0,1,0);
glScalef(3,3,3);
4-2選取要的face,export selection 要OBJexport 匯成 .obj .mtl檔
#include <GL/glut.h>
void display()
{
glClear( GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
glutSolidTeapot( 0.3 );
glutSwapBuffers();
