電腦圖學筆記-week12

1. 用3D Exploration將obj檔轉成cpp檔

save as ...

2.

新增紅框中的兩行

紅框注解掉

//        (LPLOGPALETTE) lpPalette = (LPLOGPALETTE)HeapAlloc (hHeap, 0,

 //           sizeof (LOGPALETTE) + (nColors * sizeof (PALETTEENTRY)));

結果

3.改旋轉方式(紅改藍)

    glRotatef (nAngle, 0.0f, 1.0f, 0.0f);

    glScalef (3,3,3);

#include <GL/glut.h>

void display(){

    glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);

    glPushMatrix();

        glRotatef(180,0,1,0);

        glutSolidTeapot(0.5);

    glPopMatrix();

    glutSwapBuffers();

}

const GLfloat light_ambient[]  = { 0.0f, 0.0f, 0.0f, 1.0f };

    glutInitDisplayMode(GLUT_RGB | GLUT_DEPTH | GLUT_DOUBLE);

    glutInit(&argc, argv);

    glutCreateWindow("week12");

    glLightfv(GL_LIGHT0, GL_POSITION, light_position);

    glutDisplayFunc(display);

    glutMainLoop();
