week12 溫洺漢 上課筆記

加入以下程式
#include <math.h>


glMatrixMode(GL_PROJECTION);
    glLoadIdentity();
    gluPerspective(60, 1, 0.001, 10000);
    glMatrixMode(GL_MODELVIEW);

到jsyeh.org/3dcg10下載data windows glut32.dll
解壓縮windows並把glut32.dll跟data的壓縮檔拉進解壓縮的windows裡面

加入以下程式碼
#include <GL/glut.h>
float eyeX=0, eyeY=0, eyeZ=1;
float centerX=0, centerY=0, centerZ=0;
float upX=0, upY=1, upZ=0;
static void display(void)
{
    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
    glColor3d(1,0,0);
    glPushMatrix();
    gluLookAt(eyeX, eyeY, eyeZ,
              centerX, centerY, centerZ,
              upX, upY, upZ);
              glutSolidTeapot(0.3);
     glPopMatrix();
    glutSwapBuffers();
}
