week 04

 
                                              到www.cmlab.csie.ntu.edu.tw/~jsyeh/3dcg10
                                                                   下載windows.zip
                                                                           data.zip
                                                                          glut32.dll

 

windows.zip解壓縮，將data放進windows裡，並且glut32.dll也放進windows裡，這樣就能開啟保時捷進行移動，旋轉，縮放

 

 

到freeglut windows下載紅線所圈的

 

在freeglut的lib裡面複製一個libglut32.a

 

先把week03所學的用滑鼠移動茶壺程式寫出來

 

移動茶壺程式碼:

 

#include <GL/glut.h>
float x=0, y=0;
void display()
{
    glClear( GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT );
    glPushMatrix();
        glTranslatef( (x-150)/150.0, -(y-150)/150.0, 0);
        glutSolidTeapot(0.3);
    glPopMatrix();
    glutSwapBuffers();
}
void motion(int nowx, int nowy)
{
    x=nowx; y=nowy;
    display();
}
int main(int argc, char**argv)
{
    glutInit(&argc, argv);
    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);
    glutCreateWindow("week04_translate");
    glutDisplayFunc(display);
    glutMotionFunc(motion);
    glutMainLoop();
}

 

多加了這行程式碼glRotatef(x,0,1,0); 可讓茶壺旋轉
