自製3D模型、利用mouse旋轉

Vertex3f 畫出3D圖

#include<GL/glut.h>

float angle=0;

void display()

{

    glClear(GL_COLOR_BUFFER_BIT);

    glPushMatrix();

        glRotatef(angle,1,0,0);

        glBegin(GL_LINE_LOOP);

            glVertex3f(0.3,0.2,-0.8);

            glVertex3f(0.2,-0.3,-0.8);

            glVertex3f(-0.2,-0.3,-0.8);

            glVertex3f(-0.3,0.2,-0.8);

        glEnd();

        glBegin(GL_POLYGON);

            glVertex3f(0.2,0.3,0.8);

            glVertex3f(0.3,-0.2,0.8);

            glVertex3f(-0.3,-0.2,0.8);

            glVertex3f(-0.2,0.3,0.8);

        glEnd();

    glPopMatrix();

    glFlush();

    angle+=0.01;

}

int main (int argc,char **argv)

{

    glutInit(&argc,argv);

    glutCreateWindow("02160430³¯ÁcøÊ");

    glutDisplayFunc(display);

    glutIdleFunc(display);

    glutMainLoop();

}

簡潔的CB畫面

分別畫出面和線~凸顯3D效果

利用滑鼠旋轉

開啟深度模式

glutInitDisplayMode(GLUT_DEPTH);

在CreateWindow指令之前, glutInit之後
