查詢立體形狀的程式碼

有很多種立體圖形可以選擇。

#include <GL/glut.h>

void display()

{

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    glPushMatrix();

        glColor3f(0,0,1);

        glScalef(0.5,0.2,0.2);

        glutSolidCube(1);///正方塊

    glPopMatrix();

    glutSwapBuffers();

}

int main(int argc, char **argv)

{

    glutInit(&argc, argv);

    glutInitDisplayMode(GLUT_RGB | GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("week09");

    glutDisplayFunc(display);

    glutMainLoop();

}

#include <GL/glut.h>
void myCube()
{
    glPushMatrix();
        glScalef(0.5,0.2,0.2);
        glutSolidCube(1);
    glPopMatrix();

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
    glPushMatrix();///再保護一次
        glColor3f(0,0.3,1);
        myCube();///用自己的函式簡化程式碼
        glTranslatef(0.4,0.1,0);

        glColor3f(0.6,0.4,0.9);
        myCube();
    glPopMatrix();///再保護一次

    glutInit(&argc, argv);
    glutInitDisplayMode(GLUT_RGB | GLUT_DOUBLE | GLUT_DEPTH);
    glutCreateWindow("week09");
    glutDisplayFunc(display);
    glutMainLoop();

}

#include <GL/glut.h>
void myCube()
{
    glPushMatrix();
        glColor3f(0.6,0.4,0.9);
        glScalef(0.5,0.2,0.2);
        glutSolidCube(1);
    glPopMatrix();
}
float angle=0;///轉動的角度變數
void display()
{
    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    glPushMatrix();
        glRotatef(angle,0,0,1);
        myCube();
    glPopMatrix();

    angle++;///每次角度增加

    glutSwapBuffers();
}
int main(int argc, char **argv)

{
    glutInit(&argc, argv);
    glutInitDisplayMode(GLUT_RGB | GLUT_DOUBLE | GLUT_DEPTH);
    glutCreateWindow("week09");
    glutIdleFunc(display);///有空idle時，再重畫畫面
    glutDisplayFunc(display);
    glutMainLoop();

}


(會轉動) 畫面中心點轉動

#include <GL/glut.h>
void myCube()
{
    glPushMatrix();
        glColor3f(0.6,0.4,0.9);
        glScalef(0.5,0.2,0.2);
        glutSolidCube(1);
    glPopMatrix();
}
float angle=0;
void display()
{
    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    glPushMatrix();
        glRotatef(angle,0,0,1);
        glTranslatef(0.22,0,0);///把要轉動的中心點，放到畫面中心
        myCube();
    glPopMatrix();
    angle++;

    glutSwapBuffers();
}
int main(int argc, char **argv)

{
    glutInit(&argc, argv);
    glutInitDisplayMode(GLUT_RGB | GLUT_DOUBLE | GLUT_DEPTH);
    glutCreateWindow("week09");
    glutIdleFunc(display);///有空idle時，再重畫畫面
    glutDisplayFunc(display);
    glutMainLoop();

}

(會轉動) 移動物體位置，也是從移動物體的位置，畫面中間轉動

        glColor3f(0.6,0.4,0.9);
        glScalef(0.5,0.2,0.2);

float angle=0;
void display()
{
    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    glPushMatrix();
        glTranslatef(0.3,0.3,0);///把下面旋轉中的方塊，掛到右上角
        glRotatef(angle,0,0,1);
        glTranslatef(0.22,0,0);
        myCube();
    glPopMatrix();
    angle++;

    glutSwapBuffers();

    glutInitDisplayMode(GLUT_RGB | GLUT_DOUBLE | GLUT_DEPTH);
    glutCreateWindow("week09");
    glutIdleFunc(display);
    glutDisplayFunc(display);
    glutMainLoop();

}


(會轉動)移動物體的位置，繞一整個圈
