一、所需工具软件 1. Python 2. Pycharm
二、使用步骤
代码如下示例

}void display() {glColor3f(1.0, 1.0, 1.0);glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);glMatrixMode(GL_MODELVIEW);glLoadIdentity();// 应用平移和缩放glTranslatef(transX, transY, -270.0f); // 应用水平和垂直平移141.0fglScalef(zoomFactor, zoomFactor, zoomFactor); // 应用缩放setLightRes();glPushMatrix();// 更新gluLookAt以使用vertDegree进行垂直旋转float vertRad c * vertDegree; // 将vertDegree转换为弧度gluLookAt(r * cos(c * degree) * cos(vertRad), r * sin(vertRad), r * sin(c * degree) * cos(vertRad),0.0f, 0.0f, 0.0f,0.0f, 1.0f, 0.0f);// 根据计算出的中心坐标平移模型glTranslatef(-objModel.center[0], -objModel.center[1], -objModel.center[2]);objModel.Draw();glPopMatrix();glutSwapBuffers();
}void reshape(int width, int height) {glViewport(0, 0, width, height);glMatrixMode(GL_PROJECTION);glLoadIdentity();gluPerspective(60.0f, (GLdouble)width / (GLdouble)height, 1.0f, 200.0f);glMatrixMode(GL_MODELVIEW);
}// 在全局范围内定义一个变量来追踪当前鼠标操作

}//滚轮没反应

}void specialKeys(int key, int x, int y) {switch (key) {case GLUT_KEY_UP:// 按下上方向键进行相应操作break;case GLUT_KEY_DOWN:// 按下下方向键进行相应操作break;}glutPostRedisplay();
}void myIdle() {glutPostRedisplay();
