一、所需工具软件

       1. Python
       2. Pycharm

二、使用步骤

代码如下（示例）：

void init() {glutInitDisplayMode(GLUT_DOUBLE | GLUT_RGB | GLUT_DEPTH);glutInitWindowSize(500, 500);glutCreateWindow("ObjLoader");glEnable(GL_DEPTH_TEST);//glDisable(GL_DEPTH_TEST);glShadeModel(GL_SMOOTH); setLightRes();glEnable(GL_DEPTH_TEST);// objModel.Init();glDepthFunc(GL_LEQUAL); // 设置深度测试函数
}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
enum MouseAction { NONE, ROTATE, TRANSLATE };
MouseAction currentAction = NONE;void mouseButton(int button, int state, int x, int y) {if (state == GLUT_DOWN) {if (button == GLUT_LEFT_BUTTON) {currentAction = ROTATE;oldPosX = x;oldPosY = y;}else if (button == GLUT_RIGHT_BUTTON) {currentAction = TRANSLATE;oldRightPosX = x;oldRightPosY = y;}}else if (state == GLUT_UP) {currentAction = NONE;}
}void mouseMove(int x, int y) {if (currentAction == ROTATE) {int deltaX = x - oldPosX;int deltaY = y - oldPosY;degree += deltaX;vertDegree += deltaY;oldPosX = x;oldPosY = y;}else if (currentAction == TRANSLATE) {transX += (x - oldRightPosX) * 0.01f;transY -= (y - oldRightPosY) * 0.01f;oldRightPosX = x;oldRightPosY = y;}glutPostRedisplay();
}//滚轮没反应
void mouseWheel(int wheel, int direction, int x, int y) //
{cout << "test " << endl;cout << "Mouse wheel event detected. Direction: " << direction << endl;if (direction > 0) {zoomFactor += 0.1f; // 增加缩放因子}else {zoomFactor -= 0.1f; // 减小缩放因子}// 防止缩放因子小于等于0if (zoomFactor <= 0.1f) {zoomFactor = 0.1f;}glutPostRedisplay();
}void processNormalKeys(unsigned char key, int x, int y) {switch (key) {case 'w': // Pressing "w" key, zoom incout << "Zoom factor increased by 0.1\n"; zoomFactor += 0.1f;break;case 's': // Pressing "s" key, zoom outzoomFactor -= 0.1f;if (zoomFactor <= 0.1f) {zoomFactor = 0.1f; // Prevent zoomFactor from going below 0.1}break;case 27: // Pressing the Esc key (ASCII value 27) to exit the programexit(0);break;// Add more cases for handling other keys as needed}glutPostRedisplay();
}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();
}int main(int argc, char* argv[]) {glutInit(&argc, argv);init();glutDisplayFunc(display);glutReshapeFunc(reshape);glutMouseFunc(mouseButton);glutMotionFunc(mouseMove);glutMouseWheelFunc(mouseWheel);glutKeyboardFunc(processNormalKeys);     // 处理一般的键盘事件glutSpecialFunc(specialKeys);  // 处理特殊键盘事件glutIdleFunc(myIdle);// 在此处调用 CalculateCenter() 函数objModel.CalculateCenter();// 打印模型的中心坐标objModel.PrintCenter();// 计算并打印模型长宽高objModel.CalculateBoundingBox();objModel.PrintBoundingBox();glutMainLoop();return 0;
}
