- 2.游戏相机与轨迹球相机切换
- 3.博主笔记本要运行需要更改的文件
- - 更改1:28_OpenGL_CameraSystem/application/Application.cpp
  - 更改2:28_OpenGL_CameraSystem/application/CMakeLists.txt
  - 更改3:28_OpenGL_CameraSystem/assets/shaders/fragment.glsl

1.运行

1.1.游戏相机

鼠标右键按住可控制旋转
在这里插入图片描述

1.2.轨迹球相机

在这里插入图片描述

2.游戏相机与轨迹球相机切换

注意代码文件中是拼写错误的GameCameraControl.h，应该是小写g

#include "application/camera/trackBallCameraControl.h"
#include "application/camera/gameCameraControl.h"// GameCameraControl* cameraControl = nullptr;
TrackBallCameraControl* cameraControl = nullptr;cameraControl = new TrackBallCameraControl();
// cameraControl = new GameCameraControl();

3.博主笔记本要运行需要更改的文件

Files 28_OpenGL_CameraSystem/application/Application.cpp and diff_temp/28_OpenGL_CameraSystem/application/Application.cpp differ
Files 28_OpenGL_CameraSystem/application/CMakeLists.txt and diff_temp/28_OpenGL_CameraSystem/application/CMakeLists.txt differ
Files 28_OpenGL_CameraSystem/assets/shaders/fragment.glsl and diff_temp/28_OpenGL_CameraSystem/assets/shaders/fragment.glsl differ
Files 28_OpenGL_CameraSystem/assets/shaders/vertex.glsl and diff_temp/28_OpenGL_CameraSystem/assets/shaders/vertex.glsl differ
Files 28_OpenGL_CameraSystem/CMakeLists.txt and diff_temp/28_OpenGL_CameraSystem/CMakeLists.txt differ

更改1:28_OpenGL_CameraSystem/application/Application.cpp

在这里插入图片描述

更改2:28_OpenGL_CameraSystem/application/CMakeLists.txt

在这里插入图片描述

#递归将本文件夹下所有cpp
file(GLOB_RECURSE APP ./  *.cpp)add_library(app ${APP} )target_include_directories(app PRIVATE ${CMAKE_CURRENT_BINARY_DIR})
target_link_libraries(app PRIVATE glfw)

更改3:28_OpenGL_CameraSystem/assets/shaders/fragment.glsl

在这里插入图片描述

更改4:28_OpenGL_CameraSystem/assets/shaders/vertex.glsl

在这里插入图片描述

更改5:28_OpenGL_CameraSystem/CMakeLists.txt

在这里插入图片描述
