我正在遵循openGL精湛圣经第七版。
在我正在查看的项目中,应该使背景色在创建的窗口中随时间变化。 https://github.com/openglsuperbible/sb7code上提供了所有项目的源文件和我使用的设置。我正在Visual Studio 2017的发行版上运行它。
下面是输出窗口的输出:

我知道这些符号在输出中不必打印出来,因为它们主要用于调试DLL中是否有错误。但是我觉得问题的根源是这一行: 'singlepoint.exe'(Win32):已加载'C:\ Windows \ System32 \ DriverStore \ FileRepository \ nvhm.inf_amd64_ebea877f10dfbbc7 \ nvinit.dll'。找不到或打开PDB文件。 我可能完全错了,但这是我目前看不到的唯一一件事。

DECLARE_MAIN(simpleclear_app)
答案 0 :(得分:1)
virtual void render(double currentTime)
{
static const GLfloat color[] = { (float)sin(currentTime*20)*2.5f+.5f,
(float)cos(currentTime*20)*2.5f+.5f,
0.0f,

}
您已将color
标记为static
。这意味着它将仅在第一次调用此函数时接收一个值,并且永远不会再次更新(并且因为它被标记为const
,所以初始化后就不能更改它,而无需依赖未定义的行为)。删除static
关键字,此功能应按您期望的方式运行。
此外,“无法找到或打开PDB文件”错误是不相关的,与您的问题无关。这样做的唯一结果是,在调试器中单步执行某些功能会更加困难。
