glfwSetWindowSizeCallback:用于设置窗口大小变化事件的回调函数,并在用户调整窗口大小时触发。 glfwSetWindowCloseCallback:用于设置窗口关闭事件的回调函数,并在用户尝试关闭窗口时触发。 这些回调函数提供了对与用户输入和窗口事件相关的操作的通知机制。可以通过设置适当的回调函数来处理这些事件,以便在用户与窗口进行交互...

通过glfw的回调函数都可以实现,设置bool变量做标志位,分别在mouse_button_callback中通过是按住对应按键修改标志位,然后在mouse_callback(GLFWwindow* window, double xpos, double ypos)中根据标志位判断是否根据鼠标偏移量(上一帧和当前帧的位置差)调整摄像机,这里最好用deltatime固定一下摄像机速度。 平移(只改变...
On some platforms, a window move, resize or menu operation will cause event processing to block. This is due to how event processing is designed on those platforms. You can use thewindow refresh callbackto redraw the contents of your window when necessary during such operations. ...
2.int glfwGetKey(GLFWwindow* window, int key):返回指定窗口window中指定按键key的状态,可以是GLFW_PRESS(按下键),GLFW_RELEASE(松开键),GLFW_REPEAT(连续输入模式)中的一个。 3.GLFWcursorposfun glfwSetCursorPosCallback(GLFWwindow* window, GLFWcursorposfun cbfun):设置一个新的鼠标光标位置回调函数cbfun...
GLFWAPI void glfwSetWindowIcon(GLFWwindow* window, int count, const GLFWimage* images); 为窗口设置Icon,传入一组备选图像,会选择尺寸接近的作为图标,如果没有传图像,用默认的图标。图像是32bit小端non-premultiplied RGBA8,按行排列从左上角开始。图像的尺寸会根据平台和系统设置进行resize,一般包括16x16,32x32...
