glClearColor被忽略

问题描述

我正在尝试将背景色设置为蓝色，但是glClearColor被完全忽略了。
代码：

glfwWindowHint(GLFW_RESIZABLE,GL_FALSE);
GLFWwindow* window = glfwCreateWindow(640,480,"3D Shooter",NULL,NULL);
glClearColor(0.5f,0.5f,1.0f,1.0f);
while (!glfwWindowShouldClose(window)) {
    glClear(GL_COLOR_BUFFER_BIT);
    glfwSwapBuffers(window);
    glfwPollEvents();
}

解决方法

您似乎想念一个

glfwMakeContextCurrent(window);
