lwjgl을 사용하여 몇 가지 팅크 작업을하고 일부 2 차원 도형을 만듭니다. 내가 뭘 잘못하고 있는지 모르지만 화면의 첫 번째 녹색 사각형보다 더 많이 보여줄 수는 없습니다. 내 창 루프 함수 코드는 다음과 같습니다.LWJGL : OpenGL에서 둘 이상의 도형을 렌더링 할 수 없습니다.
private void loop() {
// This line is critical for LWJGL's interoperation with GLFW's
// OpenGL context, or any context that is managed externally.
// LWJGL detects the context that is current in the current thread,
// creates the GLCapabilities instance and makes the OpenGL
// bindings available for use.
GL.createCapabilities();
GLFWVidMode vidmode = glfwGetVideoMode(glfwGetPrimaryMonitor());
glOrtho(0, vidmode.width(),0, vidmode.height(),-1,1);
// Set the clear color
glClearColor(.0f, 0.6f, 0.6f, 0.0f);
// Run the rendering loop until the user has attempted to close
// the window or has pressed the ESCAPE key.
while (!glfwWindowShouldClose(window) && !dataH.isGameOver()) {
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT); // clear the framebuffer
glBegin(GL_QUADS);
