软件介绍

LWJGL(Lightweight Java Game Library)它可以帮助Java程序员开发有着商业性质的游戏.LWJGL为开发者提供简单易用的API来访问OpenGL (Open Graphics Library)与OpenAL (Open Audio Library) 同也提供操作控制器(Gamepads, Steering wheel和操纵杆)的API.

示例代码：

import org.lwjgl.Sys;
import org.lwjgl.opengl.*;
import org.lwjgl.system.glfw.*;
 
import java.nio.ByteBuffer;
 
import static org.lwjgl.opengl.GL11.*;
import static org.lwjgl.system.MemoryUtil.*;
import static org.lwjgl.system.glfw.GLFW.*;
 
public class HelloWorld {
 
    private long window;
 
    public void execute() {
        System.out.println("Hello LWJGL " + Sys.getVersion() + "!");
 
        try {
            init();
            loop();
            glfwDestroyWindow(window);
        } finally {
            glfwTerminate();
        }
    }
 
    private void init() {
        glfwSetErrorCallback(ErrorCallback.Util.getDefault());
 
        if ( glfwInit() != GL11.GL_TRUE )
            throw new IllegalStateException("Unable to initialize GLFW");
 
        glfwDefaultWindowHints();
        glfwWindowHint(GLFW_VISIBLE, GL_FALSE);
        glfwWindowHint(GLFW_RESIZABLE, GL_TRUE);
 
        int WIDTH = 300;
        int HEIGHT = 300;
 
        window = glfwCreateWindow(WIDTH, HEIGHT, "Hello World!", NULL, NULL);
        if ( window == NULL )
            throw new RuntimeException("Failed to create the GLFW window");
 
        WindowCallback.set(window, new WindowCallbackAdapter() {
            @Override
            public void key(long window, int key, int scancode, int action, int mods) {
                if ( key == GLFW_KEY_ESCAPE && action == GLFW_RELEASE )
                    glfwSetWindowShouldClose(window, GL_TRUE);
            }
        });
 
        ByteBuffer vidmode = glfwGetVideoMode(glfwGetPrimaryMonitor());
        glfwSetWindowPos(
            window,
            (GLFWvidmode.width(vidmode) - WIDTH) / 2,
            (GLFWvidmode.height(vidmode) - HEIGHT) / 2
        );
 
        glfwMakeContextCurrent(window);
        glfwSwapInterval(1);
 
        glfwShowWindow(window);
    }
 
    private void loop() {
        GLContext.createFromCurrent();
 
        glClearColor(1.0f, 0.0f, 0.0f, 0.0f);
        while ( glfwWindowShouldClose(window) == GL_FALSE ) {
            glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
 
            glfwSwapBuffers(window);
            glfwPollEvents();
        }
    }
 
    public static void main(String[] args) {
        new HelloWorld().execute();
    }
}
