查看lwjgl常用状态的值

在遇到状态值较多较复杂的情况，可以选择使用GL11.glIsEnabled()或者GL11.glGet()函数来查看状态机值，以下是常用值：

public static void printOpenGlArg() {
        System.out.println("GL_LIGHTING:" + GL11.glIsEnabled(GL11.GL_LIGHTING));
        System.out.println("GL_FOG:" + GL11.glIsEnabled(GL11.GL_FOG));
        System.out.println("GL_CULL_FACE:" + GL11.glIsEnabled(GL11.GL_CULL_FACE));
        System.out.println("GL_ALPHA_TEST:" + GL11.glIsEnabled(GL11.GL_ALPHA_TEST));
        System.out.println("GL_DEPTH_TEST:" + GL11.glIsEnabled(GL11.GL_DEPTH_TEST));
        System.out.println("GL_TEXTURE_2D:" + GL11.glIsEnabled(GL11.GL_TEXTURE_2D));
        System.out.println("GL_GREATER:" + GL11.glGetFloat(GL11.GL_GREATER));
        System.out.println("GL_BLEND_SRC:" + GL11.glGetInteger(GL11.GL_BLEND_SRC));
        System.out.println("GL_BLEND_DST:" + GL11.glGetInteger(GL11.GL_BLEND_DST));
        System.out.println("GL_ALPHA_TEST_FUNC:" + GL11.glGetInteger(GL11.GL_ALPHA_TEST_FUNC));
        System.out.println("GL_ALPHA_TEST_REF:" + GL11.glGetInteger(GL11.GL_ALPHA_TEST_REF));

        System.out.println("r:" + GL11.glGetFloat(GL11.GL_RED));
        System.out.println("g:" + GL11.glGetFloat(GL11.GL_GREEN));
        System.out.println("b:" + GL11.glGetFloat(GL11.GL_BLUE));
        System.out.println("a:" + GL11.glGetFloat(GL11.GL_ALPHA));
    }

    public static void printOpenGlColor() {
        System.out.println("r:" + GL11.glGetFloat(GL11.GL_RED));
        System.out.println("g:" + GL11.glGetFloat(GL11.GL_GREEN));
        System.out.println("b:" + GL11.glGetFloat(GL11.GL_BLUE));
        System.out.println("a:" + GL11.glGetFloat(GL11.GL_ALPHA));
    }
