使用lwjgl启用消除锯齿功能

Question

我正在运行这个lwjgl应用程序:

Display.setDisplayMode(new DisplayMode(500, 500));
Display.create();

glMatrixMode(GL_PROJECTION);
glLoadIdentity();
glOrtho(-5, 5, -5, 5, -10, 5);
glMatrixMode(GL_MODELVIEW);

float x = 0;
while (!Display.isCloseRequested()) {
    Display.update();

    glClear(GL_DEPTH_BUFFER_BIT | GL_COLOR_BUFFER_BIT);
    glEnable(GL_DEPTH_TEST);
    glColor3f(1, 0, 0);
    x += 0.01f;
    glRotatef(x, x, 3 * x, 0.5f * x);
    glBegin(GL_QUADS);
    drawCube();
    glEnd();
    glLoadIdentity();
}
Display.destroy();

这基本上是在窗口中绘制1x1x1立方体.方法drawCube()是这样的:

public void drawCube() {
    glColor3f(0.0f, 1.0f, 0.0f);          // Set The Color To Green
    glVertex3f(1.0f, 1.0f, 0f);           // Top Right Of The Quad (Top)
    glVertex3f(0f, 1.0f, 0f);             // Top Left Of The Quad (Top)
    glVertex3f(0f, 1.0f, 1.0f);           // Bottom Left Of The Quad (Top)
    glVertex3f(1.0f, 1.0f, 1.0f);         // Bottom Right Of The Quad (Top)

    glColor3f(1.0f, 0.5f, 0.0f);          // Set The Color To Orange
    glVertex3f(1.0f, 0f, 1.0f);           // Top Right Of The Quad (Bottom)
    glVertex3f(0f, 0f, 1.0f);             // Top Left Of The Quad (Bottom)
    glVertex3f(0f, 0f, 0f);               // Bottom Left Of The Quad (Bottom)
    glVertex3f(1.0f, 0f, 0f);             // Bottom Right Of The Quad (Bottom)

    glColor3f(1.0f, 0.0f, 0.0f);          // Set The Color To Red
    glVertex3f(1.0f, 1.0f, 1.0f);         // Top Right Of The Quad (Front)
    glVertex3f(0f, 1.0f, 1.0f);           // Top Left Of The Quad (Front)
    glVertex3f(0f, 0f, 1.0f);             // Bottom Left Of The Quad (Front)
    glVertex3f(1.0f, 0f, 1.0f);           // Bottom Right Of The Quad (Front)

    glColor3f(1.0f, 1.0f, 0.0f);          // Set The Color To Yellow
    glVertex3f(1.0f, 0f, 0f);             // Bottom Left Of The Quad (Back)
    glVertex3f(0f, 0f, 0f);               // Bottom Right Of The Quad (Back)
    glVertex3f(0f, 1.0f, 0f);             // Top Right Of The Quad (Back)
    glVertex3f(1.0f, 1.0f, 0f);           // Top Left Of The Quad (Back)

    glColor3f(0.0f, 0.0f, 1.0f);          // Set The Color To Blue
    glVertex3f(0f, 1.0f, 1.0f);           // Top Right Of The Quad (Left)
    glVertex3f(0f, 1.0f, 0f);             // Top Left Of The Quad (Left)
    glVertex3f(0f, 0f, 0f);               // Bottom Left Of The Quad (Left)
    glVertex3f(0f, 0f, 1.0f);             // Bottom Right Of The Quad (Left)

    glColor3f(1.0f, 0.0f, 1.0f);          // Set The Color To Violet
    glVertex3f(1.0f, 1.0f, 0f);           // Top Right Of The Quad (Right)
    glVertex3f(1.0f, 1.0f, 1.0f);         // Top Left Of The Quad (Right)
    glVertex3f(1.0f, 0f, 1.0f);           // Bottom Left Of The Quad (Right)
    glVertex3f(1.0f, 0f, 0f);             // Bottom Right Of The Quad (Right)
}

它输出这个:

对我来说线条非常可怕,lwjgl有抗锯齿吗？如果是,我该如何启用它？

Answer 1

对于抗锯齿,您可以使用多重采样.要启用它,请向Display.create();添加PixelFormat参数.这是一个例子:

Display.create(new PixelFormat(/*Alpha Bits*/8, /*Depth bits*/ 8, /*Stencil bits*/ 0, /*samples*/8));我不确定前3个参数是做什么的 - 这些是我在这里找到的值.我也看到人们使用Display.create(新的PixelFormat(8,0,0,8)).

注意:如果您将AA设置得太高(或其他值不正确的值),它将抛出LWJGLException.

希望这可以帮助.
