Java 点动平滑度

我正在使用JOGL-OpenGL。我有带彩色边的色带，我使用三角形基本体创建，如线框图像所示。边本身由三角形组成。如何获得平滑的边缘？我查了反走样，我不确定这是否是我需要采取的方法

我愿意改变设计，我需要边界线和重叠的图案格式。我试过下面的混合，问题是三角形太近了，没有任何区别

 gl.glDisable(GL2.GL_LINE_SMOOTH);
 gl.glDisable(GL2.GL_POLYGON_SMOOTH);
 gl.glEnable(GL2.GL_MULTISAMPLE);

有人能给我指一下正确的方向吗。这是代码

@Override
public void display(GLAutoDrawable drawable) {
    GL2 gl = drawable.getGL().getGL2();

    int ind = 0;
    int nind = 0; // normal index

也许你应该在你的系统中启用多重采样 例如：

GLCapabilities STANDARD_CAPS;
STANDARD_CAPS = new GLCapabilities(GLProfile.get(GLProfile.GL2)); //I assume taht you are using GL2
STANDARD_CAPS.setBackgroundOpaque(true); //opaque background
STANDARD_CAPS.setHardwareAccelerated(true); //hardware acceleration
STANDARD_CAPS.setSampleBuffers(true); //Enable sampling
STANDARD_CAPS.setNumSamples(8); //8 Samples

创建上下文时需要指定mutlisampling；我不认为做glEnableGL_多样本是不够的，你能给我举个例子吗？在JOGL中实现的东西。我已经用尽了我的谷歌能力。你的性能有限吗？不，我想做的事情并不太复杂。只是一个简单的模拟。我添加了多重采样，它似乎使它稍微好一点。请参阅所附图片。我还能做些什么来获得更好的结果吗？你可以用样品做实验。希望能有帮助。
