我有一个要绘制为实心区域的点列表。我可以将点绘制为 LineStripArray（见图）。但是当我尝试将点绘制为 IndexedTriangleArray / IndexedQuadArray 时，我得到了一个奇怪的形状。我也使用 GeometryInfo 和 Stripifier 进行了尝试，但没有成功。

通过线条连接的点

带有 GeometryInfo 的代码：

    GeometryInfo geometryInfo = new GeometryInfo(GeometryInfo.QUAD_ARRAY);
    geometryInfo.setCoordinates(points3f);

    NormalGenerator normalGenerator = new NormalGenerator();
    normalGenerator.generateNormals(geometryInfo);

    Stripifier st = new Stripifier();
    st.stripify(geometryInfo);

    Shape3D shape = new Shape3D();
    shape.setAppearance(app);
    shape.setGeometry(geometryInfo.getGeometryArray());

一个区域的解决方案（加上新问题）：

Appearance app = new Appearance();

PolygonAttributes pa = new PolygonAttributes();
pa.setCullFace(PolygonAttributes.CULL_NONE);
pa.setPolygonMode(PolygonAttributes.POLYGON_FILL);
app.setPolygonAttributes(pa);

GeometryInfo geometryInfo = new GeometryInfo(GeometryInfo.POLYGON_ARRAY);

geometryInfo.setCoordinates(points3f);
int[] stripCountArray = { points3f.length };
int[] countourCountArray = {stripCountArray.length};

geometryInfo.setContourCounts( countourCountArray );
geometryInfo.setStripCounts( stripCountArray );

NormalGenerator normalGenerator = new NormalGenerator();
normalGenerator.generateNormals(geometryInfo);

Shape3D shape = new Shape3D();
shape.setAppearance(app);
shape.setGeometry(geometryInfo.getGeometryArray());

形状也有深度。但我不能只复制数组添加 Z-index 并再次合并它们（这不起作用）。一种可能的解决方案是分别绘制每张脸，但我认为这将非常低效。

有人可以帮我解决这个问题吗？
