Description

使用GeoJSONVectorTileLayer绘制道路面,使用threeLayer.toLine绘制线段,在完全俯视的情况下,线段和道路面重合的部分会看不见。
`const geo = new GeoJSONVectorTileLayer("geo", {
data: toWgs84(data)
});

geo.setStyle({
style: [
{
renderPlugin: {
dataConfig: {
type: "fill",
},
sceneConfig: null,
type: "fill",
},
symbol: {
polygonBloom: false,
polygonFill: "#999999",
polygonOpacity: 1,
polygonPatternFile: null,
},
}
]
});

const groupLayer = new GroupGLLayer("group", [geo]);
groupLayer.addTo(map);

const mesh = threeLayer.toLine(line, { interactive: false, altitude: 3, minZoom: 10, maxZoom: 20 }, material.clone());
threeLayer.addMesh(mesh);`

Research direction

Reproduce the issue with GeoJSONVectorTileLayer, GroupGLLayer, threeLayer.toLine, and the shown altitude settings while viewing the map directly from above. Check the rendering behavior where the line overlaps the filled road surface; done means the overlapping line remains visible in the fully top-down view.
