推荐答案

获得你想要的形状的最简单方法可能是挤出 THREE.Shape ，如下所示：

Probably the easiest way to get the shape you want is to extrude a THREE.Shape like so:

var settings = {
    amount: 2,
    steps : 1,
    bevelEnabled: false,
    curveSegments: 24
};

var shape = new THREE.Shape();
shape.moveTo( 0, 0 );
shape.absarc( 0, 0, 10, 0, Math.PI * 1.75, false );
shape.moveTo( 0, 0 );

var geometry = new THREE.ExtrudeGeometry( shape, settings );
