BabylonJS-IcoSphere

これは、MeshBuilderで使用される形状の1つです。

構文

var icosphere = BABYLON.MeshBuilder.CreateIcoSphere("ico", {radius: 5, radiusY: 3, subdivisions: 2}, scene);

パラメーター

IcoSphereを作成するには、次のパラメータを考慮してください-

半径-球の半径。
RadiusY -y軸に沿った半径。
サブディビジョン-リングの数。
シーン-球体をアタッチする必要があるシーン。

次のデモ例には、Ground、Cone、Plane、Disc、Torus、Polyhedron、およびIcoSphereの形状が含まれています。
