  • Creates a sphere based upon an icosahedron with 20 triangular faces which can be subdivided

    • The parameter radius sets the radius size (float) of the icosphere (default 1)
    • You can set some different icosphere dimensions, for instance to build an ellipsoid, by using the parameters radiusX, radiusY and radiusZ (all by default have the same value of radius)
    • The parameter subdivisions sets the number of subdivisions (postive integer, default 4). The more subdivisions, the more faces on the icosphere whatever its size
    • The parameter flat (boolean, default true) gives each side its own normals. Set it to false to get a smooth continuous light reflection on the surface
    • You can also set the mesh side orientation with the values : BABYLON.Mesh.FRONTSIDE (default), BABYLON.Mesh.BACKSIDE or BABYLON.Mesh.DOUBLESIDE
    • If you create a double-sided mesh, you can choose what parts of the texture image to crop and stick respectively on the front and the back sides with the parameters frontUVs and backUVs (Vector4). Detail here : https://doc.babylonjs.com/babylon101/discover_basic_elements#side-orientation
    • The mesh can be set to updatable with the boolean parameter updatable (default false) if its internal geometry is supposed to change once created
