How To Create Set Shapes using Legacy Method

Box

var box = BABYLON.Mesh.CreateBox("box", 6.0, scene, false, BABYLON.Mesh.DEFAULTSIDE);

Parameters are: name, size of the box, the scene to attach the mesh, updatable? (if the mesh must be modified later) and the optional side orientation (see below). The last two parameters can be omitted if you just need the default behavior :

var box = BABYLON.Mesh.CreateBox("box", 6.0, scene);

Sphere

var sphere = BABYLON.Mesh.CreateSphere("sphere", 10.0, 10.0, scene, false,  BABYLON.Mesh.DEFAULTSIDE);

Parameters are: name, number of segments (highly detailed or not), size, scene to attach the mesh, updatable? (if the mesh must be modified later) and the optional side orientation (see below). The last two parameters can be omitted if you just need the default behavior :

var sphere = BABYLON.Mesh.CreateSphere("sphere", 10.0, 10.0, scene);

Beware to adapt the number of segments to the size of your mesh ;)

Plane

var plane = BABYLON.Mesh.CreatePlane("plane", 10.0, scene, false, BABYLON.Mesh.DEFAULTSIDE);

Parameters are: name, size, and scene to attach the mesh, updatable? (if the mesh must be modified later) and the optional side orientation (see below). The last two parameters can be omitted if you just need the default behavior :

var plane = BABYLON.Mesh.CreatePlane("plane", 10.0, scene);

Disc or Regular Polygon

var disc = BABYLON.Mesh.CreateDisc("disc", 5, 30, scene, false, BABYLON.Mesh.DEFAULTSIDE);

Parameters are: name, radius, tessellation, scene, updatable and the optional side orientation (see below). The last two parameters can be omitted if you just need the default behavior :

var disc = BABYLON.Mesh.CreateDisc("disc", 5, 30, scene);

With the tessellation value, you can get a regular polygon :
3 gives a triangle,
4 a square,
5 a pentagon,
6 a hexagon, 7 a heptagon, 8 an octogon, and so on.

Cylinder

var cylinder = BABYLON.Mesh.CreateCylinder("cylinder", 3, 3, 3, 6, 1, scene, false, BABYLON.Mesh.DEFAULTSIDE);

Parameters are: name, height, diamTop, diamBottom, tessellation, heightSubdivs, scene, updatable and the optional side orientation (see below). The last two parameters can be omitted if you just need the default behavior :

var cylinder = BABYLON.Mesh.CreateCylinder("cylinder", 3, 3, 3, 6, 1, scene);

Torus

var torus = BABYLON.Mesh.CreateTorus("torus", 5, 1, 10, scene, false, BABYLON.Mesh.DEFAULTSIDE);

Parameters are: name, diameter, thickness, tessellation (highly detailed or not), scene, updatable and the optional side orientation (see below). The last two parameters can be omitted if you just need the default behavior :

var torus = BABYLON.Mesh.CreateTorus("torus", 5, 1, 10, scene);

Knot

var knot = BABYLON.Mesh.CreateTorusKnot("knot", 2, 0.5, 128, 64, 2, 3, scene, false, BABYLON.Mesh.DEFAULTSIDE);

Parameters are: name, radius, tube, radialSegments, tubularSegments, p, q, scene, updatable and the optional side orientation (see below). The last two parameters can be omitted if you just need the default behavior :

var knot = BABYLON.Mesh.CreateTorusKnot("knot", 2, 0.5, 128, 64, 2, 3, scene);

Ground

var ground = BABYLON.Mesh.CreateGround("ground", 6, 6, 2, scene);

Parameters are: name, width, depth, subdivs, scene

Our Playground Demo Scene 01 uses a CreateGround constructor... so you can see one in action by using the link below:

Ground From HeightMap

var ground = BABYLON.Mesh.CreateGroundFromHeightMap("ground", "heightmap.jpg", 200, 200, 250, 0, 10, scene, false, successCallback);

Parameters are: name, heightmapPath, width, depth, subdivs, minheight, maxheight, scene, updatable, successCallback

HeightMap grounds are easy, but we decided to create a separate tutorial so we could say more about this important Babylon.js feature. Please see our HeightMap Tutorial to learn all about heightMap grounds.

Tiled Ground

Thanks to forum user Kostar111 for this handy Tiled Ground constructor. Here is the basic code needed to create a tiled ground.

var precision = {
    "w" : 2,
    "h" : 2
};
var subdivisions = {
    'h' : 8,
    'w' : 8
};
var tiledGround = BABYLON.Mesh.CreateTiledGround("Tiled Ground", -3, -3, 3, 3, subdivisions, precision, scene, false);

Parameters are: name, xmin, zmin, xmax, zmax, subdivisions = the number of tiles. (subdivisions.w : in width; subdivisions.h: in height), precision = the number of subdivisions inside a tile. (precision.w : in width; precision.h: in height), scene, updatable.

Kostar111 was also kind enough to give us a fine tutorial about how to use tiled grounds. Click right here to view it. At that link, Kostar111 thoroughly explains how the tiled ground works, and also provides some Babylon.js Playground scenes that nicely demonstrate some of its many uses.
