Getting Started - Chapter 2 - Basic House

A Basic House

Adding a roof would make our box more house like. We need a prism like shape. Luckily we can do that using CreateCylinder. Well the name might imply a cylinder rather than a prism however in using it you need to state how may points around the circumference of the cylinder and for a prism we can use three points.

const roof = BABYLON.MeshBuilder.CreateCylinder("roof", {diameter: 1.3, height: 1.2, tessellation: 3});
roof.scaling.x = 0.75;
roof.rotation.z = Math.PI / 2;
roof.position.y = 1.22;

Since the cylinder is created vertically we needed to rotate it to a horizontal position and scale it down in one direction so that the height of the roof is less than its width.
