title: Drawing 3D Geometry from 2D Objects in ThreeJS
body: <p>I am very to new to Three.js, and I been trying to implement the following:</p>
  
  <p>Suppose that I have an array of x and y coordinates for a certain shape from the browser view-port. I would like to render these shapes in Three.JS such that I can add a height in the z direction.</p>
  
  <p>The shape itself is actually a "building", where I have the array of its floorplan coordinates, and I would like to 3Dify it by adding a height in the Z-direction.</p>
  
  <p>What Geometry/Material/Technique should I use to achieve this? </p>
