The x-coordinate of each point must be greater than zero. Default is an array with (0,-0.5), (0.5,0) and (0,0.5) which creates a simple diamond shape.<br /> segments — the number of circumference segments to generate. Default is 12.<br /> phiStart — the starting angle in radians. Default is `0`.<br /> phiLength — the radian (0 to 2PI) range of the lathed section 2PI is a closed lathe, less than 2PI is a portion. Default is 2PI. </p> <p>This creates a [name] based on the parameters.</p> <h2>Properties</h2> <p>See the base [page:BufferGeometry] class for common properties.</p> <h3>[property:Object parameters]</h3> <p> An object with a property for each of the constructor parameters.
