+/**
+ * @author Eric Haines / http://erichaines.com/
+ *
+ * Tessellates the famous Utah teapot database by Martin Newell into triangles.
+ *
+ * THREE.TeapotGeometry = function ( size, segments, bottom, lid, body, fitLid, blinn )
+ *
+ * defaults: size = 50, segments = 10, bottom = true, lid = true, body = true,
+ * fitLid = false, blinn = true
+ *
+ * size is a relative scale: I've scaled the teapot to fit vertically between -1 and 1.
+ * Think of it as a "radius".
+ * segments - number of line segments to subdivide each patch edge;
+ * 1 is possible but gives degenerates, so two is the real minimum.
+ * bottom - boolean, if true (default) then the bottom patches are added. Some consider
+ * adding the bottom heresy, so set this to "false" to adhere to the One True Way.
+ * lid - to remove the lid and look inside, set to true.
+ * body - to remove the body and leave the lid, set this and "bottom" to false.
+ * fitLid - the lid is a tad small in the original. This stretches it a bit so you can't
+ * see the teapot's insides through the gap.
+ * blinn - Jim Blinn scaled the original data vertically by dividing by about 1.3 to look
+ * nicer. If you want to see the original teapot, similar to the real-world model, set
+ * this to false. True by default.
+ * See http://en.wikipedia.org/wiki/File:Original_Utah_Teapot.jpg for the original
+ * real-world teapot (from http://en.wikipedia.org/wiki/Utah_teapot).
+ *
+ * Note that the bottom (the last four patches) is not flat - blame Frank Crow, not me.
+ *
+ * The teapot should normally be rendered as a double sided object, since for some
+ * patches both sides can be seen, e.g., the gap around the lid and inside the spout.
+ *
+ * Segments 'n' determines the number of triangles output.
+ * Total triangles = 32*2*n*n - 8*n [degenerates at the top and bottom cusps are deleted]
+ *
+ * size_factor # triangles
+ * 1 56
+ * 2 240
+ * 3 552
+ * 4 992
+ *
+ * 10 6320
+ * 20 25440
+ * 30 57360
+ *
+ * Code converted from my ancient SPD software, http://tog.acm.org/resources/SPD/
+ * Created for the Udacity course "Interactive Rendering", http://bit.ly/ericity
+ * Lesson: https://www.udacity.com/course/viewer#!/c-cs291/l-68866048/m-106482448
+ * YouTube video on teapot history: https://www.youtube.com/watch?v=DxMfblPzFNc
