+/**
+ * Draw geometric shape in wire mode (only edges)
+ *
+ * Arguments: the sphere, in wire mode, consists of multiple line
+ * loops for the stacks, and for the slices. The vertex indices for
+ * all slices are thrown together. numParts is how many separate loops
+ * are in the array, numVertIdxsPerPart is how many vertices there are
+ * per loop. For those suffixed with 2, its exactly the same
+ * principle, the number of stacks and slices is not the same.
+ *
+ * Feel free to contribute better naming ;)
