yes, they are numbered from 0 to 120, 121 is one past the end of the
array (actually a std::vector<>).

createOptimizedPrimitives() - it generates triangle strips and fans
which render faster, because a triangle in a strip/fan reuses two
vertices from the previous triangle so they don't have to be transformed
twice by the hardware.
