I tried this in an attempt to change a sphere_sweep done in Megapov
into a mesh. After seeing a discussion in p.a-u (I think) around 8
months ago, on how to find the tangent to a point on a spline. The
difference between (point) and (point+small_increment) will give a
vector, and you offset your triangle points from this by your required
radius and 90deg.

Hope this makes sense
