For me it's the dist_exp which is more obscure: it's explained for 0, 
but what are other value ? (btw, a "box" (2D) <0,0> to <1,1> extended to 
infinity along orientation... isn't that a square and a normal to 
select... what ? On second reading, the box is infinite along 
orientation and a square in perpendicular directions.

And what is that "distance" in the text ?

Yet another case of: better open the source to understand.


At least, I understand "planar", but there is no picture for it !
And "cubic", nice cubic !

it would rather be u_orientation, or u_something, as v is already set by 
the shape and its symetry. u_zero ?

"second_base_vector_of_half_plane_with_symetry_axis_where_u_is_zero" is 
far too long.

I would like to avoid more than one "_" if possible (so u_zero_direction 
is one word too long). Two words is nice (look_at, point_at), but three 
or more words become painful (yet, I added rational_bezier_patch 
elsewhere, so it's not so wrong, just if it could be avoided).

Oh, and for sphere_sweep, it would be the direction of u=0 for v=0, yet 
later along the sweep it would turn for continuity.

Native speakers, you're welcome !
