brede_sur_refine - Refine surface
Sout = brede_sur_refine(Sin)
Input: Sin 'Sur' structure
Property: Depth [ 1 | positive integer ] Number of times to
iterate the refinement.
Output: Sout Refined 'sur' structure
Refine the surface defined in the 'sur' structure, ie, add
more polygons. The reverse operation is performed with
brede_sur_reduce.
Every triangle is converted to four triangles:
2
/\
4 /__\ 5
/\ /\
/ \/ \
1 -------- 3
6
This presently only works for triangularized surfaces.
Example:
S1 = brede_sur_tetrahedron('size', 0.05);
S2 = brede_sur_refine(S1, 'depth', 3)
figure, brede_ta3_frame, brede_ta3_sur(S2)
