No sSPlit (in Moi3D) is used for add Lines cut for Divide a solid ( or add faces ) for facilitate the Subdivision!

_SubdivBeta9 makes the Subdivision of the solid(s) itself! (round the volume(s))

Here like 100 levels of Subdivision! ;) in Moi : in another prog that will be 0 to 7 because numbers of facetts x 4 at each level! ;)

In Hexagon 2 : 0 to 7... Level 3 is yet a cool sphere ! :) And want not explode my Hard Memory!



In Moi3D It's like a game because you must always find some tricks for have a solid(s) without internal faces !
And better to have "quad" faces!

SSplit only one edge


SSplit on faces! (special here because start is not a quad so SPlit ones Top & Bottom !


SBridge + _SubdivBeta9 at the end
S

SSize (works with Control Points) + _SubdivBeta9 at the end


Then the Free Vizcom for some cool rendering! ;)
