mesh_refine - creates smaller triangles from a triangle mesh
[ FV ] = mesh_refine( FV, Nface )
FV.vertices - vertex matrix (Nx3)
FV.faces - face matrix (Mx3), indices into vertex matrix rows
Nface - subdivide faces into 4 or 6 faces,
the default 4 provides an even subdivision
This function calls mesh_refine_tri4 or mesh_refine_tri6. See
these for more details.0001 function [ FV ] = mesh_refine(FV,Nface) 0002 0003 % mesh_refine - creates smaller triangles from a triangle mesh 0004 % 0005 % [ FV ] = mesh_refine( FV, Nface ) 0006 % 0007 % FV.vertices - vertex matrix (Nx3) 0008 % FV.faces - face matrix (Mx3), indices into vertex matrix rows 0009 % 0010 % Nface - subdivide faces into 4 or 6 faces, 0011 % the default 4 provides an even subdivision 0012 % 0013 % This function calls mesh_refine_tri4 or mesh_refine_tri6.
