DOUBLEPATCH Splits each triangle in surface mesh into 4 congruent triangles

Examples

[v,f] = doublePatch(eye(3),1:3)
[v,f] = doublePatch(eye(3),1:3,2)
v = eye(3); f = 1:3; t = @(v,f) trimesh(f,v(:,1),v(:,2),v(:,3)); figure; t(v,f); [v,f] = doublePatch(v,f); hold on; t(v,f);
v = eye(3); f = 1:3; t = @(v,f) trimesh(f,v(:,1),v(:,2),v(:,3)); figure; t(v,f); [v,f] = doublePatch(v,f,4); hold on; t(v,f);

v = [1 3 0; 1 2 0; 2 2 0; 1 1 0; 2 1 0; 3 1 0]; f = [1 2 3; 2 4 5; 3 2 5; 3 5 6]; [v2,f2] = doublePatch(v,f); figure; patchvfc(v,f,[],'LineStyle', '--', 'FaceAlpha', 0,'LineWidth',2); hold on; patchvfc(v2,f2); axis equal tight;
[v,f] = cuboidSurface(2,3,4); [v2,f2] = doublePatch(v,f); figure; patchvfc(v,f,[],'LineStyle', '--', 'FaceAlpha', 0,'LineWidth',2); hold on; patchvfc(v2,f2); axis equal tight;
[v,f] = torusMesh; [v2,f2] = doublePatch(v,f); figure; patchvfc(v,f,[],'LineStyle', '--', 'FaceAlpha', 0,'LineWidth',2); hold on; patchvfc(v2,f2); axis equal tight;
