splitFV - split a mesh 1.0

%SPLITFV Splits faces and vertices into connected pieces% FVOUT = SPLITFV(F,V) separates disconnected pieces inside a patch defined by faces (F) and% vertices (V). FVOUT is a structure array with fields "faces" and "vertices". Each element of% this array indicates a separately connected patch.%% FVOUT = SPLITFV(FV) takes in FV as a structure with fields "faces" and "vertices"%% For example:% fullpatch.vertices = [2 4; 2 8; 8 4; 8 0; 0 4; 2 6; 2 2; 4 2; 4 0; 5 2; 5 0];% fullpatch.faces = [1 2 3; 1 3 4; 5 6 1; 7 8 9; 11 10 4];% figure, subplot(2,1,1), patch(fullpatch,'facecolor','r'), title('Unsplit mesh');% splitpatch = splitFV(fullpatch);% colours = lines(length(splitpatch));% subplot(2,1,2), hold on, title('Split mesh');% for i=1:length(splitpatch)% patch(splitpatch(i),'facecolor',colours(i,:));% end%% Note: faces and vertices should be defined such that faces sharing a coincident vertex reference% the same vertex number, rather than having a separate vertice defined for each face (yet at the% same vertex location). In other words, running the following command: size(unique(v,'rows') ==% size(v) should return TRUE. An explicit test for this has not been included in this function so% as to allow for the deliberate splitting of a mesh at a given location by simply duplicating% those vertices.%% See also PATCH
