this question has answer here: is there linq way cartesian product? 3 answers how can compute cartesian product iteratively? 4 answers i have list contains further sub lists , have objects stored in sub list. want generate possible combinations of elements. e.g. have list contains 2 list l1,l2 , have different objects stored in example l1 contains {obj1,obj2} l2 contains {obj3,obj4} then result should come in form of {obj1,obj3} {obj1,obj4} {obj2,obj3} {obj2,obj4} all lists being generated dynamically. solution should generic irrespective of count of elements in main list , sub list l1.selectmany(l1 => l2.select(l2 => tuple.create(l1, l2))).tolist();

i'm using openni libraries (kinect) , opengl. can catch depth kinect (using openni , opencv) , can convert in cloud of points . so, have 640*480 points in 3d space and, viewing purpose, generate mesh composed of triangles. i need algorithm simple capable of representing walls , obstacles of every kind. can suggest me? meshlab provides algorithms this: ball pivoting, poisson triangulation , vgc. can find implementations of them in web.
