3D mesh orthogonal projection based texture atlas packing

摘要

The method of atlas packing receives a 3D mesh containing a plurality of triangles representing the surface of an object and determines the normal of each triangle along the positive and negative in the x-, y-, and z-directions. Classifying each triangle into one of six directions, classifying the triangles in each respective direction into layers orthogonal to each direction, identifying the components, Projecting the connected components onto a plane orthogonal to the respective direction to obtain a corresponding projected 2D connected component; cutting the projected 2D connected component into subcomponents; Packing the bounding box of all subcomponents into an atlas and each of each subcomponent Against Les triangle, and a copying the corresponding texture triangle 3D mesh each triangle.
