New question #240509 on Yade: https://answers.launchpad.net/yade/+question/240509
Dear Yade-Dev, I have problems with rendering of faces of my deformable tetrahedron class that I defined within yade. Within deformable tetrahedrons, each vertex is defined in a list and each face of the deformable tetrahedron also defined in another list including it's connected vertex indices. I create tetrahedrons by importing mesh from a gmsh file where its node numbering order is given in gmsh's manual. When I try to give opengl the normal of each face with the calculating method given here[1] or even calculating it with the node numbering as given in the user manual of gmsh , I see the coloring difference of the tetrahedrons faces. My drawing function of the deformable elements can be found here[2]. So I want to ask; What may cause the difference of the colors of the faces of tetrahedron with the code given at[2]? Do you suggest a better way to draw a tetrahedron?
