Hi experts, 

Is it feasible to generate background mesh to non-planar surface, such as the surface of a  sphere?

For planar surface, it is easy to generate a background mesh, which consists of scalar triangles. But for non-planar surface, the inner points of triangles are not on the surface even when the vertices of scalar triangles lie on the surface. 

Could anyone suggest a workaround if there's no direct solution? Thanks
