This pair of images contrasts a traditionally rendered transparent surface with a rendering in which the transparent surface has been enhanced by a carefully constructed pattern of thin opaque lines. The intention of the lines is to both more explicitly define the 3D location of the outer surface (via more reliable occlusion and vergence cues), and to more clearly indicate its 3D shape. The texturing technique illustrated in the image on the right is described in my 1997 SIGGRAPH paper "Illustrating Surface Shape in Volume Data via Principal Direction-Driven 3D Line Integral Convolution" (2.4M pdf) (HTML).
