Hi, The trouble thing is that in my case, the performances are the same if I either use a SharedGroup, I share the Geometry or that I repeat the "geometry" with no sharing at all. I can garantee you that In that case, OpenGL Display lists are efficients. The worst is that on pure performance, OpenGL and J3D arevquite similar (I mean displaying over a thousand of random lines). It is jsut in the case of a repetition of geometry that J3D perf falls down versus OpenGL.
Thanks for your comments!!!

Just a comment: Well In my experience display lists in OpenGL are not always good performance wise (at least on NVIDIA Cards) it really depends on how many display lists and how big the display lists are. Sometimes it's better not to use display lists at all.
