Hi Stefano, I cannot reproduce this problem. TViewerX3D is included in libX3d.so Can you execute the shapes.C demo ? In case of the example surfaces.C, you should see the following messages in stdout: root [2] Total size of x3d primitives: gSize3D.numPoints= 0 gSize3D.numSegs = 0 gSize3D.numPolys = 0 a lego/surf plot cannot be visualized (yet) with x3d/OpenGL.
