Dear rooters, I made T->Draw("fTracks.fPx:fTracks.fPy","1","surf") and tried to apply "View with X3D" to the picture but got: gSize3D.numPoints=0 gSize3D.numSegs =0 gSize3D.numPolys =0 Error in <TCanvas::x3d>: x3d buffer allocation failure Is it possible to view histograms/surfaces with X3D or not? By the way, I observed the strange thing in http://root.cern.ch/root/Search : if I look for "x3d" I got: Search expression: "x3d" in Complete Web Site No matches found! Instead if I look for "x3d*" - the matches are a lot. It looks as the low limit on the number of letters (2) in the string and the digit is not considered as a letter in this case. Why not? Regards, Valeri
