Hello Xavier,
Your statements like:
par0[i] = gr1_0->GetBinContent(i);
should work. Can you draw the gr1_xx histograms ?
Could you send me a macro + the histogram file ?
About X3D. The following options are supported
W Wireframe mode (default)
E Hidden Line removal mode
R plain surface mode
S Stereo mode (works only on 8 bits color planes)
type M for a list of all possible options
