I use Performer 3.2 on windows 2000/XP.

I want that my application has the same behavior that Perfly when rendering
light point with fog. My light point is defined in a flt file.

In Perfly application, lights points appears as if they were closer than
they really are, but in my application they disappear with the fog, when I
decrease the far fog distance.

If I modify the value of the function
    pfLPStateVal((pfLPointState*)point, PFLPS_FOG_SCALE, 0.25f);
with pfLPStateVal((pfLPointState*)point, PFLPS_FOG_SCALE, 100.0f);

My light point disappear earlier.

The lpoint process callback is not called :
    - I Set the callback routines for the pfChannel
        pfChanTravFunc(channel PFTRAV_LPOINT, pointFunc);
    - My callback is
void pointFunc(pfChannel *chan, void *data)
{
    pfLPoint();
}

I think I miss a connection or I my rendering is not in the right order...

thanks for help,
M.L
