Dear OpenSG users,
was just curious about the coordinate mapping of the MFPositions of
the PolygonForeground (same in the PolygonBackgrond)
When giving a negative value to a position it gets corrected this way:
val = max + val; where max is the viewport pixelWidth or Height...
Does this make sense? Shouldn't the map coordinate function simply
look like this:
Real32 PolygonForeground::mapCoordinate(Real32 val, Real32 max, bool norm)
{
if (norm)
val *= max;
return val;
}
Is there a special reason for having it this way? I'm sure I'm missing
something...
Thank you,
Josef
