I'm stumped on this one:
I have a *very* simple model (a single triangle face) where I'm trying to move a vertex to a very specific position, but it doesn't want to do it!!
Ok, so if I start a new scene, here is my model:
polyCreateFacet -ch on -tx 1 -s 1 -p 0 0 10 -p 0 10 0 -p 1 1 1;
I want to move vertex1 from to this exact position (0, 20.005, 0 ), so I move it:
xform -ws -t 0 20.005 0 polySurface1.vtx[1];
But yet when I check the position, it hasn't moved to the exact spot!! Not the 20.005 I wanted, but instead 20.004999 ??
xform -q -ws -t polySurface1.vtx[1];
// Result: 0 20.004999 0 //
Sure, I can move it to other positions and it works, but why not 20.005 ??
Is this some float issue? It doesn't seem like it's a particularly complex number or anything?
Any explanations would be appreciated; I'm baffled!!! :eek:
