[Plib-users] vertex optimization ?

[<Rol...@t-...>]

Hello,

Is there an optimization to kill nearby vertexes ?
I have quite small characters (~0.61 in height) and after some changes to the 
model one hand shows up as only two lines when loaded into plib. In the 
modeller (AC3D) it's ok. Also a two sided mesh partly disappears depending on 
the camera angle.

Is there an absolute threshold I should consider when drawing small things ?
Currently the smallest distance between vertexes is about 0.005.

Thanks,
Rolf

Yes - I think someone must have added something like that.

I just created a very tiny cube in AC3D - and when I load it into PPE (a PLIB-based
modeller), it comes out as a flat rectangle.

Evidently.

Does anyone want to confess to making this change? If so, the threshold needs
to be **MUCH** smaller.

Could someone point me to where to lower this threshold ?
The alternative to scale everything up scares me as I have several absolute 
positions in a database which would be invalid after scaling the scene.

Maybe my problem with ssgLOS is also related to that ?

Thanks,
Rolf
