  Camera clipping bounds (Message 1 to 5 of 5)

Hi All,

Please excuse my ignorance, but I can't find a reference anywhere to the
closest distance from the camera at which an object will be visible.
What I mean is that I understand that there is a limit to how close to
the camera an object can be whilst still being visible, but I don't know
what that limit is, or whether the limit is changed when the camera is
scaled.

Thanks heaps,

Anton

There is no limit.

  There is a limit because of inaccuracies of floating point numbers... :)

  There may also be a coded epsilon limit.

IIRC, bounding error is 1/1000, or something.  As long as you're not within
that, you're ok.

Thanks for your help everyone, I guess I'll have to look elsewhere for
my bug then
