flat primitives scaling - Philippe Hurbain - 2015-12-11

I suggest to update text from primitive reference from
Quote:To avoid matrix arithmetic problems in some renderers, the third dimension ({y} in the default orientation) of two-dimensional primitives must be given a scaling factor of 1.
to
Quote:To avoid matrix arithmetic problems in some renderers, the third dimension ({y} in the default orientation) of two-dimensional primitives must be given a non-zero scaling factor.
There is no reason to restrict this value to 1, the only point is to avoid a non-degenerated transformation matrix.
This change should avoid sterile discussions such as this one: http://www.ldraw.org/cgi-bin/ptdetail.cgi?f=parts/u9228.dat

Seems reasonable to me. Can anybody think of a reason not to make that change? If not, I can submit it for votes. (Philo, it might be good for you to reply to this message in about a week to remind me to call for votes, if nobody else replies.)

OK. Hopefully I won't forget in between Wink

Re: flat primitives scaling - Chris Dee - 2015-12-13

I am OK with that change.

Re: flat primitives scaling - Philippe Hurbain - 2015-12-18

The week is over Wink

Call for Votes placed (with correction, since the text needs to be updated in two places).

Thanks Travis.
