21:16:30selwyneven for 'precision' physics you don't need to take floating point into account unless your scales are wildly different (which they shouldn't be)
21:16:52shinmeraI'm still talking about single float
22:25:25selwynis there an example in which floating point errors mess things up
22:27:03shinmerathere's small deviations from the reference implementation that are due to floating point precision errors accumulated from the differences in implementation of the matrix stack.
23:10:43ColleenI'm surprised that switching float width is a non-trivial change. Are you relying on the bit-representation of the floats or something?

7:00:13shinmeraSAL9000: the entire library stack is done with single floats, all the constants are single floats. switching the stack would mess with everything else.
