It seems to be related to the *eps*
value which makes compute-split-types
classify the polygon wrongly. ie: t
is larger then *eps*
or t
smaller then (- *eps*)
hence the polygon gets split-type 1 or 2, instead of the expected split-type 0 (as a csg-node
with a single polygon of course should).
Not sure how to handle this. Guess there's some 'best' *eps*
.
For now I'll fiddle with (set! thi.ng.math.core/*eps* MY_EPSILON)
Setting *eps*
to 0.001
fixes the issue above, but well, guess it'll introduce others :)
NOTE: the t
of the problem polygon in previous post is 0.000003032253516721539
with the default *eps*
of 0.000001
. Hence.
from geom.
(binding [thi.ng.math.core/*eps* MY_EPS]
; csg stuff here
)
Seems to do the job fine...
