Hello all,
a quick update on my progress so far:

Cliff was able to provide a patch that should increase the robustness of
the build for future *nix distros who may choose to forgo 32-bit support.

I've just about finished working on the analysis functions for basic
primitives with explicit formulae for their surface areas and volumes,
the ones remaining are more exotic like ars, arbn or bot, or cannot be
computed exactly because they involve ellipses or hyperbola. There are a
number of g
i've made good progress on my project so far. volume, surface area and
centroid functions have been written for:
ell
tor
tgc (rcc, rec, tec, and volume but no surface area for trc)
rpc

and these new functions have been added to the rt_functab interface and
implemented in MGED's analyze
primitive is defined in that way. If you
raytrace it, you will find it slightly different from what you see
from the draw command.

hello, I have another Bezier question.
I'm splitting a bezier curve with ON_BezierCurve::Split, and I get two
pieces. Lets call them first and rest. Then I need to split "first"
again into first1, first2. Is it possible to join first2 and rest into
one bezier curve? there shouldnt be any probl
i suppose i could just get all the control points of first2 and rest
with GetCV, and then create a new Bezier which uses all the control
points. Would that be the best way to do it?

Hello, another question about working with the openNURBS library.
I'm trying to create an ON_BezierCurve from a C array of 2d points
(defined as pointers to fastf_t's). I thought i could easily turn the C
array into an ON_2dPointArray and then call the ON_BezierCurve
constructor on the ON_2dPoi
thanks Wu, Append() was the method I was looking for. If I had looked
through the ON_SimpleArray base class i would have found it.

Maybe you can first construct an empty ON_2dPoi
be more than tolerance at some point but
wouldn't necessarily ever be EQUAL at any point, unless I'm
misunderstanding.

Hello all,
The original goal of my project was to add volume/centroid functions to
a few primitives (most, but not all) as well as refactor the analyze_*
functions used by MGED's analyze command to use the newly added functions.

Oliver,
One method i've seen used in the librt library is to count the number of
times a ray originating at the point in question intersects with the
surface of the object. If the number of times is even, the point is
outside the object. If odd, the point is inside. What specific BRL-CAD
