Thanks a bunch Curtis. That will do it. I am on Windows at the moment.

Thanks again. Ping me privately

Cheers

NIck,

I probably have a 2017 SDK around someplace for
Linux and/or Windows.  If that will do let me know and
I will look around on Monday when I get in to work...

... 
Cheers,
Curtis

Hi Curtis,

yea, same finding here. I had talk to their chat support and suddenly they
told me this issue is out of their competence. So let wait I guess

Re: [osg-users] ComputeBoundsVisitor does not consider Billboards

[Guy Volckaert]

If I have a chance, I'll try to look at it as well based on your suggestion 
solution. 

Cheers,
Guy

This is a design/implementation bug, looking that the implementation it's
clearly too simple and misses the special case of handling osg::Billboard.

To fix the bug a ComputeBoundVisitor::apply(osg::Billboard&) is required,
the implementation of this new method would need to iterator through the
_positionList and the drawables associated with each position and account
for the full rnage of potistions that are possible for each drawables
bounding box given the possible rotation and translation required.  The
easiest way to do this would be to use the diameter of each drawable
child's bounding box for the x,y and z extents.

I am not in a position to be able to write a fix right away as I have other
tasks to complete, but if you can't get to it hopefully next week I'll have
a chance to look at it.

Cheers,
Robert.

Hi Sebastian,
Thanks for the info. So far I do not encounter a lot of problems (other than, 
well, lack of documentation, as some functions do not have explanations in the 
exported doyxgen format). My application right now has just some basic features 
: loading objects, rendering using shader (I disabled the fixed pipeline in 
cmake), selecting/unselecting objects (selected objects are hihglighted with 
wireframe), transformation, undo/redo. If I am not wrong, there was something 
related to Draggers that was deprecated, so I had to searched a bit to find the 
working functions to use.

I started November last year with those two books. Then I pulled and compiled 
the "master" branch (Yeah, I should not have done that) Recently I just 
switched to the more stable version, the one with "OpenSceneGraph-3.5.6" tag.

Thanks :D

[osg-users] ComputeBoundsVisitor does not consider Billboards

[Guy Volckaert]

Hi,

I'm having problem with the osg::ComputeBoundsVisitor and osg::Billboards. In 
essence, the osg::ComputeBoundsVisitor does not consider the pivot position of 
the facing billboard. For example, let say I have a simple model that contains 
a single facing quad billboard (like a tree) located at (20, 20, 0) with a 
dimension of (10, 0, 10). I would expect the osg::ComputeBoundsVisitor to 
calculate a scene bounding box of min(15, 20, 0) max(25, 20, 10). However, what 
I seem to get instead is min(-5, 0, 0 ) max( 5, 0, 10 ). 

My investigation led me to review osg::ComputeBoundsVisitor and I found that it 
does not consider billboards - i.e. the 
osg::ComputeBoundsVisitor::apply(osg::Billboard& billboard) is missing. In 
effect, the osg::ComputeBoundsVisitor does not consider the pivot position 
stored in osg::Billboard::_positionList.

Is this design intentional? If not, then how would you propose fixing this 
issue?

Thank you!

Cheers,
Guy

Hi Nick,

   I also tried the Autodesk website and the links they provide are broken and 
taking you to a "page not found" default now.   I did send their support people 
and email letting them know that it was broken.  Hopefully they will fix it 
soon.

Cheers,
Curtis
