Hello,
how can I map a rectangle in my osg world on a rectangle with the same
size in a Video? The Video is behind the OSG Scene.
Cheers,
David

Hi Chris,
the osc-plugin compiles fine on my end with VS 2005. Is this a 64bit build?

Hi Mateo,
I'm a bit confused as to what you are actually doing, my best guess is
that it's something like shadow mapping. The best place to start is
to have a look at the osgprerender example and others similar to it.
Have a look at all examples that use osg::Camera when doing render to

Hello,
I implemented the example from the book OSG3 Cookbook where is described
how to play a Video in background of a 3D Scene. There they used
POST_RENDER to achieve the behind effekt. Is it so possible to use BLEND
in this setup, so that a 3D Object is semitransparent to the Video ?

Hi Rishabh,
The ref_ptr is smart pointer that will automatically manage the ref
and unref of OSG objects, and when the ref() count of these objects
goes to 0 they will be automatically deleted. If an object is shared
then it's ref count will be 2 or more (one per reference) and will not

Hi Simon,
I'm just adding a reply for completeness as I believe the build issue
was just a temporary glitch should have been resolved already (back
last year :-).
Could you test out the latest svn/trunk just to confirm that it's now OK?
Thanks,
Robert.

Hi Kevin,
From the scant details provided I don't see how others can guess at
what the issue might be. The type of difference between the two
images could one of many different things, the code segment or
description doesn't provide any clues to which of these it might be.
Have you got further
Hi Michael,
BIND_PER_PRIMITIVE is indeed a really poor way to drive the OSG/OpenGL
as modern OpenGL doesn't support this binding directly to the OSG has
to jump through hoops to recreate this feature. Moving to
BIND_PER_PRIMITIVE would be provide better peformance so you have my
blessing if you

The old .osg format won't support osgManipulator NodeKit, have you
tried the modern replacement .osgt that leverages the new serializer
support?

Hi Peterakos,
The bulk of the OSG loaders assume that world coordinates have +ve Z
upwards, +ve Y north and +ve X to the east.
The majority Camera Manipulators assume the world has Z up as well,
then set up Camera's view matrix so the Z up aligns with vertical
access of the screen, +ve Y into

Have you come up with a fix? I have plenty of stuff to get through so

Hi David,
If you want to blend the 3D objects ontop of a background image/video
then the best way would be to change the background Camera RenderOrder
to PRE_RENDER and disable the clear of the colour buffer for the main
Camera so that is doesn't overwrite the background.

my virtual camera so that their

Thank you Jeremy I'll have a look at that implementation (I was actually just

I'll also try compiling osgPPU and osgCompute and go through some examples to
assess which of these can accomplish what I am looking to do.

Well, my New Years resolution of publishing more stuff so far has fallen
flat on its face. :(
I have a whitepaper detailing how (I think) VPB/OSG/PagedLOD structures,

haven't polished it up and published it yet. Soon...
Also,
We're working on updating our builds as well, which will include the
COLLADA loader, if we can ever get it to compile. ;)
