Hey Everyone,
Can anyone explain the significant differences between using an LOD that has
many ProxyNode children for paging vs. a full PagedLOD node? Right now, the
biggest benefit that I see for PagedLOD nodes is that they'll continue to
shower lower quality children until the next higher
Hey Everyone,
I saw a recent post on these boards asking how to control render order
for huds using render bins, and I was curious if the same can be done
for general subgraphs in a larger scene.
I'm placing a sign into my scene using a Billboard with some drawables.

Hey Everyone,
I've been trying to emulate a fade to transparent effect (think of a
linear fog that works on alpha, not color) using a 1D texture with 2
texels, 0 = opaque, 1 = transparent. My problem is with generating the
texture coordinates
I thought I could use a texgen with EYE_LINEAR
In trying to solve my texgen issue, I decided to play with the texture1D
example. I noticed that it defines an AnimateStateCallback which is
supposed to toggle the texgen mode between OBJECT_LINEAR to EYE_LINEAR
every second. Whenever I run the example on cow.osg, the texture seems
fixed regardle
See the
OpenGL docs for glTexGen.

Can TexGens and TexGenNodes reuse texture units? My scene graph is
setup with many distinct elements that need individual texture
coordinate generation, but if I try to reuse a texture unit, texgen
fails.
My setup is as follows:
root->{
cube_group->{texgennode, geode},
sphere_group

Is there a way to use double precision vertex arrays with an
osg::Geometry? I didn't see an enum for Vec3d entries, but I wouldn't
doubt that the TemplateIndexArray provides some support.
Thanks for any info,

Hi Everyone,
I'm trying to control transparency of a subgraph from a high level, and
I though BlendFunc with BlendColor would be a good way to go.
Setting up the two with constant color = (1, 1, 1, opacity_scale) and
BlendFunc = (GL_CONSTANT_ALPHA, GL_ONE_MINUS_CONSTANT_ALPHA) allows me

Paul,
PagedLODs are registered as inactive when their frame count gets out of synch
with the overall viewer. Once they become inactive, their children are
released. In other words, if each child has an identical bounding sphere, none
of them will get freed until the lowest child is culled.

Unfortunately, that's just a limitation of the visitor pattern and
double dispatch in general. In order to accomplish what you want, you'd
have to overload apply(osg::Group) forward the call explicitly.
Something like:
MyVisitor::apply(osg::Group& grp)
{
if( dynamic_cast(&grp) )
apply( stat
You might be able to accomplish what you want by setting
text->setCharacterSizeMode( osgText::Text::SCREEN_COORDS ). That applies a
scale that warps the text into pixel coordinates, instead of object coordinates.

This doesn't really answer your question, but the bad sheering effect
you're getting might be solvable by apply the GL_POLYGON_SMOOTH
attribute to the text object.

If you have a transform tree, with the following:
A: translate (0, 10, 0)
|
---B: translate( 0, 5, 0 )
| |
| --- Model 1
|
---C: translate( 0, 20, 0 )
|
--- Model 2
Then A cannot be flatten with B and C, because B != C. If A, B, and C
were flattened into a single transform, then Model 1

I ran into this problem very recently too on a Win32 system. The solution I
had to adopt was checking the modifier keys using the Win32 API's GetKeyState
function when processing a key that's affected by modifiers.
I agree that it probably shouldn't be OSG's responsibility to account for this
