How to make transparent geometry located at various osg:: Drawable properly

properly sorted is difficult.
OSG sorts the geometry by the distance from the camera.
This leads to incorrect results.

Hi Thomas,
One shouldn't mix primitives that will have some form of alpha
blending with opaque ones in the same osg::Drawable/osg::Geometry
leaves, as the depth sorting of the transparent bin is done at the
Drawable level. However, it doesn't matter how you group the Drawables

Hi,
When I only have one point in a GL_POINTS DrawElements primitive, the shaders
in my StateSet have no effect. It seems a primitiveset cannot contain use only
one point, or the point does not reach the shaders for some reason.
To reproduce the problem, change the osggeometryshaders sample so
Hi Fred,
My guess is that small feature culling is culling the Geometry before
it even gets into the draw traversal. You can switch off small
feature culling by doing:
viewer.getCamera()-setCullingMode(viewer.getCamera()-getCullingMode()
~osg::CullSettings::SMALL_FEATURE_CULLING);
Robert.
Thanks for the replay!
Another question how can I know the hardware limit vertex attributes?
Thank you!
Cheers,
Aitor

Hi all
I'm trying to push the IPhone fps to the limit, at moment I can render
10,000 + triangles with diffuse/normal/reflection mapping at 30 fps but I
think we can squeeze a lot more out of it. So i'm writing a node visitor
which could eventually be added to the optimizer to remove all un used
Hi Tom,
The CPU cost of depth sorting the transparent objects is pretty low,
and will only be significant if you have a very large number of
geometries that need to depth sorted.
Do you think you are CPU limited by the sorting of transparent bin?

Hi Robert
At the moment I'd say my scene isn't complex enough to really tell,
everything is in one location and there aren't many geodes. Main reason I'm
looking into it is the apple docs state that it's a waste of cpu to depth
sort and I'm just looking for all the extra performance I can find

Just a little heads up for anyone using fbx plugin with fbx sdk 2011.2. I

But for some reason the fbx sdk 2011.2 sets the eUpVector enum in

Hi,
Small piece of code:
Code:

verts-push_back(osg::Vec3(-100.0f, 200.0f,-100.0f ) );
verts-push_back(osg::Vec3( 100.0f, 200.0f,-100.0f ) );

Hi Robert,
DrawElementsUInt can make use of std::vector methods directly, such like:
osg::DrawElementsUInt* de = new
osg::DrawElementsUInt(osg::PrimitiveSet::LINE_LOOP);
de-push_back( 0 );
de-push_back( 1 );
de-push_back( 2 );
Or
de-resize(3);
(*de)[0] = 0;
(*de)[1] = 1;
(*de)[2] = 2;

Sounds sensible to me. I'm just a little too keen. All in all though I've
been really impressed by the performance already. I'll start making a test
scene and perhaps add a few features that can be toggled, like render to
texture etc. I'll see if I find time this weekend

In the current trunk in include/osgText/Text it looks like the first
definition of setEnableDepthWrites() should be getEnableDepthWrites()
instead.
bool setEnableDepthWrites() { return _enableDepthWrites; }
void setEnableDepthWrites(bool enable) { _enableDepthWrites = enable; }

Hi Ken,
This is a mistake, thanks for spotting it. I've fixed this and
checked it into svn/trunk.

I think i've pinned it down to the fact the context isn't actually ready on
