Dear icf80, thanks for your reply. Yes, you are right. the cube is created by hand, and the camera is too. I will make a try as you suggest. thanks for your help again. ... Thank you!

Re: [osg-users] Transparency problem
Hi, - your cube might have wrong triangles/vertices order. Did you create the cube by "hand"? - have you modified the cull settings? The triangles with back face towards the camera need to be culled. - did you create your own camera? Thank you!

Re: [osg-users] Transparency problem
Hi,
This might help you, you have to set the hint
Code:
if (transparent)
{
geode->getOrCreateStateSet()->setMode(GL_BLEND,
osg::StateAttribute::ON);
geode->getOrCreateStateSet()->setRenderingHint(osg::StateSet::TRANSPARENT_BIN);
}
else
{
geode->getOrCreateStateSet()->setRenderingHint(osg::StateSet::OPAQUE_BIN);
}
Thank you!
Cheers,
Catalin

[osg-users] Transparency problem
Hi, Everyone! Is there anybody can help to solve this problem. I tried to make
geode node to be transparency in my application. A piece of my code is list
below:
osg::StateSet* stateSet = geode->getOrCreateStateSet();
stateSet->setMode(GL_BLEND, osg::StateAttribute::ON |
osg::StateAttribute::OVERRIDE);
osg::BlendFunc* blendFunc =
dynamic_cast(stateSet->getAttribute(osg::StateAttribute::BLENDFUNC));
if (nullptr == blendFunc) {
blendFunc = new osg::BlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA);
stateSet->setAttribute(blendFunc, osg::StateAttribute::ON |
osg::StateAttribute::OVERRIDE);
} else {
blendFunc->setSource(GL_SRC_ALPHA);
blendFunc->setDestination(GL_ONE_MINUS_SRC_ALPHA);
}
osg::Material* mat =
dynamic_cast(stateSet->getAttribute(osg::StateAttribute::MATERIAL));
if (nullptr == mat) {
mat = new osg::Material;
stateSet->setAttribute(mat,osg::StateAttribute::ON |
osg::StateAttribute::OVERRIDE);
}
mat->setAmbient(osg::Material::FRONT_AND_BACK,osg::Vec4(0.2f,0.2f,0.2f,0.3f));
mat->setDiffuse(osg::Material::FRONT_AND_BACK,osg::Vec4(0.8f,0.8f,0.8f,0.3f));
mat->setTransparency(osg::Material::FRONT_AND_BACK, 0.4);
osg::LightModel* lm = dynamic_cast(stateSet->getAttribute(osg::StateAttribute::LIGHTMODEL));
if (nullptr == lm) {
lm = new osg::LightModel();
stateSet->setAttribute(lm,osg::StateAttribute::ON |
osg::StateAttribute::OVERRIDE);
}
lm->setTwoSided(false);
stateSet->setAttribute(lm, osg::StateAttribute::ON |
osg::StateAttribute::OVERRIDE);
it seems like something is wrong as the transparency effect is miss-up. could
anybody figure out what i missed and how to solve this problem.
thanks very much for your help!
Cheers,
Yu

Re: [osg-users] Transparency problem
So the solution to the transparency sorting problem is simply to separate the objects with transparency and those without?

In my case, trees (transparent) and some terrain (opaque) parts were in the same object : that give rise to sorting problems between the trees and the very parts of terrain.

Re: [osg-users] Transparency problem
Hi Paul and Robert, What you are saying makes sense indeed, I didn't think about that. I will check that inferring (the database is large and exported from 3DSMax using OSGExp) : maybe OSGEXp suffer of some lackings concerning transparency issues indeed. Maybe I have after loading of the .osg (or .ive) to make a quick pass on the scenegraph to isolate the TRANSPARENT_BIN affected geometries to associate some of them to another (of greater number) bin. I'll make further inquiries to check that point and see. I'll keep the mailing list informed of the conclusion cos it may be of interest for others.

The strings are in front of a semi-transparent rectangle in front of the semi-transparent window. What might be happening? Hi!

Re: [osg-users] Transparency problem
Hi Andreas. Well I have already tried to change the stateset of the geode of the osgText for example with something like stateSetGeode-setRenderBinDetails(15, RenderBin, osg::StateSet::OVERRIDE_RENDERBIN_DETAILS) , but it doesn't seem to help. The bigger the renderbin the later it is rendered in the scene, right? Panagiotis Papadakos On Thu, 27 Sep 2007, [EMAIL PROTECTED] wrote: Hello everybody. I have a transparency problem which you can see in the attached image. As you can see the strings rendered on the orange window, which is in front of another blue window, have a blue outline from the blue window behind. The strings are in front of a semi-transparent rectangle in front of the semi-transparent window. What might be happening? Hi! I had the same problem with billboards and I fixed it with setting the stateset's RenderBinNumber. RenderBins in OSG is used to specify which objects are going to be drawn first. -- Andreas Richter ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
