Hi,
I'm having a crash with setTextureAttributeAndModes I don't know how to fix.
To explain the issue. I have a list of data sets which hold a pointer to a
osg::Texture3D. The texture mixing is done in a shader and my texture update
function containing the following loop is called from an update callback.
Since the order of the textures can/must change i loop over the textures and do
this
Code:
osg::StateSet* sliceState = m_sliceNode->getOrCreateStateSet();
for ( size_t i = 0; i < datasetList.size(); ++i)
{
osg::Texture3D* texture3D = datasetList[i] )->getTexture3D();
sliceState->setTextureAttributeAndModes( i, texture3D,
osg::StateAttribute::ON );
}
This works just find when adding one texture after another. However when the
order changes, thus overwriting a different order it crashes. So apparently I'm
doing it wrong.
Any help would be greatly appreciated.
...
Thank you!
Cheers,
Otto
