Hello,
today I have tried to make use of the MultiCore core. Below you can see
the modified createScenegraph function from the 07materials tutorial.
#ifdef OSG_BUILD_ACTIVE
#include <OSGMultiCore.h>
#else
#include <OpenSG/OSGMultiCore.h>
#endif
OSG::NodeTransitPtr createScenegraph(void)
{
OSG::NodeRecPtr root = OSG::Node::create();
OSG::MultiCoreRecPtr multi_core = OSG::MultiCore::create();
root->setCore(multi_core);
OSG::SimpleMaterialRecPtr simpleMaterial =
OSG::SimpleMaterial::create();
simpleMaterial->setDiffuse(OSG::Color3f(1,0,0));
simpleMaterial->setAmbient(OSG::Color3f(0.2, 0.2, 0.2));
simpleMaterial->setTransparency(0.0);
OSG::NodeCoreRecPtr sphere = OSG::makeSphereGeo(2,6);
OSG::MaterialGroupRecPtr mg = OSG::MaterialGroup::create();
mg->setMaterial(simpleMaterial);
multi_core->addCore(mg);
multi_core->addCore(sphere);
return OSG::NodeTransitPtr(root);
}
This does not work, i.e. the material is not respected. So either my
expectation about the MultiCore is wrong or a subtle error is at work.
So, how do I correctly use the MultiCore core?
Best,
Johannes
