[osg-users] Synchronizing with textures uploads.

[Altin Gjata]

Thanks for the hints Laurens. 

Indeed, I don't use DYNAMIC. I did in the beginning, but then I read that it hurts performance and commented it. This is the fragment of code:

Code:

			bg_image_quad_ = createTexturedQuadGeometry(osg::Vec3(), width, height, image, true, true, false);
			if (auto state = bg_image_quad_->getStateSet()) {
				// as explained here: http://forum.openscenegraph.org/viewtopic.php?t=9004
				// DYNAMIC has effect only when applied to StateSet or Drawable
				// apparently DYNAMIC hurts performance, as said here:
				// https://wiki.openmw.org/index.php?title=Rendering_Architecture
				//state->setDataVariance(osg::Object::DYNAMIC);
				//if (osg::ref_ptr<osg::Texture> texture = dynamic_cast<osg::Texture*>(state->getTextureAttribute(0, osg::StateAttribute::TEXTURE))) {
				//	if (auto myImg = dynamic_cast<ImageStream*>(texture->getImage(0))) {
				//		//texture->setDataVariance(osg::Object::DYNAMIC);
				//	}
				//}
			}
			bg_image_camera_ = create_display_image_camera(*this, bg_image_quad_, true);




I'll try in these directions.

Thank you again.

Cheers,
Altin
