[osg-users] UpdateCallback

[Julie Green]

Code:

void UpdateSurfaceCallback::operator()(osg::Node *node, osg::NodeVisitor *nv)
{
	osg::Geometry* geometry = node->asGeometry();
	osg::Array* vertices;
		
	if (geometry)
	{
		vertices = geometry->getVertexArray();
	
	int N = vertices->getNumElements();
	osg::Vec3Array *array = new osg::Vec3Array(N);
	array = dynamic_cast<osg::Vec3Array*>(vertices);

	for (int i = 0; i < N; i++)
	{
		delta = ((*vertexArray)[i].z() - (*array)[i].z()) / 1000;
		dz = (*array)[i].z() + delta*c;
		(*array)[i].set(osg::Vec3f((*array)[i].x(), (*array)[i].y(), dz));
	}
	c++;
}
	traverse(node, nv);

};
