Hi,<div><br></div><meta charset="utf-8"><div>I'm batch processing vtk files containing a model of ours, adding sources/objects based on x,y,z coords, and then rendering/saving the field of view (fov) as pngs. I want some 2-d text labels (i.e. sm.sources.text() ) to "follow" the added objects as they move through my fov. (A good analogy would be labeling planets in a solar system simulation as they orbit the sun.) I was hoping to avoid having to do the whole set of geometry calculations to translate camera(x,y,z) and object(x,y,z) into an fov(x,y) for text positioning. If I use 3D text then I can use the object(x,y,z) but then I'll need to get the text orientation correct so that it's in the plane of the fov again...</div>
<div><br></div><div>Is there an easier way to add labels like this? Am I overlooking something obvious? </div><div><br></div><div>Many thanks!</div><div>Karl</div>
