Hi yt users,
Hi there! I'm just starting to use yt to make volume renderings of FLASH simulations. While working through examples, I hit a roadblock, and I've had some difficulty finding good documentation on the what the "Scene.save()" function actually does; specifically, why it does different things on the first and second call. The first example in the user tutorial page for 3D volume rendering ( http://yt-project.org/doc/visualizing/volume_rendering.html) looks something like this:
... sc = yt.create_scene(ds, lens_type='perspective') ... source = sc source.tfh.set_bounds((3e-31, 5e-27)) ...
And, voila, volume rendering saved to png.
However, if I naively continue the script to re-render with new settings: source.tfh.set_bounds((3e-35, 5e-27)) sc.camera.zoom(2.0)
I find that none of my new settings are reflected in "rendering2.png" -- it's just a duplicate of "rendering.png"! But if I start again from scratch with a new scene, the settings take hold. This leaves me (a new user) scratching my head.
So here is my question: Once you've created and saved a scene once, how do you change scene settings like colormap and camera angle?
