   Hi,

   I'm looking for a batch command to render a k3d file. This is to automate an animation.
   I intend to use sed command to automate editing the k3d file, render it, and mail the result. The one thing I don't know how to do is the batch command to generate the image.

   Suppose the file is called myscene.k3d, and I want to render it into myscene.jpg or any other image file, what is the command I should use?

   FYI, I run fedora 13 Linux

   Thanks a lot!!!

   The way I'd handle this is via Python scripting ... K-3D 0.8 includes a script, <prefix>/share/k3d/scripts/shell/batch_render.py that could be modified to suit your needs. A simple (and untested) example would be to create a script "myscript.py" along the lines of

   #python
   import k3d
   document = k3d.open_document(k3d.filesystem.native_path("/path/to/myscene.k3d"))
   output = k3d.filesystem.native_path("/path/to/myscene.tiff")
   camera = k3d.node.lookup_one(document, "Camera")
   render_engine = k3d.node.lookup_one(document, "RenderMan Engine")
   render_engine.render_camera_frame(camera, output, False)

   and run it with

   $ k3d --ui=none --script-file=/path/to/myscript.py --batch --exit

   Cheers,
   Tim
