Complex B&W outline representation What To Type

Description
Making a B&W outlined image with depth.

# When you have the scene set like you want,
# continue with...

# move the model to find the view you want, 
# and use get_view to get the coordinate description
get_view;

# set ray_trace_mode to black and white outline
set ray_trace_mode, 2;
Now, you'll need to save multiple versions of your model. (use ray, then png <filename> to save each version)
  1. Version A: with all the elements except for the helix. This will become the background.
  2. Version B: with the 'front' elements, and the helix. Basically this is just a few 'layers' of lipid, with the helix among them. To do this:
    1. move the model around until you visually see the part to remove
    2. switch your Mouse Mode to 3-button viewing, then use the +Box selection (Shift+Left mouse) to select the 'background' portion to hide.
    3. choose Hide>Everything for the selection
    4. use the code from get_view to go back to the original view
Finally, you will need to compose the image in Photoshop (or Gimp, here I'll use Photoshop).
  1. Load the two versions.
  2. Select the white background in Version B, then choose Select>Color Range...
  3. Make sure 'Select' is set to 'Sampled Colors', and 'Fuzziness' is set to 150, then click okay.
  4. delete the white selection, then choose Select>All
  5. copy the picture, then switch to Version A and paste the selection (it should paste into its own layer as 'Layer 1')
  6. Click on 'Layer 0' (which is Version A) and change its opacity to 30%
  7. Create a new layer under 'Layer 0' which is filled with white only (or whatever background color you like)
  8. Click on 'Layer 1' (which is Version B), and using the Move tool (and nudge), align the molecules in 'Layer 1' to 'Layer 0'
  9. Some parts of 'Layer 1' are transparent and shouldn't be. Using the Paint Bucket tool fill in these areas with white (or whichever color you find appropriate).
  10. Admire your handiwork; put it in a publication, presentation, or poster.



A "Sliced" Image What To Type

# this controls the z depth of the slice plane
# (sets it halfway between the clipping planes)
fraction = 0.42
view = cmd.get_view()
near_dist = fraction*(view[16]-view[15])
far_dist = (view[16]-view[15]) - near_dist
