============================
 Publication-quality images
============================

To make an image with AO (ambient occlusion lighting) and depth
cueing:

* Settings

  * Try if :menuselection:`Display --> Rendermode --> GLSL` works for
    you.

    This *should* work with most modern graphics cards that are OpenGL
    capable. Once VMD uses OpenGL, it will render everything much
    faster and the results will look much smoother than with the
    standard (not accelerated) setting. However, if you cannot display
    certain representations (e.g., VDW) then unset this setting again.

 
  * :menuselection:`Display --> Display Settings`: 

    - Shadows On, 
    - Amb Occl On
    - Cue Mode: Linear 
    - Cue start: 1.75
    - Cue end: 3.0
          
  * white background: :menuselection:`Graphics --> Colors: Display : White`
  
* rendering: :menuselection:`File --> Render`

  - *snapshot*

    - glossy material looks nice

  - *tachyon (internal)*: ray tracer (takes a while due to AO)

    - change materials to special AO materials (e.g. AOChalky)

.. figure:: /images/dims_vdw.jpg

   Example (AdK) was rendered with Tachyon (internal) with VDW
   representation, colors silver, yellow, and blue, no depth cueing,
   material AOChalky, and using Ambient Occlusion (AO) and Shadows
   (see :menuselection:`Display --> Displaysettings`)
