Rendering Swiss PDB Viewer Images with POV-Ray in 8 Easy Steps

1. Download and install POV-Ray program: http://www.povray.org/

2. Allocate a LOT more memory (than default setting) to the POV-Ray program: something like 200 Mb. Otherwise, the program will crash while rendering.

3. After using PDB Viewer to create an appropriate image, save the image:

- as a Layer (give it a new name; this will be a .pdb file saving the current display options)

- as a POV-Ray 3 Scene (.pov file; make sure no background tasks [like printing] are occurring, as this has been known to corrupt the file)

4. Start POV-Ray, and open the .pov file (a text box will then appear, with some diagnostic data)

5. Under “Edit”, choose “Render Settings

- at the Quality tab:

- at the Output tab:

6. Under “Render”, click “Start Rendering

- ignore this error message: warning: degenerate triangle: please remove

- after processing .pov file, will draw big window and make very low-resolution rendering, followed by the high-resolution final product

7. Be VERY patient; rendering can take a LONG (perhaps >20 min) time to complete

- the program will make a distinctive tone when rendering is complete

- while rendering, you can move the sliders to see the (larger than screen-size) image being rendered

8. File is automatically saved as .pict (PICT) file with same root name (& in same directory) as .pov file. You can save it again, manually, with a different name, if desired

9. Try opening the .pict file in Canvas or Photoshop, to see if it looks like what you want (maybe try printing a hard copy, too)

- if it does not look right, go back to layer file (.pdb) and tweak

- N.B.: POV-Ray images often appear darker than the on-screen PDBViewer image
