* '''Step 1'''
=== [[3. Joining Atoms]] ===
Load the PDB file 3IQS into PyMOL, duplicate it twice and rename the two new objects to "3IQS_cartoon" and "3IQS_surface" as shown in the image below:
 
[[Image:Scr01.png|center|350px]]
 
* '''Step 2'''
Turn off the display of "3IQS_surface" as shown below:
 
[[Image:Scr02.png|center|350px]]
 
* '''Step 3'''
Save the displayed "3IQS_cartoon" as a VRML file, as shown below:
 
[[Image:Scr03.png|center|350px]]
 
* '''Step 4'''
Hide the "3IQS_cartoon" and display the "3IQS_surface". Again, save the displayed "3IQS_surface" as a VRML file, as shown below:
 
[[Image:Scr04.png|center|350px]]
 
* '''Step 5'''
Start Blender (please see link in the Introduction to download and install). Assuming you are looking at the default scene and window layout, press '''7''' on '''numeric keypad''' and the view should change similar to the one below:
 
[[Image:Scr05.png|center|350px]]
 
Now select the '''cube''' in the center of the screen by '''right clicking''' on it and then press '''ctrl-x''' to delete it. This will give you a clean scene to import the protein structure you just exported from PyMOL as VRML 2 (.wrl).
 
* '''Step 6'''
Now import the "3IQS_cartoon" into Blender by going to "File > Import > X3D & VRML97" as shown below:
 
[[Image:Scr06.png|center|350px]]
 
* '''Step 7'''
Navigate to the folder where you exported the VRML 2 files from PyMOL and select the "3IQS_cartoon" file, thusly:
 
[[Image:Scr07.png|center|350px]]
 
Click the "Import X3D/VRML97" button after selecting the correct file and just click "OK" on the dialog that comes up.
 
* '''Step 8'''
Doing the above should result in a display such as the one below:
 
[[Image:Scr08.png|center|350px]]
 
* '''Step 9'''
Now you need to select the just imported cartoon and just that only, so '''right click''' on it so that it is the only object selected in the view:
 
[[Image:Scr09.png|center|350px]]
 
* '''Step 10'''
With the cartoon object selected, hit the '''Tab'' key on your keyboard to enter into "Edit mode" in Blender. All the vertices  that make up this object will be selected and colored yellow, as shown below:
 
[[Image:Scr10.png|center|350px]]
 
* '''Step 11'''
Now click on "Mesh > Vertices > Remove Doubles" in Blender to get rid of duplicate vertices, as shown in the two images below:
 
[[Image:Scr11.png|center|350px]]
[[Image:Scr12.png|center|350px]]
 
* '''Step 12'''
Now hit the '''Tab'' key again, to exit the "Edit mode" to see a nice smooth cartoon object:
 
[[Image:Scr13.png|center|350px]]


* '''Step 13'''
== Why Blender? ==
This cartoon is too big to be visible in the Blender's camera viewport while rendering, so we need to scale it down by hitting the "S" key once, then moving the mouse so that the object becomes smaller in size and then clicking the left mouse button to accept the new size:


[[Image:Scr14.png|center|350px]]
* Blender is FREE (as in beer)
* Blender is Open Source and therefore FREE (as in freedom)
* Blender is an extremely capable 3D graphics program and perhaps the only FOSS program capable of taking on similar commercial software head-to-head (Maya/Max/Modo etc.)
* To see some examples of what Blender can do check out:
** http://www.elephantsdream.org/
** http://www.bigbuckbunny.org/
** http://www.yofrankie.org/


The final size should be small enough to completely fit in the "Camera view" in Blender. You can enter the "Camera view" by hitting the zero '''0''' key on the '''numeric keypad'''. Scale the object so that it fits within the camera boundaries:

HELP! : Fellow Blenderheads please help improve this page!!!

Introduction

This is an attempt at using Blender, an open-source, free, 3D modeling software to render, pose and animate objects exported from Pymol.

Blender may be downloaded freely for all major platforms (Win/Mac/Linux), from: http://www.blender.org/download/get-blender/

A great starting place for getting comfortable with Blender is the Blender Wiki: http://wiki.blender.org/

These tutorials are for Windows.

Tutorials

Representative examples. Please change/improve.

1. Importing a PyMol Structure into Blender

2. Translucent Surfaces

High quality translucent surfaces, better than PyMOL's internal renderer/ray-tracer.

3. Joining Atoms

Why Blender?

Blender is a perfect complement to PyMOL for creating high quality images and animation, but has a pretty steep learning curve. The following are a few resources that may be of help along the way:
