Trying to install an alternate copy of python than that which ships with Centos5 (Why do these package installers not rpm or yum the latest version?? Please can someone tell me!).
The first is to run ./configure
Then if you run make it will break with make: *** [libinstall] Error 1
The solution then is to edit ./Modules/Setup.dist and comment out line 180
rerun with make altinstall to not make it the default.
Blender runs pretty well in a cygwin x-windows shell (so far anyway). Getting Blender to actually work on my generic Centos 5 install was excruciating.
To find out what is missing from a system that will prevent an application from running use ldd as in the following example for the blender executable
[root@styx blender-2.45-linux-glibc236-py24-i386]# ldd blender | grep “not found”
libopenal.so.0 => not found
libalut.so.0 => not found
libSDL-1.2.so.0 => not found
Then to install packages:
[root@styx blender-2.45-linux-glibc236-py24-i386]# yum install libSDL-1.2.so.0

Getting Blender working
The above mentioned package via, yum install libSDL-1.2.so.0
rpm -i /mnt/dante/everyone/openal-0.0.8-1.i586.rpm
rpm -i /mnt/dante/everyone/libalut-1.1.0-alt1.2.i586.rpm
I wanted a glass floor between two datacentres so I could see the servers in the room below also. I put a slight red tint in the glass for effect. The greens sphere and blue cube are sticking out from behind the slice of glass. Theres a rock thing in front of the glass. A lamp shines from above which is casting a shadow on a screen behind.
Warning to newbies:
Make sure to show the outliner and refresh when you have run the code. Can be a pain in the backside trying to apply materials etc. to objects. The outliner shows whats going on.

Where farm1 is a Blender object , a tuple is like an array of typed data
WLH = farm1.getSize()
print “WLH = ” , WLH # here we can see the list of reals
print “X is ” , XYZ[0] # which are returned in order x,y,z
x = – WLH[0] / 0.2
y = – WLH[1] / 0.2
Where farm1 is an instance of a blender object and the object name begins with the string ’seso’, farm1 is made the parent of all the objects
obs = [ob for ob in scn.objects if ob.name[0:4] == ’seso’]
scn.objects.selected = obs
for ob in obs:
print ob.name
farm1.makeParent(obs)
Two basic functions to create a camera and lamp
def newCamera():
cam = Blender.Camera.New(‘ortho’) # make ortho camera data object
ob = scn.objects.new(cam) # make a new object in this scene using the camera data
ob.setLocation (0.0, -5.0, 10.0) # position the object in the scene
def newLamp():
lamp = Blender.Lamp.New(‘Spot’)
ob = scn.objects.new(lamp)
ob.setLocation (0.0,-4.0,15)
