import multiple files and arrange them


I am new here, but i want to say that i am happy to see that Blender supports scripting. I’m still figuring out, what the possibilities are. I’m used to program in the language called Processing.

i want to import vrml files to a enviroment and rotate them around a circle 360 degrees. I’m working with 851 vrml97 files and want to categorize them and view them in the game engine.

Another question i want to ask is what are the possiblities with xml databases?

I’ve found these codes

""" Registration info for Blender menus: 
Name: 'VRML batch loader'
Blender: 237 
Group: 'Import' 
Tooltip: 'Loads all .wrl files from a user defined folder' 
# Author Ewout                                     - Version 1.0 -  5 Aug 05
# Using Blender file dialog: b2b revision by Ewout - Version 1.1 - 16 Aug 05
# The purpose of this script is to automatically load wrl (VRML) files,
# saved out from Solidworks assemblies as individual part files, from a
# source folder.When finished loading save as .blend before continuing.
# Depending on the source of the VRML files, you may have some empty files,
# which results in a message from blender: "ERROR: Found no data"
# just keep your mouse moving and ignore this message :o)

import Blender
import sys
import os
print "loading script"

filename = ""

def f(name): # file selector callback
  global filename
  filename = name

  path = Blender.sys.dirname(filename)
  ext = '.wrl'
  print "Searching " + path
  for filename in os.listdir(path):
     if filename.endswith(ext): #check to make sure its a wrl file
       Blender.Load(path + "/" + filename)
  print "finished"

Blender.Window.FileSelector(f, "Open files in this dir")

import math
import Blender
import Blender.NMesh 

cam = Blender.Object.Get("Camera")
loc = cam.loc
rot = cam.rot

obj = Blender.Object.GetSelected()[0]
me = Blender.NMesh.GetRawFromObject( )

dd = 1.0
x = loc[0] - dd * math.cos(rot[0]) * math.sin(rot[2])
y = loc[1] + dd * math.cos(rot[0]) * math.cos(rot[2])
z = loc[2] - dd * math.sin(rot[0])

obj.LocX = x
obj.LocY = y
obj.LocZ = z

me.transform( obj.matrix )


t_pos = ( Blender.Mathutils.Vector(0, 0, -1) * cam.matrixWorld )

something like this:

And after that i want to automate the positions of camera’s. When pushing the left or right button it switches from position.
