Before starting to spend money, do you think about spending as little money as possible to begin with? That’s where “DAVID” comes in.

Who is DAVID?

It is not me or my brother!

It refers to “Definitely Affordable VIsion Device”. It allows you to do three-dimensional laser scanning on the cheap – and I mean  cheap!

To get started you need:

A laser level from a DIY shop.
A tripod.
A web cam
A cardboard box

There is a youtube video which shows you how.

When you have watched this video, download the trial version of DAVID at:
http://www.david-laserscanner.com/?section=Downloads

Set up your apparatus as indicated in the video.

Caveats:

The trial version of DAVID3  allows you to fuse scans into a three dimensional object by scanning the front, back, and the sides of an object, but it does not allow you to save the fused result.

You can get around this by using the freeware program “Meshlab”. There is a youtube video on this subject as well.

Another freeware program useful in this context is Netfabb.

The bloke on this web page says “Nostalgia. Boredom. Narcissism. These are all excellent reasons to make an action figure of yourself”.   This tutorial is interesting in that it shows you how to use the freeware programs Netfabb and Meshlab.

Bigex

Do you want to create your own Railway Stations and signal boxes for use in Railworks using Freeware tools?

Then you need

Blender, Python, and Bigex.

What is “Bigex”?

Bigex is a Python script which is activated from Blender, from the file, export menu.

Bigex runs under

either Blender 2.48 and Python 2.5

or Blender 2.49 and Python 2.6

Tip: on Windows, you can have both versions of Blender, and both versions of Python on the same machine, but you need give one of the “Blender Foundation”  folders different name e.g. “Blender Foundation Old Version”

To have the old version of Python on the same machine, you need to set an environment variable setting a path to the old version of Python.

Set-up a Python Path

I have found the older version of Blender not to be compatible with Vista. However, on Linux, this is a consideration which does not apply.

The Linux version of Blender is slightly better in that Linux gives you more control over the size of menus and the appearance of the screen. On Windows, some items appear too small to read on a laptop. This consideration would not apply if you are using a Desktop and a large screen.

Where do you get Bigex?

It is available from UK train sim.

Issue

Open Shot does not work with blender  when creating animated titles. You get the following error:
No frame was found in the output from blender

Why would anybody care?

“OpenShot” is a marvelous FREE video Editor for Linux which is similar in function to “Windows Movie Maker”. It allows you to create 3-dimensional animated titles when used in conjunction with blender.

What is “blender”?

Blender is a marvelous FREE 3-dimensional modelling an animation program.  There is a steep learning curve, but it’s FREE.

Well, to cut a long story short, you want to get OpenShot and Blender working to make all those fancy 3D animated titles on your YouTube submissions. Right? Here’s how:

Resolution:

Got to the terminal and copy and paste the following from here:

sudo add-apt-repository ppa:jonoomph/openshot-edge
sudo apt-get update
sudo apt-get install openshot openshot-doc
sudo add-apt-repository ppa:cheleb/blender-svn
sudo apt-get update
 sudo apt-get install blender

Installing by this method will put the latest version of blender on your pull down menu under graphics.

You now need to change instances of “CENTRAL” to “CENTER” in an XML set-up file.
for 32 bit Ubuntu type the following on the command line:
sudo gedit /usr/lib/pymodules/python2.6/openshot/blender/*.xml
For 64 bit Ubuntu:

sudo gedit /usr/lib64/pymodules/python2.6/openshot/blender/*.xml

Now in gedit hit “Control-H”, this will pop up a replace dialog.

Search for “CENTRAL”
Replace with “CENTER”

There are three instances to be replaced. Save the file and close.

Now, open up the Synaptic package manager and install:

libavutil-dev

If your current version of blender still does not work with your current version of OpenShot, install version 2.59, which is here.

http://download.blender.org/release/Blender2.59/

Install the version for your operating system. For 32-bit Ubuntu, this is:
http://download.blender.org/release/Blender2.59/blender-2.59-linux-glibc27-i686.tar.bz2

When you download this, choose “open with archive manager”, and extract the archive to your  Home folder (or any other folder you find convenient)

Fire up Open Shot:

In the OpenShot preferences, enter the path to the blender execuable:

e.g. /home/yourname/blender-2.59-linux-glibc27-i686/blender

If your name is “Fred” then it would be
/home/fred/blender-2.59-linux-glibc27-i686/blender

You can have two versions of blender on the machine at the same time. If your latest version of  blender is in your “applications” folder, the path is “/usr/bin/blender “.  If version of blender you have got in your applications “usr/bin” folder is the version which works with blender, then you can use that.

Currently, Openshot  1.4.0 works with blender 2.59, and Ubuntu 10.10. I know, because I just got it to work!

These instructions will also work for Linux Mint 10. I am now using this Distro.
