Tweaking your own Latex template for a PhD dissertation is a rite of passage/time waster for most PhD candidates. There are lots of templates around on the Internet too, of varying quality.

I spent a fair bit of time procrastinating perfecting the template used for my thesis. I’ve pulled out all the unnecessary bits and put it up on GitHub. Hopefully some other poor PhD student will find it useful. This template is itself based on styles developed by Peter Hutterer, an earlier PhD student from the Wearable Computer Lab.

This template is particularly suited to students at the University of South Australia. It meets the guidelines specified by the Graduate Research Office. That said, with some adjustments this template should be useful for anybody.

Features:

  • Nice cover page
  • Author’s publications
  • Acknowledgements
  • TOC, List of Figures, Abbreviations, etc.

How to use:

  • Fork and clone the GitHub repository
  • Edit the information in thesis.tex
  • Update images/00/author_sig.png with your own signature
  • Update images/00/uni.png with your university’s logo
  • Add your publications as citations in 00-publications.tex
  • Tweak the styles as necessary
  • Write your damn thesis!

I’m happy to accept Pull Requests for improvements on this template.

Check it out on GitHub!

Happy Writing!

Here’s a quick post to show off the tiled projector display calibration I have implemented.

Please note: I did not invent this! What you see is more or less an implementation of the algorithm described here:

800px LaTeX logo svg  e1308095178677 I’m currently in the early stages of writing my PhD thesis. I’m writing it using LaTeX, and I’m trying to get the perfect build system and editing environment going. Yesterday I had a look at Texlipse, a plugin for Eclipse. There was one problem: EPS figures didn’t work.

In newish versions of Latex, if you use the epstopdf package, your images are converted on the fly, but this wasn’t  working in Texlipse. Luckily the fix is easy, and the rest of this post explains what to do.

Lets start with a minimum working example to demonstrate the problem:

\documentclass{minimal}
\usepackage{epsfig}
\usepackage{epstopdf}
\usepackage{graphicx}

\begin{document}

Here's an EPS Figure:

\includegraphics[height=5cm]{unisa}

\end{document}

Download unisa.eps, and try this yourself. On Ubuntu, I get output that looks like this:

eps broken

Broken PDFLatex output on Ubuntu

If you look at the console output generated by TexLipse, you will see one of two problems, described below.

Problem 1: Shell escape feature is not enabled

I encountered this problem on Ubuntu. If you see the following output:

pdflatex> Package epstopdf Warning: Shell escape feature is not enabled.

Then you have encountered this. The fix is quite easy.

  1. Open up Eclipse Preferences
  2. Click on Texlipse Builder Settings
  3. Click on PdfLatex program, and press the edit button
  4. Add –shell-escape to the argument list as the first argument.
  5. You’re done! Rebuild your project and it should work fine.

Problem 2: Cannot Open Ghostscript

I encountered this problem on OSX. Weird how the two systems have the same symptoms with different causes, but whatever. If you see the output:

pdflatex> !!! Error: Cannot open Ghostscript for piped input

Then you are suffering from problem 2. This problem is caused by the PATH environment variable not being set correctly when Texclipse runs pdflatex. Essentially, the Ghostcript program, gs, cannot be found by pdflatex. The fix is to add an environment variable to Texlipse’s builder settings so the path is corrected.

Step 1: Locate Ghostscript, Repstopdf, and Perl

Open up a terminal, and type:

which gs

This should show you the directory where Ghostscript lives on your system. On my laptop it is:

/usr/local/bin

Repeat the process with repstopdf:

which repstopdf

Which on my system gives:

/usr/texbin

And with perl:

which perl

gives me:

/opt/local/bin

The exact paths will depend on how you have installed these things. For example, Perl lives in /opt on my system because I installed it using macports. It doesn’t really matter. However, if you don’t have any of these packages installed, you will need to do so.

Step 2: Create the Environment Variable

Now that we know where the programs are installed, we need to create a PATH environment variable for Texlipse to use.

  1. Open up Eclipse Preferences
  2. Go down to Environment, which is under Texlipse Builder Settings
  3. Click new to create a new environment variable
  4. the key should be set to PATH. The value should be the three directories, separated by colons (:). For example, on my system:
    add environment variable
  5. You’re done! Save the settings and everything should work.

Conclusions

If you complete the steps above, depending on what problem you had (you may have even had both), then you should see the correct output, which looks like this:

eps fixed
EPS Figure working!

Well, I hope that helps someone. Its surprising that this error came up on both of my computers. Searching the internet finds others with the same problem, but as yet no solutions. This post should fix that.

Hey Everyone

So right now I am at the IEEE Symposium on 3D User Interfaces in Singapore. We have a couple of publications which I’ll be posting over the next few days. First up is Adaptive Color Marker for SAR Environments. In a previous study we created interactive virtual control panels by projecting onto otherwise blank designs. We used a simple orange marker to track the position of the user’s finger. However, in a SAR environment, this approach suffers from several problems:

  • The tracking system can’t track the marker if we project the same colour as the marker.
  • Projecting onto the marker changes it’s appearance, causing tracking to fail.
  • Users could not tell when they were pressing virtual controls, because their finger occluded the projection.

We address these problems with an active colour marker. We use a colour sensor to detect what is being projected onto the marker, and change the colour of the marker to an opposite colour, so that tracking continues to work. In addition, we can use the active marker as a form of visual feedback. For example, we can change the colour to indicate a virtual button press.

I’ve added the publication to my publications page, and here’s the video of the marker in action.

This weekend I presented my paper, Augmented Foam Sculpting for Capturing 3D Models, at the International symposium on 3D user interfaces. Since the conference has passed, I have added the video to youtube and the paper to my publications page. First, the video, then some discussion after the jump.

Foam Sculpting

The inspiration for this work came out of a project we did with some industrial design students. Their job was to create some input devices for my SAR Airbrushing system. First up, we had a  meeting where I showed them a very early stages of development version of the system, to give them an idea of what we were doing. They went away and came up with ideas for input devices, and in the next meeting had a bunch of sketches ready. We discussed the sketches; what we liked and what we didn’t like. Next, they brought us foam mockups of some of the designs. We discussed these, and then eventually they came back with full CAD models ready for 3D printing.

They did a great job by the way. But it got us thinking:

How can we make this process better?

Augmented Foam Sculpting is the result of this work. It allows a designer/artist to simultaneously create a physical design mockup and matching virtual model. This is a Good Thing™, because it utilises the skills and tools that designers are already using.

Tracked foam and foam cutter

The system works by tracking the position and orientation of both the hot wire foam cutter, and the piece of foam the user is sculpting. We can track the motion of the hot wire as it passes through the foam.

From there, we can create geometry that matches the cut path, and perform a Boolean difference operation on the foam geometry.

This replicates the cut in the physical object in the 3D model .

Using projectors, we can add extra information to the foam as the user sculpts. We implemented 2 visualisations to aid designers when creating specific models.

Cut Animation displays cuts to be made as animated lines on the foam surface. Once a cut has been made, the system moves to the next one. This visualisation could be used to recreate a previous object, or to instruct novices. An algorithm could be developed to calculate the actual cuts that need to be made, reducing the amount of planning needed when making an object.

The second visualisation, Target, projects a target model so that it appears to be inside the foam. The foam is coloured based on how much needs to be removed to match a target model. This could be used to create variations on a previous model.

Finally, we can use 3D procedural textures to change the appearance of the foam. For example, we implemented a wood grain 3D texture. This works pretty well, because as you cut away the foam, the texture updates to appear as though the wood was actually cut. 3D textures are also ideal because we don’t need to generate texture coordinates after each cut.
