Welcome!

My name is Kristian Lindstrom and I would probably be best described as a jack of all trades in the field of programming. My main field is in games where I have my degree and programming and games are my biggest interests. I also worked with web and had the opportunity to work with some interesting projects.

Mostly I have worked in back-end systems and it is how I prefer it technology software engineering and back-end solutions. Although I also like working in front-ends.

Socially I like to spend time on my own projects spend time with my girlfriend or have a cup of coffee with friends. Where there still is time I love spending it playing games.

I hope that you want to check out the other parts of the site to see what I have done and more about my interests and professional life. And if you are in a hurry or just prefer a more traditional reading please grab a copy of my CV either in pdf or in doc format.

I developed a back-end and front-end solution for a company in Stockholm where the wishes were to provide a highly customizable site. The company wanted to be able to update much information and content and I built the whole back-end and front-end without any CMS1 mainly because I wanted to use the opportunity to learn more about ajax mysql and php.

Smooth silhouette rendering of low polygon models for computer games

Abstract
This dissertation presents a method capable of smoothing the silhouette of a 3D model using interpolation to find smooth edges. The method has as goal to be used with normal mapping to improve the performance and give a better result with a low polygonal count. To do this the lines located on the silhouette of a model is interpolated to find a curve that is used as clipping frame in the stencil buffer. This method is able to modify the silhouette for the better. The amount of interpolation is rather limited.

Keywords: Tangent spaces normal map interpolation stencil buffer rendering Cubic Hermite Interpolation silhouette edge detection.

Game physics

This was one of my most favorite classes I took at Skovde. Computer games physics at advanced level. The project is not all that impressive however I had to put a lot of work into it. Sad to say the version you can try here is in fact not the final version which got lost in a hard drive which was destroyed in Brazil.

This project utilize a couple of parameters such as weight of the players a spring force representing the legs torque and Inertia. The final version also had power-ups which were used to gain strength in different parameters. The power-ups themselves had weight as well and that way had a great impact on the game-play.

Purpose:
project in game physics.
Language:
Applet written in Java
Platform:

World kopp

I actually have done a couple of these kind of scripts. The first one I did to take a character which some people at school did for a class in animation. That first script was very clumsy and used a lot of space because it actually did save every animation key-frame as a separate model. This script were then parsed into a C program I wrote and then it became somewhat a viewer for 3D models and could handle key-frame animation. but needless to say these files were quite big. For my dissertation I made a new script which handled static models and finally I made a new version which exported in XML. The last version of this exporter handled all geometry at one stage and then bones or skeleton in another step.

Modelviewer

I made this project on my spare-time at school. Parallel with some friends which made the model in a class in animation techniques. The model-viewer tool was a big challenge and it did create key-frames for each pose of the animation (i.e. no skeleton animation). for the model exporter I wrote a MEL-script (see above).

Minimum enclosing bounding rectangle

Purpose:
Class in computational geometry
Language:
Java
Platform:

I made this one for a class in Computational Geometry at the university. The way it work is that it compute the convex hull and use this information to find the minimum rectangle which enclose the whole set of vertices.

Pervasive presentation scheduling using

Purpose:
Class in pervasive computing
Language:

Platform:
Java server
Nokia 6131 NFC

A project where we wrote a java-server which started on command from a NFC tag. When the program starts a presentation is sent to the server and depending on input from the cell-phone you can steer the presentation.

In simple this mod adds a bar used in your interface to show how much threat you have compared to the tank. A counterweight value is calculated and it is meant to help you know when you are a bit too high on threat and need to ease of some in order not to steel the tanks aggro.

It is mainly for DPS classes but can by all means be used by anyone that like having a bit of extra knowledge about their threat.

A pretty full featured breakout clone made in the World of Warcraft interface. It is kind of a game to play while waiting for other things to happen. The clone has a level editor for players to create and save their own levels over sessions.

A star implementation

Qrikkos arcade system

Language: Lua / XML

A implementation of the A-star algorithm. I made this project as a work-sample. I made one version in C and one in Java.

The site you are now looking at. It is a bit more then what you would see at a glance. Underneath there actually are both a light-weight tool-set in javascript and further more it is a very open sandbox kind of editor which I first developed as a means of providing a flexible solution for what I call simple webpages. With simple I mean sites which does not have web-shops communities and so on but rather just present information.

Another pure work-sample implementation. I did this project over a week to provide with an application for a J2ME employment. The application have basic mini-max AI and a two player mode.

Work sample

I made this project mainly just as a work sample. It was made in three parts where modeling and animation was one step (please observe however I am no artist and the quality of the modeling and animation is really not something I hold for a strong trait of mine).
The second part was tools or scripting. In this phase I wrote a MEL-exporter script to be able to work with the model externally.
Final step was implementation in OpenGL and C where I wrote classes to load and handle the model. Orientations are done with quaternions for animation joints.

I will refer to the documentation for further details.

What is this?

Under hobby projects you will find both school work and hobby projects. It is a gathering for all my non-professional work.

School projects are everything done in school in different forms. Can be assignments and where I still have code and material it is provided as downloads.

Spare-time Projects can be anything from a game-mod to a shell script and anything in between. They are arranged mainly after their relevance as a date might be hard to decide. Where applicable there can be video and images or code downloads.

Technology and Gameplay programming

Worked on a game-project with all programming for Airplay with their own IP. In this project I have been responsible for writing all code from rendering sound and input to gameplay.

This have been a real challenge and I have had the chance to grow as a developer with a lot of responsibility. We are currently in the test-phase where I am fixing bugs and the release is closing in.
