Real-time cloth simulation

This project was a part of the course "Animation and Modelling". I choose to implement a cloth simulator using spring-mass system with euler integration. The cloth is made up of the masses connected with three different spring types to simulate the different forces that appears in real cloth (stretching, shearing and bending).

Real-time illumination using HDR images

... is the rather long name on a project I did in the course "Image Based Rendering, Lighting and Modelling". Our project used lightprobes, captured with HDR techniques, to shade an object. We used C# and DirectX and shaders written in HLSL, to calculate the lighting from the environment at each point on the object.

We captured the lightprobes ourself in a 24 hour cycle from the roof of one of the student dorms using the different exposure techniques. The images was then assembled in HDR Shop.

eXtreme Inner City Golf

The purpose of the course "Software Development" is to expose the students to working with software development in larger teams. This is tested practically with a simulated project with fictious customer, in this case students from the programme for "Culture Society and Media production". The development project was to develop a multiplayer game, pc-to-pc via a server, and with characther information stored at the server.

Visits

In the course "Information visualization" each project group was handed a dataset which was to be visualized with methods from the course. In our case the data was tourism statistics from about 40 italian cities near Florens.

We choose to code our project in Macromedia Flash, mostly based on it's graphic capabilities. We attemted to use a technique called "Focus and Context", which means that the user has the ability to scale some regions of the map while keeping a picture of the overall data.

You can download the the report (in Swedish) below.

New images on Flickr

I've had a Flickr account for a almost a year, but basically forgot about it. It seems to have improved greatly since then.

Since I used to have my own server with virtually infinite (well at least I didn't have to worry about it) diskspace I kinda missed being able to put alot of pics on the internet. Today I uploaded my whole month quota of images to Flickr. All of them from the trip to the US me, Josefin and Hanna did in january 2005.

Take a look yourself.

Siggraph 2006, day 5

Realizing that Siggraph is huge you realy have to learn to prioritize. There are simply to many course, papers, sketeches, exibitions and parties to be dealt with. Not to mention to few moments to train for your own presentation.

Tomorrow it's our turn.

Siggraph 2006

So, I'm finally on location in Boston at Siggraph 2006. So far I've been on courses and presentations on subects varying from mrocedural modelling of urban environments to fluid simulation.

It's really crazy here, a lot of people and huge lecture halls. On Thursday I will hold my own presentation (or half of the presentation) in one of those giant halls. Scary...

Long time, no see

Ok, so I know it's a long time since I wrote anything on this page. A lot of things has happened since...let's see, the Siggraph deadline in may! First of all, my sketch was rejected which is a bummer, however the other sketch we sent in, where my supervisor Nafees was the main author and I was listed as the second author, was accepted. This means that I will be going to Siggraph after all. Next week I'll hop on a Icelandic Air flight with Boston as it's destination.

Secondly I have finally graduated from Unviersity with a M.Sc degree. Not a day to late either. The rush was mainly due to fact that I needed to hurry up and get me degree before summer in order to apply for an visa to the US. As it turned out, I was too late and the visa cap for the next fiscal year (starts in October 2006) had already been reached. Thus no work in the US for me...

Siggraph deadline passed!

Phew, I'm all exhausted. The Siggraph deadline passed an hour ago, and we survived. We actually submitted two sketches in the end, one of which I'm listed as the main author. It seems that this will be yet another record year with up to 700 sketches. I think about 100 get accepted, so there is a slim chance that we'll get accepted.

Now I'm ready to take a nap...

Siggraph deadline approaches

The Siggraph 2006 sketch deadline approaches relentlessly which means that we need to accelerate our work at DD. I'm going in to work tomorrow to put the finishing touches on our renderer. The volumes are begining to look really cool, and hopefully we'll finish on time.
