There are simply too many great things to choose from at Siggraph 2010 and every day is a struggle to narrow it down to only one track at a time.

For instance tomorrow there is a two part course with the title “Advances in Real-Time Rendering in 3D Graphics and games” that covers the entire day. Then there are interesting paper presentations in Boundaries, Edges and Gradients from 9:00-10:30 as well as the Mesh Colors paper in the Textures session and Video tapestries with continuous temporal zoom paper in the Video session both at 10:45-12:15.

There’s also a few interesting talks by NVidia tomorrow which you can find more info on here. It could be interesting to go to the NSight talk 11:00-12:00 to hear a little about what it brings to the GPU programming scene.

At 17:15 there is OpenGL Birds of a feather by Khronos at the Wilshire Grand Hotel you can register here.

Since the paper presentations can be streamed from the ACM digital library after the conference I will probably stick with the course or maybe I will head for a day at the Geek Bar to be able to browse a little of it all.

Look forward to yet another great day at Siggraph

There is a place at siggraph called “The geekbar”. Its sounds like a place to meet and geek out but that is misleading. What you get at this place live audio and video streams of all running tracks are shown. So if you are in doubt of what to attend or want subparts of many tracks this is really the place to go. I have used it quite alot this year and have grown pretty fond of it. Try it out it is super cool.

Capital Globe is a result of our initial exploration of the iphone API. It can be used as a tool to help you learn more about the countries of the world. The capital cities are shown as dots on a globe. By rotating the globe you can shift your focus between different cities and name of the country and capital is displayed along with the flag of the country. A map mode is also available letting you explore each country in more detail. Finally the application lets you browse the Wikipedia entry for each country. Capital Globe is now on the app store.

As part of the Digital Urban Living project we have developed our first iphone app, which is now available in app store:

http://www.digitalurbanliving.dk/projects/civic-communication/klimatrends-iphone-app-english.php

The climate trend app is an innovative and different way to keep up with news, opinions, emotions and environmental sensors before, under and after COP15, the United Nations Climate Change Conference in Copenhagen (December 7-18, 2009).

The app is not simply a newsreader, a social network, a measuring apparatus or a game. It’s a bit of all of that, and more.

* The ocean level indicates the climate situation right now. The worse the situation, the higher the water level. The level is not an exact measure but a reflection of many impressions.
* The ice floes that emerge from below are opinions, articles and readings from CO2 sensors in Copenhagen.
* Tap an ice floe to investigate it further.
* If you are a Twitter user, you can influence the situation, both in the application and through other Twitter applications (by adding #jpcop15 in a tweet).
* You can follow other people and see what they think and how they feel right now about the climate situation.

The primary language in the app is danish. We have implemented both an OpenGL ES1.1 version and a OpenGL ES2.0 version.

Here is small tech demo of our CUDA implementation of the SURF descriptor and matching method for finding a correspondence between images.. Here we are tracking an image of a number plate in a live web cam feed. Notice that the frame rate is bottlenecked by the screen grabbing used to create the video and not the object tracking.
