Welcome to Blacksmith Studios

Blacksmith Studios is a group of developers focusing on graphics and game developing.
Occassionally, we happen to spend time on other type of applications too. This site is
dedicated to showing off our work to the general public.

We are all amateurs with the passion to create and take development
to higher levels through profound research and dedication.

Finally, I got a blog uploaded, which was the easy part thanks to WordPress. The hard part was to get my equations supported, since LaTeX apparently is not supported by our server host – so thanks to John Forkosh for providing mimetex.

I have just finished my first blog entry, which is about rearranging the classical radiosity equation so the linear system has symmetric and positive definite system matrix. A symmetric positive definite matrix can be Cholesky decomposed, which enables the system to be solved with an arbitrary emission configuration using backsubstitution. This way the radiosity algorithm gets extremely stable numerically and faster than other traditionally matrix solvers. Be sure to check it out it is actually quite neat!

In the time to come I will try and post various thoughts in the subjects of physics, mathematics, and computer graphics regularly, which I hope people will gain some motivation and benefits from.

A Phase of the Moon
29/9 - 2007 by Jakob Gath

Wow, extremely nice year that went past. But it is time to write something! Everybody here at Blacksmith Studios is now working on several different projects - primarily, I would like to announce the project that Soren Dreijer is currently working on - be sure to check it out at www.lanbridger.com. The name really speaks for itself - you can bridge LAN's over the Internet, which makes it possible to, among other things, work remotely and play games such as Dungeon Keeper over the Internet (how awesome is that!).

In the past year, I have played with different techniques in game development to increase lighting realism. I am currently working on an innovative real-time global illumination solution, where every available flop are bled dry both in the multi-core CPU and the GPU! Always have to play with the physical description of light. However, all these small research projects kind of invited the idea of starting a blog where some words about projects, pictures, and maybe small demos could be posted.

Late Summer Fluorescence
31/8 - 2006 by Jakob Gath

A late summer update has arrived (late summer - at least on our side of the planet.)

This time we present an article on how to introduce fluorescence to the radiative transfer equation and how to model it using photon mapping.
This extends the well-known global illumination method to include energy transfer from one wavelength to all others.

The article also presents a new method for evaluating the radiance estimate used in the photon mapping technique, based upon the strength of Fourier series. Enjoy!

The article was originally a final project for the course Appearance Modeling with the instructor Henrik Wann Jensen.

The Bump Mapping Using CG article has been updated and has now reached its 3rd edition.
