Electricity flow material

I have added a new article on my website about a simple material featuring electricity flowing down a printed circuit. Everything is here with the traditional executable and source code!

Basically, instead of this:

You get that:

Feel free to improve it and to discuss about it here! :)

PhD 3D Engine - Conclusion

I have finally written an article on my website about the engine I have developed for My PhD thesis. This engine made my life easier as a PhD student.

I have learned a lot during its development:

• first shadow mapping, virtual indirection cubemap
• first scripting integration
• first record/replay

I was then able to quickly:

• design my experiments using scripting
• build environments under Maya+MentalRay
  
• record user's actions in the VE
• extract meaningful data for analysis
  

And finally, I was able to put nice screenshots in my papers and became a doctor! :)

OpenCL Slisesix

The SliseSix OpenCL demo is finally out! :)
Feel free to discuss it here.

OpenCL demo of Iniguo Quilez slisesix - SOON

I will soon release an OpenCL implementation of Iniguo quilez's slisesix demo . In this demo, you will be able to "interactively" move the camera in the scene.

I am also currently working on a high-quality/resolution version. It will generate a single screen-shot with depth-of-field and more visual effects impossible to do for a real-time exploration of the scene on my poor nVidia GeforceGTX275.

The demo will also feature a preview version of nVidia Timothy Lotte's SSAA algo called FXAA3 (preview version). He sent me a preview version for testing purposes and was kind enough to accept me including a preview version in the upcoming download-able demo. By the way, there will be a Siggraph course this year on SSAA.

Here are two screenshots:

The demo from shadertoy with fxaa3,volumetric fog and camera control.

New website online - Still no 3D stuff... :-/

My new website is now up at the following address: http://sebastien.hillaire.free.fr/. I took my whole Sunday to finalize it (even though the project section is still missing). The website has been designed using Joomla: I recommend you to use it if you want a clean website.

I will now be able to finish the last article of my PhD requiring a revision. Then I will go back to 3D experiments in-between two sessions of Starcraft2. ;)

More updates coming soon

I know that I have not updated my blog for a while and this is due to many factors: many recent deadlines at work (crunch time ftw), re-design of my personal website (it turns out that it takes a lot of my free time, it should be finished soon), etc. I have also spent a lot of time updating my knowledge of ASM (never used during my PhD!) and experimenting with a particular focus on low level optimizations using MMX and SSE. Applications of this at work were really successful! :)

I will refocus soon on 3D experiments and, hopefully, I will be able to show you something about my work at Dynamixyz.

Stay tuned! :D
