Finally, my article doesn't appears in the ShaderX7 book :(
But, hey! I appear inside as contributor. My fifteen minutes of fame :D

Light shafts

In my holidays I'm trying new techniques for my terrain engine. Unfortunately, in my screen space terrain implementations, the well-known artifact of "vertex swimming" appears and it's very noticiable :|

I think that I can reuse the technique in order to code a cool screen space water effect in the near future.

For now, I'd been added the "Game Programming Gems 6" terrain technique (very simple, pretty fast, and without any pre-calculation), light shafts (but the effect needs a radial blur), and particle billboards for cloud rendering.

Goodbye :(

Busyyyyy

Screen space terrain

Lastest days I've been busy coding a demo of a "screen space terrain". There isn't geometry here, only heightmaps. A grid is projected over a plane by a projector camera (in red). At now I'm trying to fix vertex interpolation and making a more better projector. Frame rate is constant because the projected grid has the same size along the scene.
When I finish it, I'll upload a demo with full source code.

How to configure SMC EZ-Connect usb wifi stick into Ubuntu

My current distro is xubuntu 8.10, but it could be apply to
an older xubuntu 8.04, kubuntu, and ubuntu distributions:

1. Install ubuntu
2. Install ndiswrapper from cd instalation folder. Click over this two files:
"/pool/main/n/ndiswrapper-common_1.50-1ubuntu1_all.deb" and
"/pool/main/n/ndiswrapper-utils-1.9_1.50-1ubuntu1_amd64.deb"
3. Copy your ".inf" file from SMC driver CD to a local folder.
4. Type this into console (changing your name and driver name, of course):
ndiswrapper -i /home/user_name/xxxxx.inf
ndiswrapper -mi
5. NOTE: You could be use ndisgtk also, and remember that if your ubuntu
runs at 64bit you need the 64 bit driver (xp64 for example).
6. Type sudo gedit /etc/network/interfaces
7. Copy and paste this into file:
auto lo
iface lo inet loopback

auto wlan0
iface wlan0 inet dhcp
pre-up ifconfig wlan0 up
pre-up iwconfig wlan0 essid WLAN_20
pre-up iwconfig wlan0 key s:'C1131DA6BFB21'

8. NOTE: Change 'WLAN_20' to your wireless name and 'C1131DA6BFB21' to your WEP password.
9. Save file changes and reboot
10. Open firefox and type www.google.com :)

3DisplayForum

This month I've been busy by preparing my conference for the first 3DisplayForum. In the website you'll can download the conferences of the other partners soon.


Hey, that's me :D

My conference was titled "Photo-realistic illumination in real-time" and you can download the PDF of the conference here (sorry, at now only in spanish).

This year was showed in Madrid, I hope that if you live in Spain you can
attend next year if you're interested.
