All posts and recent updates

This blog aim to provide articles related to graphics in game. Their purposes are to be use as references by myself and any other people interested. To facilitate the navigation in this blog I will use this site map page.

Unlike traditional blog I would like to keep the articles up to date when this have interest. Thus every post have a version number. When I add an information to an article I increment the version and add a comment at its end with some details on what have changes. As WordPress don’t allow me to set up the link of my post and so break reference to the post when I update them, I will use this posts to provide information of last articles update.

Last update articles:

Slides of Sébastien Lagarde (Me) and Antoine Zanuttini conferences at Siggraph 2012 and Game Connection 2012 about a method to include fast reflection everywhere on your scene with good enough quality for PS3/XBOX360 platforms:

Siggraph 2012 and Game Connection 2012 talk : Local Image-based Lighting With Parallax-corrected Cubemap

I write a complete article on the topic of the above conferences with more details and code:

Image-based Lighting approaches and parallax-corrected cubemap : v1.28

Me and Antoine Zanuttini describe an extention for this method with image proxies in a GPU Pro 4 article:

GPU Pro 4 – Practical planar reflections using cubemaps and image proxies (with video)

FXGuide Game environment series on the rendering of Remember Me:
