Rendering Techniques in Call of Juarez: Bound in Blood

I am Pawel Rohleder, 3D graphics programmer and researcher at Techland. Our contribution to GPU Pro discloses rendering techniques applied in Call of Juarez: Bound in Blood, the Wild West FPS action game. The game depicts the wildest West ever through the story of Ray and Thomas McCall, two deadly gunslingers who are in the quest for the legendary gold of Juarez.

The article goes through very detailed description of single game frame rendering process based on deferred shading method. It demonstrates the advanced lighting and shadowing techniques, adopted do complex, open-space virtual environments, combined with top-notch post-processing effects (SSAO, motion-blur, tone mapping) and natural phenomena visualizations (sky, clouds, water, rain).
We also give the reader a short description of various core subsystems (like terrain, geometry, material management) which are the integral tool-kit enclosed in ChromeEngine4.
