Call of Juarez – Emergent Gameplay based on GPU interactive physical simulation


Wroclaw, Poland May 4th, 2005. 
– developer of
the Wild West themed FPP shooter Call of Juarez – has announced today
that the game will feature an innovative system of interactive smoke and
fluids using Shader Model 3.0. This allows a new level of interaction with the
ever changing dynamic environment that will undergo dynamic changes caused by
various phenomena and the player’s actions. For example the changing wind,
whose breeze can be also affected by the player, moves leaves, hanging
laundry, flags and smoke. A fast ride of a horse moves clouds of dust blown
away by the wind, shots and other horse riders. The game will be shown
publicly for the first time at Techland and NVIDIA stands at E3, 18-20 May in
Los Angeles.


Jakub Klarowicz, the Lead Engine
Programmer at Techland explains:

The inclusion of Shader Model
3.0 technology in NVIDIA’s latest GPU has inspired us to develop incredibly
realistic simulations of fumes, smoke and other phenomena that are yet to be
revealed. Only NVIDIA’s hardware makes this possible and our first
presentation to them during a closed technological presentation of Chrome
Engine 2005 has confirmed that this is indeed a very promising direction.


Daryl Still, Head of Developer
Relations at NVIDIA, stated:

We really liked what was
presented during the presentation of Chrome Engine 2005 at Techland’s
development office. We are very excited about the way the programmers of Call
Juarez plan to use
the Shader Model 3.0 in their product. It will be the proof that introducing
the new technology is another step towards realism in computer graphics.
It is further evidence
that technological
features of graphics cards have more and more influence not only on visuals of
a game but also its gameplay.


The most important aspect for
gamers is undeniably the fact that the application of the features of Shader
Model 3.0 will, according to the developer, strongly affect gameplay. Techland
plans for example, that setting objects on fire, changing their properties
with liquids and other interaction with them as well as smoke and fumes will
become an important part of emergent gameplay which will be characteristic of

the next few days.
