3. DiRT (Dust in Real-Time) is …
Dust in Real-time (DiRT) is a 3D dust visualization program and interactive computer benchmarking tool designed to model real world dust dynamics in a virtual environment in real-time. The interactive benchmarking tool allows users to track and gauge the performance of their system’s ability to render the dust by issuing real-time system and environment related reports. The system reports update in accordance with the users play. Similar to a video game, users will be able to “play” during the simulation by way of a simple vehicle simulator. This paper presents details of DiRT’s UML requirements specification, software architecture specifics, high and low-level design details, user interface principles and snapshots.

4. Practical Applications
Military
The modeling of dust for use in simulations may help modern combat experts plan for or pre-empt the affects of dust caused by vehicles or the atmosphere.
Video Games
Low resource gaming engines.
CAVE Project
Immersive virtual environment.

5. Main Objectives
Simulate/Model Dust
Realistic
Real-time

6. Development Three Methods Volumetric Fog
Diffuse Reflection (future work)
Particle Systems (future work)

7. Method: Volumetric Fog
Large affected area divided into small volumes.
Different Densities
Volumes will translate, morph, etc…
Translation, morphing specified by airflow parameters.
Stencil Buffer and Alpha Blending with multipass rendering creates the illusion.

8. Design: System Architecture

11. Future Work Diffuse Reflection and Particle System methods
Reflection probably most difficult to implement. Less resource intensive than a particle engine.
Particle probably easiest to implement, but very resource intensive.
Implement for CAVE use.
Voxel Processing Method
