Abstract
A method is presented for calculating a force to apply to components in a computer simulation to simulate the effect that an extinguishing agent stream (e.g., water or foam from a nozzle) should have on airflow in the vicinity of the stream, thereby affecting the movement of other components of the simulation. The method is designed to work in real-time as part of a virtual reality, augmented reality, or other real-time 3-D graphics simulation. In addition to the preferred embodiment of calculating forces to apply to a fire and smoke plume, the invention also contemplates calculation of a force to apply to aerosols and particles that are not part of a fire and smoke plume.
Claims22
A method for producing a real-time computer graphics airflow simulation effect wherein a simulated stream of extinguishing agent from a nozzle affects the path of other simulation components comprising simulation particles emitted from a simulated fire, comprising:
- producing a simulated fire having fire particles emitted from a base that travel along a path for a certain length through the simulation space before disappearing;
- producing a simulated stream of extinguishing agent emitted from a virtual nozzle;
- and
- determining a simulated interaction of the extinguishing agent with the simulated fire particles whereby the particles that come in contact with the extinguishing agent stream have their paths altered, simulating the effects of forced airflow caused by the extinguishing agent stream.
A method for producing a real-time computer graphics airflow simulation effect wherein a simulated stream of extinguishing agent from a nozzle affects the path of other simulation components comprising simulation sub-components emitted from a simulated fire, comprising:
- producing at least one simulation component in the simulation comprising sub-components each moving along a path;
- producing a simulated stream of extinguishing agent emitted from a virtual nozzle;
- determining a simulated interaction of the extinguishing agent with the sub-components, and whereby the sub-components that come in contact with the extinguishing agent stream have their paths altered, simulating the effects of forced airflow caused by the extinguishing agent stream.
