A training system for training AWACS weapons directors. The training system is programmed so that the student can select between a number of different training modes. These include interactive courseware, simulation, and live exercise modes. The system includes a voice recognition unit that is trained to recognize AWACS terminology and to interactively teach them.

Interactive training system for AWACS weapons directors

A weather effects generator that generates weather data based on real-world weather data, and provides this data to a host simulator. The type of data provided and the spatial distribution of the data depend on the type of simulation. A real world database is accessed to obtain a dataspace of weather data elements, each having a location parameter and various weather-related parameters. For visual display simulators, the data elements are preprocessed to obtain color, transparency, and texture values for each data element. The preprocessed data elements are further processed to obtain a prioritized display list of those data elements that correspond to field-of-view data provided by the simulator. Each data element in this list is assigned a graphics primitive that can be rasterized in accordance with the color and transparency values. Simulators other than visual display simulators provide location data and receive data representing the weather effects at that location.

Weather effects generator for simulation systems

A method of using a computer to provide display data representing a fire. The data is derived from fire model data, so that the fire is realistically displayed with the dynamics of a real fire. Particles are generated from the model data and given location values and other parameters. Each particle becomes a display data element by virtue of being assigned a graphics primitive. The data elements are culled according to a field of view and sorted, so that they may be used for real time display rendering.

Display list generator for fire simulation system

A weather simulation system that generates and distributes weather data to simulation subsystems for the real time simulation of weather conditions, from three-dimensional real world data. A real world database is accessed to obtain a dataspace of weather data elements, each having a set of various weather-related parameters. For 'out-the-window' weather displays, these data elements are preprocessed to obtain color and transparency values for each data element. The preprocessed data elements are further processed to obtain a prioritized display list of those data elements that are in a field of view. Each data element in this list is assigned a graphics primitive, whose alignment is determined by a wind vector of that data element. Pixel values are assigned to the graphics primitives, using color and transparency values of the associated data elements.
