摘要： A method of using a computer to provide display data representing a fire. The data is derived from a fire model process (11), so that the fire is realistically displayed with the dynamics of a real fire (15). Particles are generated from fire model data (11a) generated by the fire model (11). Each particle is given a three-dimensional location and other parameters (105), as determined by the fire model data (11a). Each particle becomes a display data element by virtue of being assigned a graphics primitive, see Figure 3. The data elements are culled according to a field of view and sorted, see Figure 4, so that they may be used for real time display rendering.

摘要： A weather effects generator (10) that generates weather data based on real-world weather data, and provides this data to a host simulator (16). The type of data provided and the spatial distribution of the data depend on the type of simulation. A real world database (11) 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.

摘要： 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 (11) 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 (14) 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.
