Displaying lightning strikes

摘要

Lightning strikes are displayed as uniformly-structured (e.g., gaussian) kernels that decay in size and intensity over time. The lightning strikes may be displayed as they occur, or stored for later display. Overlapping areas of the kernels are displayed in different colors than corresponding non-overlapping areas. A color (or colors) displayed in an overlapping area is a function of the number of kernels that overlap in that area.
