ABSTRACT:
Novel methods for converting coordinates for a position from a first coordinate system into coordinates in a second coordinate system are provided. Linear approximations of trigonometric functions are used to calculate values for the trigonometric functions when a position to be converted is within an acceptable bound of a previous position and more precise values of the trigonometric functions are used to perform the conversion when the position to be converted is not within an acceptable bound of a previous position. The present invention can be advantageously utilized to reduce the computation load in a distributed simulation environment, such as a federation of distributed interactive simulations.
