Vector.IntersectionTimes(ThreeDModel, TimeSpanArray, Array) Method

Top

Description

This method provides a sequential listing of events related to the intersection of the calling Vector and intersectingThreeDModel, where one object moves to at least partially intersect another object. The start times and end times of the intersection are returned. FreeFlyer uses a definitive analytical solution to evaluate this method.

Method Signature

Vector.IntersectionTimes(	ThreeDModel intersectingThreeDModel,
	TimeSpanArray EventTime,
	Array EventType)

Arguments

intersectingThreeDModel
Description:	The ThreeDModel used to determine intersection with the calling Vector.

EventTime

Description:

The time that the event occurred.

The FF_Preferences.IntervalEventReportingBehavior property controls whether the start of propagation is reported as an event. By default, if the intersection starts before the beginning of the propagation span, FreeFlyer will label the start of the propagation as the start of the intersection.

EventType
Description:	The type of the event that occurred. Event Type == 1 is beginning of intersection. Event Type == 2 is end of intersection.

Return Value

Type:

number

Returns the number of elements filled into the EventTime, and EventType arrays.

Syntax

myVariable1 = myVector1.IntersectionTimes(myThreeDModel1, myTimeSpanArray1, myArray1);
