RelativeVelocity Method (IAgAccessConstraintPluginObjectData)
See Also

Type: An apparent position indicator.

Frame: Requested frame to express the results

Vx: The X-component of relative velocity in the requested frame, as observed rotating with that frame

Vy: The Y-component of relative velocity in the requested frame, as observed rotating with that frame

Vz: The Z-component of relative velocity in the requested frame, as observed rotating with that frame

Description

The apparent relative velocity of the other object with respect to this object, in the requested frame. Only eUtFrameInertial and eUtFrameFixed are supported.

Parameters

Type

Member	Value	Description
eLightPathApparentPosition	1	Light path apparent position. Accounts for the light time delay (if applied) between objects.
eRefractedApparentPosition	2	Refracted apparent position. Accounts for refraction effects (if applied) on the light path apparent position.
eProperApparentPosition	3	Proper Apparent position. Accounts for aberration effects (depending on the aberration type applied) on the refracted apparent position.

An apparent position indicator.
