Use to add or remove time-distance values to the target projection of a targeted sensor. The target projection is based on the current animation time and the time-distance values. Each distance value is used when the animation time is equal to or after the associated time for that distance until another time-distance pair becomes valid. If no time-distance pair is valid (that is, the animation time occurs before the first time-distance pair), the value set for the constant target projection is used.
To vary the sensor target projection over time, select Time Varying and click Edit Intervals... on the 3D Graphics Projection properties page for a sensor.
To set the Pointing type to Targeted for a sensor, select Targeted on the Sensor's Basic Pointing properties page.
