Parameters

rayStart

Type: OIV.InventorSbVec3f

rayDirection

Type: OIV.InventorSbVec3f

nearDistance

Type: SystemSingle

farDistance

Type: SystemSingle

The ray is defined as a world space starting point and direction vector. The direction vector will be normalized automatically. The last two arguments specify optional near and far plane clipping during the pick operation. These values are distances from the start point along the direction vector, similar to nearDistance and farDistance in SoCamera. A negative distance (such as the default values) means disable clipping to that plane.

NOTE: You can use this method or the setPoint / setNormalizedPoint methods. Whichever method you call last is the one that takes effect.
