question: public float dist ( PVector v ) { float dx = x - v . x ; float dy = y - v . y ; float dz = z - v . z ; return ( float ) Math . sqrt ( dx * dx + dy * dy + dz * dz ) ; }
target:  ( begin auto-generated from PVector_dist.xml ) Calculates the Euclidean distance between two points (considering a point as a vector object). ( end auto-generated )
