To reflect the ball off of the polyline, we need to re?ect it off of the segment that had the minimum thit. But the reflection computation depends only on thit, n, P and v, so there is actually no need to keep track of which segment was hit. Save thit and n as member variables of the polyline, updating ˆ n in thit at the same time as thit. These will then be the appropriate values when the polyline's reflect is called.
What is scaling and shearing? The scaling transformations alters the shape of an object and can be carried out by multiplying every vertex (x,y) by scaling factor Sx, Sy where
