CP::SegmentQueryInfo

Segment queries return more information than just a simple yes or no, they also return where a shape was hit and its surface normal at the hit point. This object holds that information.

Segment queries are like ray casting, but because not all spatial indexes allow processing infinitely long ray queries it is limited to segments. In practice this is still very fast and you don't need to worry too much about the performance as long as you aren't using extremely long segments for your queries.
