Class SegmentQueryInfo

Definition

Namespace:
Tizen.NUI.Physics2D.Chipmunk
Assembly:
Tizen.NUI.Physics2D.dll

Segment queries return where a shape was hit and its surface normal at the point of contact. Use Shape == null to test if a shape was hit. Segment queries are like ray casting, but because not all spatial indexes allow processing infinitely long ray queries, it's 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.
