Detailed Description

Representation of a 3D normal vector.

Remarks: This structure is used to describe a normal vector of a polygon. If you get a polygon of a body, you will get an index (ivect field of API_PgonType structure) to an API_VectType structure. Use this index in the head.index field to get the normal vector of that polygon. Note: In the case of closed bodies, they point from the inside to the outside of the body. Normal vectors of an open body must point to the same side of the body.
