double   sgSpaceMath::ProjectPointToLineAndGetDist(const SG_POINT& lineP, const SG_VECTOR& lineDir, const SG_POINT& pnt, SG_POINT& resPnt)

 

Description:

Finds a projection of the point on the line in the three-dimensional space and returns the distance from the point to the line.

 

 

Arguments:

lineP - point on the line,

lineDir - line direction vector,

pnt - projected point,

resPnt - the result of projecting the pnt point on the line.

 

 

Returned value:

Returns the distance from the point to the line and the projection of the point on the line.
