float a, b, c, d
HT_Plane
Purpose
HT_Plane ()
HT_Plane (HT_Vector const & vec, float distance)
HT_Plane (HT_Vector const & vec, HT_Point const & point)
The second initializes the plane to (vec.x, vec.y, vec.z, distance).
The third form is similar to the second form, however it depicts the distance based on the point (vec.x, vec.y, vec.z, point).
Purpose
float a,b,c,d
