double Length

(

const DPoint3 &

v

)

[inline]

Remarks:

Returns the 'Length' of the point. This is sqrt(v.x*v.x+v.y*v.y+v.z*v.z)

Definition at line 116 of file dpoint3.h.

                                       {    
    return (double)sqrt(v.x*v.x+v.y*v.y+v.z*v.z);
    }

GEOMEXPORT int MaxComponent

(

const DPoint3 &

)

Search for all occurrences

Remarks:

Returns the component with the maximum absolute value. 0=x, 1=y, 2=z.

GEOMEXPORT int MinComponent

(

const DPoint3 &

)

Search for all occurrences

Remarks:

Returns the component with the minimum absolute value. 0=x, 1=y, 2=z.

GEOMEXPORT DPoint3 Normalize

const DPoint3 &

)

Search for all occurrences

Remarks:

Returns a unit vector. This is a DPoint3 with each component divided by the point Length().
