Member Function Documentation

◆ normalized()

LPoint4i LPoint4i::normalized ( ) const
inline

Normalizes the vector and returns the normalized vector as a copy.

If the vector was a zero-length vector, a zero length vector will be returned.

Definition at line 1055 of file lpoint4.h.

◆ project()

LPoint4i LPoint4i::project ( const LVecBase4i onto) const
inline

Returns a new vector representing the projection of this vector onto another one.

The resulting vector will be a scalar multiple of onto.

Definition at line 1067 of file lpoint4.h.

◆ unit_w()

const LPoint4i & LPoint4i::unit_w ( )
inlinestatic

Returns a unit W point.

Definition at line 961 of file lpoint4.h.

◆ unit_x()

const LPoint4i & LPoint4i::unit_x ( )
inlinestatic

Returns a unit X point.

Definition at line 931 of file lpoint4.h.

◆ unit_y()

const LPoint4i & LPoint4i::unit_y ( )
inlinestatic

Returns a unit Y point.

Definition at line 941 of file lpoint4.h.

◆ unit_z()

const LPoint4i & LPoint4i::unit_z ( )
inlinestatic

Returns a unit Z point.

Definition at line 951 of file lpoint4.h.

◆ zero()

const LPoint4i & LPoint4i::zero ( )
inlinestatic

Returns a zero-length point.

Definition at line 921 of file lpoint4.h.
