Member Function Documentation

◆ normalized()

LPoint4f LPoint4f::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 372 of file lpoint4.h.

◆ project()

LPoint4f LPoint4f::project ( const LVecBase4f 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 384 of file lpoint4.h.

◆ unit_w()

const LPoint4f & LPoint4f::unit_w ( )
inlinestatic

Returns a unit W point.

Definition at line 278 of file lpoint4.h.

◆ unit_x()

const LPoint4f & LPoint4f::unit_x ( )
inlinestatic

Returns a unit X point.

Definition at line 248 of file lpoint4.h.

◆ unit_y()

const LPoint4f & LPoint4f::unit_y ( )
inlinestatic

Returns a unit Y point.

Definition at line 258 of file lpoint4.h.

◆ unit_z()

const LPoint4f & LPoint4f::unit_z ( )
inlinestatic

Returns a unit Z point.

Definition at line 268 of file lpoint4.h.

◆ zero()
