Detailed Description

This is a three-component point in space (as opposed to a three-component vector, which represents a direction and a distance).

Some of the methods are slightly different between LPoint3 and LVector3; in particular, subtraction of two points yields a vector, while addition of a vector and a point yields a point.

Member Function Documentation

◆ get_xy()

LPoint2i LPoint3i::get_xy ( ) const
inline

Returns a 2-component vector that shares just the first two components of this vector.

Definition at line 1141 of file lpoint3.h.

◆ get_xz()

LPoint2i LPoint3i::get_xz ( ) const
inline

Returns a 2-component vector that shares just the first and last components of this vector.

Definition at line 1152 of file lpoint3.h.

◆ get_yz()

LPoint2i LPoint3i::get_yz ( ) const
inline

Returns a 2-component vector that shares just the last two components of this vector.

Definition at line 1163 of file lpoint3.h.

◆ normalized()

LPoint3i LPoint3i::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 1246 of file lpoint3.h.

◆ origin()

const LPoint3i & LPoint3i::origin ( CoordinateSystem  cs = CS_default)
inlinestatic

Returns the origin of the indicated coordinate system.

This is always 0, 0, 0 with all of our existing coordinate systems; it's hard to imagine it ever being different.

Definition at line 1292 of file lpoint3.h.

◆ project()

LPoint3i LPoint3i::project ( const LVecBase3i 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 1258 of file lpoint3.h.

◆ rfu()

LPoint3i LPoint3i::rfu ( int  right,
int  fwd,
int  up,
CoordinateSystem  cs = CS_default 
)
inlinestatic

Returns a point described by right, forward, up displacements from the origin, wherever that maps to in the given coordinate system.

Definition at line 1304 of file lpoint3.h.

◆ unit_x()

const LPoint3i & LPoint3i::unit_x ( )
inlinestatic

Returns a unit X point.

Definition at line 1110 of file lpoint3.h.

◆ unit_y()

const LPoint3i & LPoint3i::unit_y ( )
inlinestatic

Returns a unit Y point.

Definition at line 1120 of file lpoint3.h.

◆ unit_z()

const LPoint3i & LPoint3i::unit_z ( )
inlinestatic

Returns a unit Z point.

Definition at line 1130 of file lpoint3.h.

◆ zero()

const LPoint3i & LPoint3i::zero ( )
inlinestatic

Returns a zero-length point.
