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

LPoint2f LPoint3f::get_xy ( ) const [inline]

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

Reimplemented from LVecBase3f.

Definition at line 277 of file lpoint3.h.

LPoint2f LPoint3f::get_xz ( ) const [inline]

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

Reimplemented from LVecBase3f.

Definition at line 288 of file lpoint3.h.

LPoint2f LPoint3f::get_yz ( ) const [inline]

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

Reimplemented from LVecBase3f.

Definition at line 299 of file lpoint3.h.

LPoint3f LPoint3f::origin ( CoordinateSystem  cs = CS_default) [inline, static]

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 414 of file lpoint3.h.

Referenced by CollisionPlane::get_collision_origin(), CollisionFloorMesh::get_collision_origin(), CollisionSegment::set_from_lens(), and CollisionRay::set_from_lens().

LPoint3f LPoint3f::project ( const LVecBase3f &  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.

LPoint3f LPoint3f::rfu ( float  right,
float  fwd,
float  up,
CoordinateSystem  cs = CS_default 
) [inline, static]

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

Definition at line 426 of file lpoint3.h.

Referenced by PGItem::activate_region(), and PGEntry::setup().

const LPoint3f & LPoint3f::unit_x ( ) [inline, static]

Returns a unit X point.

Reimplemented from LVecBase3f.

Definition at line 246 of file lpoint3.h.

const LPoint3f & LPoint3f::unit_y ( ) [inline, static]

Returns a unit Y point.
