LPoint3f

class LPoint3f

Bases: LVecBase3f

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.

static TypeHandle get_class_type(void)

LPoint2f get_xy(void) const: Returns a 2-component vector that shares just the first two components of this vector.

LPoint2f get_xz(void) const: Returns a 2-component vector that shares just the first and last components of this vector.

LPoint2f get_yz(void) const: Returns a 2-component vector that shares just the last two components of this vector.

LPoint3f normalized(void) const: 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.

LPoint3f const &origin(CoordinateSystem cs = ::CS_default): 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.

LPoint3f project(LVecBase3f const &onto) const: Returns a new vector representing the projection of this vector onto another one. The resulting vector will be a scalar multiple of onto.

LPoint3f rfu(float right, float fwd, float up, CoordinateSystem cs = ::CS_default): Returns a point described by right, forward, up displacements from the origin, wherever that maps to in the given coordinate system.

LPoint3f const &unit_x(void): Returns a unit X point.

LPoint3f const &unit_y(void): Returns a unit Y point.

LPoint3f const &unit_z(void): Returns a unit Z point.

LPoint3f const &zero(void): Returns a zero-length point.
