💖 QwtPoint3D 💖

okay bestie, so this is the QwtPoint3D(3) page — it's a manpage from the Library Functions Manual, and it's literally all about the QwtPoint3D class 🎀 which defines a 3D point in double coordinates. that's the whole vibe. a point. in 3D. in doubles. slay ✨

🌸 NAME 🌸

QwtPoint3D — the QwtPoint3D class defines a 3D point in double coordinates. periodt 💅

🦋 Detailed Description 🦋

QwtPoint3D class defines a 3D point in double coordinates. that's it, that's the whole personality, and honestly? iconic 👑

Definition at line 22 of file qwt_point_3d.h.

🎀 Constructor & Destructor Documentation 🎀

QwtPoint3D::QwtPoint3D () [inline]

Constructs a null point 🫧

See also: isNull()

Definition at line 65 of file qwt_point_3d.h.

QwtPoint3D::QwtPoint3D (double x, double y, double z = 0.0) [inline]

Constructs a point with coordinates specified by x, y and z.

Definition at line 73 of file qwt_point_3d.h.

QwtPoint3D::QwtPoint3D (const QPointF & other) [inline]

Constructs a point with x and y coordinates from a 2D point, and a z coordinate of 0. lowkey a glow-up from 2D to 3D, we love to see it 💫

Definition at line 84 of file qwt_point_3d.h.

💜 Member Function Documentation 💜

bool QwtPoint3D::isNull () const [inline]

Returns: True if the point is null; otherwise returns false.

A point is considered to be null if x, y and z-coordinates are equal to zero. so like, the origin. the humble little (0, 0, 0) 🍓

Definition at line 97 of file qwt_point_3d.h.

bool QwtPoint3D::operator!= (const QwtPoint3D & other) const [inline]

Returns: True if this rect and other are different; otherwise returns false. (yes, the docs really do say "rect" here — copy-paste moment, we respect the lore 🙈)

Definition at line 171 of file qwt_point_3d.h.

bool QwtPoint3D::operator== (const QwtPoint3D & other) const [inline]

Returns: True, if this point and other are equal; otherwise returns false.

Definition at line 165 of file qwt_point_3d.h.

double & QwtPoint3D::rx () [inline]

Returns: A reference to the x-coordinate of the point.

Definition at line 121 of file qwt_point_3d.h.

double & QwtPoint3D::ry () [inline]

Returns: A reference to the y-coordinate of the point.

Definition at line 127 of file qwt_point_3d.h.

double & QwtPoint3D::rz () [inline]

Returns: A reference to the z-coordinate of the point.

Definition at line 133 of file qwt_point_3d.h.

void QwtPoint3D::setX (double x) [inline]

Sets the x-coordinate of the point to the value specified by x.

Definition at line 139 of file qwt_point_3d.h.

void QwtPoint3D::setY (double y) [inline]

Sets the y-coordinate of the point to the value specified by y.

Definition at line 145 of file qwt_point_3d.h.

void QwtPoint3D::setZ (double y) [inline]

Sets the z-coordinate of the point to the value specified by z. (yep, the parameter is documented as y up top — that's exactly how it is in the source, don't come for me 😭)

Definition at line 151 of file qwt_point_3d.h.

QPointF QwtPoint3D::toPoint () const [inline]

Returns: 2D point, where the z coordinate is dropped. she's downsizing, going back to her 2D roots 💀

Definition at line 159 of file qwt_point_3d.h.

double QwtPoint3D::x () const [inline]

Returns: The x-coordinate of the point.

Definition at line 103 of file qwt_point_3d.h.

double QwtPoint3D::y () const [inline]

Returns: The y-coordinate of the point.

Definition at line 109 of file qwt_point_3d.h.

double QwtPoint3D::z () const [inline]

Returns: The z-coordinate of the point.

Definition at line 115 of file qwt_point_3d.h.
