Detailed Description

Represents a point in 3D space.

The Point class is a simple wrapper around a 3D vector to represent a point in space. It provides constructors for initialization and access to the underlying vector components.

Constructor & Destructor Documentation

Point() [1/2]

Point::Point ( float  x, float  y  )

inline

Constructor from 2D coordinates.

Initializes the point with the specified x and y coordinates, z defaults to 0.

Parameters

x	The x-coordinate of the point
y	The y-coordinate of the point

Point() [2/2]

Point::Point ( float  x, float  y, float  z  )

inline

Constructor from coordinates.

Initializes the point with the specified x, y, and z coordinates.

Parameters

x	The x-coordinate of the point
y	The y-coordinate of the point
z	The z-coordinate of the point
