Vector3

Vector3

Variables

float pos[3]	naked array containing the values of Vector3
float &x	reference to the first element of pos[]. can be used as myVector3.x.
float &y	reference to the second element of pos[]. can be used as myVector3.y.
float &z	reference to the third element of pos[]. can be used as myVector3.z.

public methods

float Magnitude()	returns non sqr magnitude of current Vector3
float sqrMagnitude()	returns sqr magnitude of current Vector3
void Normalize()	normalizes current Vector3
Vector3 normalized	returns the normalized version of current Vector3

static variables

Vector3 up, down, left, right, forward, back, zero

Variable	x	y	z
Vector3 up	0	1	0
Vector3 down	0	-1	0
Vector3 left	-1	0	0
Vector3 right	1	0	0
Vector3 forward	0	0	1
Vector3 back	0	0	-1
Vector3 zero	0	0	0

use these to quickly obtain a "vector" in a given direction, or a Vector3 filled with 0

static methods

float fastDistance(Vector3 a, Vector3 b)	returns the distance between a and b in a tiled space ( like chess )
float Distance(Vector3 a, Vector3 b)	returns the exact distance between a and b
float Dot(Vector3 a, Vector3 b)	returns the dot product of a and b
Vector3 Cross(Vector3 a, Vector3 b)	returns the cross product of a and b
Vector3 Lerp(Vector3 a, Vector3 b)	returns the middle point between a and b, equivalent to glsl mix(a, b, 0.5) or cg lerp(a, b, 0.5)
Vector3 Lerp(Vector3 a, Vector3 b, float c	returns the point c between a and b, equivalent to glsl mix(a, b, c) or cg lerp(a, b, c)
Vector3 Slerp(Vector3 a, Vector3 b, float c	smooth interpolation between a and b given c.

constructors

Vector3(float x, float y, float z)	generates a Vector3 containing the values x, y and z.
Vector3	generates a Vector3 filled with 0 wihout parameters
Vector3(const Vector3 &vec)	generates a Vector3 from another Vector3.

operators

operator+ adds two Vector3s

operator- substracts two Vector3s

operator+= adds the values of Vector3 to current

operator-= substracts the values of Vector3 from current

operator* multiplies current Vector3 by a float

operator/ divides current Vector3 by a float

operator+ adds float to every value of current Vector3

operator- substracts float from every value of current Vector3

operator*= multiplies every value of current Vector3 by float

operator/= divides every value of current Vector3 by float

operator== returns true if two Vector3s are equal and false if they are different

operator= assigns the values of Vector3 or the x and y values of Vector2 to Vector3
