This topic is about the vector3 data type.

vector3 v3 = {23.44,32.3,-13.2};

Previous assignment syntax can be used only during initialization. The following code will raise an error.

vector3 v3;

v3 = {23.44,32.3,-13.2};

After a vector3 is declared, it can be populated either by using the implemented API listed below or by assigning it the values from another vector3.

vector3 v3;

vector3 vv3 = {23.44,32.3,-13.2};

v3 = vv3;

Vector3 type is an array of three double values. It is used for properties such as 3D positions and colors.

Vector3 type supports automatic conversion for

string, if in the correct input format (space separated list of three numbers); otherwise, it will raise an exception:

vector3 v3=”1 2 3”; //v3={1,2,3};

These are the properties for vector3.

Property	Return type	Description
x	double	Used to obtain x value from the vector3.
y	double	Used to obtain y value from the vector3.
z	double	Used to obtain z value from the vector3.

This table shows the currently implemented methods.

Method	Return type	Parameters	Description
Distance	double	vector3 value	Returns the distance between the current point coordinates and value coordinates.
Length	double		Returns the length of the vector3.
Length2	double		Returns the squared length of the vector3.
Lerp		vector3 from, vector3 to, double t	Linearly interpolates between from and to vectors by the interpolant t.
Normalize			Overwrites the vector3 with the normalized vector3.
Slerp		vector3 from, vector3 to, double t	Spherically interpolates between from and to vectors by the interpolant t.
ToString	string		Returns a string that represents the current vector3 value.
