Vector3 class

Note

A class that represents a 3D vector.

---

class definition

class Vector3 {
     public float x, y, z;

     public void Add(Vector3v)
     public Vector3 Rotate(Quaternion q)
     public Vector3 RotateMatrix(Matrix mat)
}

Example of use

Vector3 vec = new Vector3();
vec.x = 0.0f;
vec.y = 1.0f;
vec.z = 2.0f;

// same as above
Vector3 vec2 = makeVector3(0.0f, 1.0f, 2.0f);

float z

public float z

The z-component of the vector.

Methods

Add(Vector3)

public void Add(Vector3 v)

Adds the vector specified by the argument to the calling vector.

Sub(Vector3 v)

public void Sub(Vector3 v)

Subtracts the vector specified by the argument to the calling vector.

Rotate(Quaternion)

public Vector3 Rotate(Quaternion q)

Rotates the calling vector and returns the result as a new Vector3.

RotateMatrix(Matrix)

public Vector3 RotateMatrix(Matrix mat)

Rotates the calling vector and returns the result as a new Vector3.

Distance(Vector3 v)

public float Distance(Vector3 v)

Returns the distance from vector v.

GetNormalize()

public Vector3 GetNormalize()

Returns a new Vector3 value by normalizing the vector.
