Vec3 - Documentation

Constructor

new Vec3(x, y, z)

Source:

vec3.js, line 4

Creates new 3D Vector from parameters.

Parameters:

Name	Type	Description
`x`	Number
`y`	Number
`z`	Number

Members

data :Float32Array

Source:

vec3.js, line 17

a float array storing the components of the vector. this can be passed to ShaderProgram as an uniform.

Type:

Float32Array

Methods

copy(other)

Source:

vec3.js, line 126

Parameters:

Name	Type	Description
`other`	Vec3

cross(other)

Source:

vec3.js, line 77

Set this vector to be the cross product with another.

Parameters:

Name	Type	Description
`other`	Vec3

dot(other)

Source:

vec3.js, line 60

Dot product between this and other vector.

Parameters:

Name	Type	Description
`other`	Vec3

isZero()

Source:

vec3.js, line 105

Returns true if all components are zero.

length() → {number}

Source:

vec3.js, line 43

Length of the vector.

Returns:

length

Type: number

lengthSqr() → {number}

Source:

vec3.js, line 36

Squared length of this vector. this is cheaper than Vec3#length.

Returns:

squared length.

Type: number

normalize()

Source:

vec3.js, line 49

Normalizes the vector by dividing it by its own length. This ensures that the length is always one.

transformMat4(mat)

Source:

vec3.js, line 113

Transforms this vector with the given 4x4 matrix.

Parameters:

Name	Type	Description
`mat`	Mat4

(static) cross(a, b)

Source:

vec3.js, line 91

Cross product vector from two vectors.

Parameters:

Name	Type	Description
`a`	Vec3
`b`	Vec3

(static) dot(a, b)

Source:

vec3.js, line 69

Dot product from two vectors.

Parameters:

Name	Type	Description
`a`	Vec3
`b`	Vec3
