[name]
A 3x3 matrix.
Constructor
[name]([page:Float n11], [page:Float n12], [page:Float n13], [page:Float n21], [page:Float n22], [page:Float n23], [page:Float n31], [page:Float n32], [page:Float n33])
n11 -- [page:Float]
n12 -- [page:Float]
n13 -- [page:Float]
n21 -- [page:Float]
n22 -- [page:Float]
n23 -- [page:Float]
n31 -- [page:Float]
n32 -- [page:Float]
n33 -- [page:Float]
Initialize the 3x3 matrix with a row-major sequence of values.
n11, n12, n13,
n21, n22, n23,
n31, n32, n33
If no values are sent the matrix will be initialized as an identity matrix.
Properties
[property:Float32Array elements]
Float32Array with column-major matrix values.
Methods
[method:Matrix3 transpose]()
Transposes this matrix in place.
[method:Matrix3 transposeIntoArray]( [page:Array array] )
array -- [page:Array]
Transposes this matrix into the supplied array, and returns itself.
[method:Float determinant]()
Returns the matrix's determinant.
[method:Matrix3 set]([page:Float n11], [page:Float n12], [page:Float n13], [page:Float n21], [page:Float n22], [page:Float n23], [page:Float n31], [page:Float n32], [page:Float n33]) [page:Matrix3 this]
n11 -- [page:Float]
n12 -- [page:Float]
n13 -- [page:Float]
n21 -- [page:Float]
n22 -- [page:Float]
n23 -- [page:Float]
n31 -- [page:Float]
n32 -- [page:Float]
n33 -- [page:Float]
Set the 3x3 matrix values to the given row-major sequence of values.
[method:Matrix3 multiplyScalar]([page:Float scalar]) [page:Matrix3 this]
scalar -- [page:Float]
Multiply every component of the matrix by a scalar value.
[method:Array applyToVector3Array]([page:Array array])
array -- An array in the form [vector1x, vector1y, vector1z, vector2x, vector2y, vector2z, ...]
Multiply (apply) this matrix to every vector3 in the array.
[method:Matrix3 getNormalMatrix]([page:Matrix4 matrix4]) [page:Matrix3 this]
matrix4 -- [page:Matrix4]
Set this matrix as the normal matrix of the passed [page:Matrix4 matrix4]. The normal matrix is the inverse transpose of the matrix.
[method:Matrix3 getInverse]([page:Matrix4 matrix4], [page:Boolean throwOnInvertible]) [page:Matrix3 this]
matrix4 -- [page:Matrix4]
throwOnInvertible -- [Page:Boolean] If true, throw an error if the matrix is invertible.
Set this matrix to the inverse of the passed matrix.
[method:Matrix3 copy]([page:Matrix3 matrix]) [page:Matrix3 this]
matrix -- [page:Matrix3]
Copy the values of the passed matrix.
[method:Matrix3 clone]()
Create a copy of the matrix.
[method:Matrix3 identity]() [page:Matrix3 this]
Set as an identity matrix.
