Matrix3 class
A class representing a 3x3 matrix.
Constructors
-
Matrix3.fromJson(Map<
String, dynamic> json) - Matrix3.identity()
- Creates a 3x3 matrix with the given arguments in row-major order. If no arguments are provided, the constructor initializes the Matrix3 to the 3x3 identity matrix.

Methods
-
applyMatrix3(
Matrix3 arg) → void -
clone(
) → Matrix3 - Creates a new Matrix3 and with identical elements to this one.
-
copyFromArray(
List< double> array, {int offset = 0}) → Matrix3 -
array- the array to read the elements from. -
determinant(
) → double - Computes and returns the determinant of this matrix.
-
equals(
Matrix3 matrix) → bool -
Return true if this matrix and
page:Matrix3 mare equal. -
factory(
NativeArray< num> array, {int offset = 0}) → Matrix3 -
getNormalMatrix(
Matrix4 matrix4) → Matrix3 -
m- Matrix4 -
identity(
) → Matrix3 - Set the current 3x3 matrix as an identity matrix.
-
invert(
) → Matrix3 - Inverts this matrix, using the analytic method. You can not invert with a determinant of zero. If you attempt this, the method produces a zero matrix instead.
-
multiply(
Matrix3 m) → Matrix3 -
Post-multiplies this matrix by
m. -
multiply2(
Matrix3 a, Matrix3 b) → Matrix3 -
Sets this matrix to
axb. -
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.

-
premultiply(
Matrix3 m) → Matrix3 -
rotate(
double theta) → Matrix3 -
Rotates this matrix by the given
theta(in radians). -
scale(
double s) → Matrix3 -
Multiplies every component of the matrix by the scalar value
s. -
scaleXY(
double sx, double sy) → Matrix3 -
setFrom(
Matrix3 m) → Matrix3 -
Copies the elements of matrix
page:Matrix3 minto this matrix. -
setFromMatrix4(
Matrix4 m) → Matrix3 -
Set this matrix to the upper 3x3 matrix of the Matrix4
m. -
setUvTransform(
double tx, double ty, double sx, double sy, double rotation, double cx, double cy) → Matrix3 -
tx- offset x -
setValues(
double n11, double n12, double n13, double n21, double n22, double n23, double n31, double n32, double n33) → Matrix3 -
toArray(
List< double> array, {int offset = 0}) → List<double> -
array- (optional) array to store the resulting vector in. If not given a new array will be created. -
toJson(
) → Map< String, dynamic> -
toList(
) → List< double> -
toString(
) → String -
A string representation of this object.
inherited
-
translate(
double tx, double ty) → Matrix3 - Translates this matrix by the given scalar values.
-
transpose(
) → Matrix3 - Transposes this matrix in place.
-
transposeIntoArray(
List< double> r) → Matrix3 -
array- array to store the resulting vector in.
Operators
-
operator ==(
Object other) → bool -
The equality operator.
