operator*() [1/3]

Vector3D SRL::Math::Types::Matrix33::operator* ( const Vector3D & v ) const

inlineconstexprinherited

Transform a vector by this matrix.

Applies the transformation represented by this matrix to a vector through matrix-vector multiplication. This is commonly used to:

• Transform a point in local space to world space
• Apply a rotation to a direction vector
• Scale a vector

Parameters

v	The vector to transform.

Returns

The transformed vector.

Note

For a rotation matrix, the length of the input vector is preserved.

Vector3D direction(0, 0, 1);
Matrix33 rotation = Matrix33::CreateRotationY(Angle::FromDegrees(90));
Vector3D rotated = rotation * direction; // Rotates the vector 90° around Y axis
