Reference TMatrix2x2

Declared in Codebot.Geometry.pas on line 287

TMatrix2x2 is a two dimensional matrix without translation. Its fields are in rows, so a vector is transformed as (X*A + Y*B, X*C + Y*D).

  TMatrix2x2 = record
  public
    { Create a matrix from its fields }
    class function Create(A, B, C, D: Float): TMatrix2x2; static; inline;
    { Transform a vector }
    class operator Multiply(const M: TMatrix2x2; const V: TVec2): TVec2; inline;
    { Transform a vector }
    function Transform(const V: TVec2): TVec2; inline;
    A: Float;
    B: Float;
    C: Float;
    D: Float;
    V: array[0..3] of Float;
  end;
