Комментарии

Структура Vector2 обеспечивает поддержку аппаратного ускорения.The Vector2 structure provides support for hardware acceleration.

В матричных преобразованиях экземпляры Vector2, Vector3 и Vector4 отображаются в виде строк: вектор v преобразуется матрицей M с помощью умножения vM.For matrix transformations, the Vector2, Vector3, and Vector4 instances are represented as rows: a vector v is transformed by a matrix M with vM multiplication.
