Member Function Documentation

const scalar_t* math::matrix4::operator[] (  int  i  )  const [inline]

operator [] is used to read, () is to write (const correctness). m[x][y] or m(x)[y] is the correct form.

scalar_t* math::matrix4::operator() (  int  i  )  [inline]

operator [] is used to read, () is to write (const correctness) m[x][y] or m(x)[y] is the correct form.

matrix4& math::matrix4::load_identity (   )  [inline]

Load Identity matrix.

matrix4& math::matrix4::load_rotation (  const scalar_t  angle, const vector4  axis )  [inline]

Load matrix representing rotation about arbitrary vector by arbitrary angle.

matrix4& math::matrix4::load_translation (  const vector4 &  diff  )  [inline]

Load matrix representing translation in 3D space along diff[] vector. Only first 3 elements of diff[] are used.

matrix4& math::matrix4::load_scale (  scalar_t  x, scalar_t  y, scalar_t  z )  [inline]
