Enum Fixed

Source
pub enum Fixed<N>
where N: Copy + RealField,
{ Hor(N), Ver(N), Upp(N), }
Expand description

Fixed quantity wrt field of view.

  • Implements Default and can be created with Fixed::default() returning Fixed::Ver(N::frac_pi_4()).
  • Implements From<N> and can be created with N::into() returning Fixed::Ver().

Variants§

§

Hor(N)

Fixed horizontal field of view aka Vert- scaling.

§

Ver(N)

Fixed vertical field of view aka Hor+ scaling.

§

Upp(N)

Fixed unit per pixel on focus plane at distance from eye of one aka Pixel-based scaling.
