Detailed Description

template<typename State>
struct Aleph::CA::Binary_Gray_Mapper< State >

Default binary grayscale mapper.

Cells equal to dead become dead_value; all other states become alive_value. This matches the usual Life visual convention: live cells are black, dead cells are white.

Template Parameters

State

cell state type.
