摘要 |
The invention relates to a reflective surface substantially perpendicular to a vector field described by the equation: W (x,y,z) = T ( proj(x,y,z)) - (x,y,z) + proj(x,y,z) - (x,y,z) ||T(proj(x,y,z)) - (x,y,z)||||proj(x,y,z) - (x,y,z)|| and a method for forming the reflective surface. The reflective surface is capable of providing a non-reversed, substantially undistorted direct reflection. |
