Real depth in OpenGL / GLSL

http://olivers.posterous.com/linear-depth-in-glsl-for-real

So, many places will give you clues how to get linear depth from the OpenGL depth buffer, or visualise it, or other things. This, however, is what I believe to be the definitive answer:

This link http://www.songho.ca/opengl/gl_projectionmatrix.html gives a good run-down of the projection matrix, and the link between eye-space Z (z_e below) and normalised device coordinates (NDC) Z (z_n below). From there, we have

A   = -(zFar + zNear) / (zFar - zNear);

B = -2zFarzNear / (zFar - zNear);
