as far as i know, depth of field effects are done (or can be done) via Shaders. a Shader is a program that runs on the video cards GPU.
miniB3D does not support shaders by default but user Klepto2 has created an extended version of minib3d that supports GLSL (OpenGL Shader Language)
fish around these forums and you will find some stuff.
