To avoid hard to understand and not really intuitive C-code, i used gimp to produce the projection images. In this article i'm going to document the code used.

It is used by most absolute incremental encoders and some favor it's use for fringe projection systems that have to encode the pixel data in a series of image patterns (mostly fringes with differing widths). To convert Gray-Code from and to Decimal numbers using c++ i had to look up different approaches with varying difficulty levels. I then compiled the following algorithms, that i will be using for my own fringe projection system (keep tuned).
