If that isn’t enough fun, this post includes some of the code used to generate the picture. If you understand the code, it will give you a big hint for solving the puzzle.

The image was created using the free POV-Ray raytracer. Generating raytraced images involves creating a virtual 3D world with objects and light sources and a camera. POV-Ray then calculates how light travels around the virtual world, bouncing off the objects, and creates the view that would be seen by the camera. The usual aim of raytacing calculations is to mimic real-world physics as much as possible to try to create a photo-realistic image.

A Present of a Picross

Example Picross

A final present from me for Christmas! This time it’s a Picross puzzle.

A picross is a logic puzzle. They’re also called Nonograms, Hanjie, Griddlers or “Paint-By-Numbers”.

The goal is to blacken squares in a grid to create a picture.

Numbers around the grid are clues. From these clues you can deduce exactly where all the black squares go using logic and deduction. There is only one solution where the clues in the columns and the clues in the rows are consistent.

Each clue number signifies an unbroken line of black squares. These lines appear in the same order as the numbers, running left to right for the rows and top to bottom for the columns. Every line of black squares is separated by one or more un-blackened squares. You can mark these in with light Xs. A zero means the entire row or column is unblackened.
