Assorted bits and pieces

DominoSolver

This is a small program which generates a Dominosa problem to solve, then uses my implementation of Knuth's Algorithm X to solve it. The controls are:

Press 'r' to generate a new puzzle
Press 'p' to pause the solution search
Press 's' to single step the solution search
Press 'c' to continue the solution search

Eternity2

This started out as a utility to help explore the huge Eternity2 puzzle, but as usually happens with me, I became sidetracked by pretty objects. The puzzle solving aspect is a minor part of this tool - the major focus of it is in procedurally generating the designs of the tiles, and from a programming point of view getting practice using the OpenGL stencil buffer by using it to produce different designs, and learning how to render to many textures.

To edit a design, pan over to the single tile view (its near the bottom right of the board), and press the spacebar. (To pan, drag with the right mouse button.) Labels will appear underneath some of the sliders, indicating they may be changed to alter the design. This is the area in question:

If you pan to the left, you'll see this design repeated on a grid, to give you an indication of how it looks when tesselated. You can continue editing here as well of course.

If you like, you can still "play" Eternity 2, and attempt to solve the puzzle - when you click on an empty part of the board (the large greyish area), candidate pieces are revealed on the top right, which you can click to place the tile. Tiles highlighted green have already been placed, and will be moved if you click them. I was going to investigate some simple auto placement strategies, but I got bored and moved on before I did this.

Included is a file called e2dataset.txt. This is not the official Eternity 2 tile set - it is a randomly generated tile set which includes border and corner pieces.

PegSolitaire

A simple implementation of Peg Solitaire. Right click to move a peg. There is some inactive AI code in the project.

RenderToTexturePlay

A simple render to texture experiment. Not interactive, but the texture is animated, so it may have instructive value.

FreewaySim

A simple simulation to play with some of the dynamics of traffic and overtaking behaviours.

Some of the parameters are in the Freeway constructor if you want to play around.

EmptyWorld

Its an empty world. Its a simple 3D environment complete with scene picking and an intuitive camera behaviour which you can use to render whatever thing you're working with in a 3D space instead of the usual console window.
