Procedural City is a demo that uses a few tricks to build random nice-looking 3D cities.

First, neighborhood blocks are randomly placed in an irregular rectangle grid.

Then, building allotments are packed inside blocks using this bin packing algorithm.
Bin packing uses an heuristic that tries to maximize edge contact for "bins". This leads to better fitting of allotments along block edges.
Once blocks are filled, non-edge allotments are discarded.

Buildings are extruded from allotments and their façades decorated by two pattern matrices.
Matrices are picked from one of six achitectural styles (art deco, art noveau, brownstone, chicago old school, international and modernist).
One pattern matrix implements simple block extrusion/exclusion to be performed in the façade geometry.
Another determines which element (ie.: window, door, column) should be appended where in the façade.
Details (ie: headers, rails, firestairs) are randomly selected according to the defined achitectural style.
Finally, some common props (ie: chimney, water tank) are scattered around the rooftops.

Built with Unity personal edition.

Wire3d is a multiplatform game engine created by antibyte. Written in C++, fully open source and licensed as LGPL.

In early 2012, I started contributing to the project, developing the code for reading controllers, improving bullet physics integration, etc. At the sime time we started a 3rd person shooter demo.

At the end of the year, we decided to do some unit testing and so we started using googletest and google mock, testing and mocking platform specific code and running them on their own platforms (real or emulated).

Cubescape is an action-platformer with some puzzle ingredients. It stopped being developed in 2013. This unfinished version features 3 levels and 1 boss stage. It was built with C# and Unity personal edition.

While playing Cubescape, you impersonate Lucia, a bright-skinned robot girl that has an elastic band as hair. The game starts as Lucia wakes up imprisioned in a weird place made out of cubes. She then learns she can move some of those cubes with her telekinetic powers and break free from her prision.

Cubescape requires a combination of thinking and manual skills, asking the player to disable traps with Lucia's telekinectic powers while jumping and moving through the scenarios.
