In this post we will see how to create a simple JSON server in Python to mock external APIs. This can be useful when developing an application that will make use of third-party applications via the provided APIs since it provides a controlled development environment. It gives you control over the data that is received,…More
Automating Weather Widget Generation
This entry is a fun little project I have been working on for the last week. It is nothing special or groundbreaking, but I hope you have some fun reading it. One of the features we wanted to add to MadBoulder’s website (short description of the project at the end) was, for each page refering…More
Procedural Racetrack Generation
This post explains my personal take (in Python) of the work done by Gustavo Maciel and explained in this article. Introduction I have been thinking for some time to develop a game that mimics the mechanics of vector racer (nothing new here). When I finally started to work on it, I thought it would also be a…More
Lane detection via Hough Transform
This work was developed in conjunction with Carlos Trapiello During my Master’s degree I was lucky enough to work on several projects which turned out to be both interesting and fun. One of these projects was to develop a simple road lane detector via the Hough transform. When I first read about the Hough transform…More
Augmented Reality with Python and OpenCV (part 2)
The code of this project can be found here. For those of you that have found this post before part 1 or that want to refresh what we have done up to this point, here you can catch up with the current state of the project so far. For the rest, we’ll keep going from where…More
Augmented reality with Python and OpenCV (part 1)
You may (or may not) have heard of or seen the augmented reality Invizimals video game or the Topps 3D baseball cards. The main idea is to render in the screen of a tablet, PC or smartphone a 3D model of a specific figure on top of a card according to the position and orientation of…More
Converting images to ASCII art (Part 2)
Today’s post is the second and last on how to convert images to ASCII art (in case you missed it and want to quickly catch up, here’s part 1). We already have a grayscale version of the image we want to convert and we have also developed a method that allows the user to adjust…More
Converting images to ASCII art (Part 1)
In the last post we discussed a simple method for procedurally generating 2D terrain. In today’s post, we will also generate an image that will be the final output of our program, but with a totally different purpose and method. Today we will try to generate ASCII art from images. For those of you who…More
Landscape generation using midpoint displacement
Today I will present how to implement in Python a simple yet effective algorithm for proceduraly generating 2D landscapes. It is called Midpoint Displacement (or Diamond-square algorithm, which seems less intuitive to me) and, with some tweaking it can also be used for creating rivers, lighting strikes or (fake) graphs. The final output may look like the…More
