Bullfrog After Populous

I’ll give you an analogy of what Populous is in my mind. Imagine if I had a blank canvas. Some people that are true artists will take a palette of paint and mix them together and carefully handcraft each and every single brushstroke until they have some beautiful and amazing picture. And then there’s me. I had the…

Deep Learning for Guitar Effect Emulation

Since the 1940s, electric guitarists, keyboardists, and other instrumentalists have been using effects pedals, devices that modify the sound of the original audio source. Typical effects include distortion, compression, chorus, reverb, and delay. Early effects pedals consisted of basic analog circuits, often along…

Simplifying Board Games

A few years ago I wrote about how I'd been playing a simplified version of Carcassonne with Lily. We stopped for a while, but recently we've played simplified versions of Ticket to Ride, Race for the Galaxy, Guillotine, and Settlers of Catan. My general approach here is to find a core piece of the game that will be…

Krita, OpenGL and Qt

Adrian Page first coded an OpenGL-based canvas implementation for Krita in 2005 . That was back in the Qt3 days. OpenGL was fairly simple back then, but we had to duplicate all our canvas handling code, once implemented in OpenGL, once implemented with QPainter.

Fast 2D Rendering on GPU

Previously on my quest for fast rendering of 2D vector graphics on GPU, I have posted a piet-gpu update and a deeper exploration into a sort-middle architecture. These intermediate results showed promise, but fell short of my vision for truly high performance 2D GPU rendering.

Game Programming Patterns: Event Queue (2014)

Unless you live under one of the few rocks that still lack Internet access, you’ve probably already heard of an “event queue” . If not, maybe “message queue”, or “event loop”, or “message pump” rings a bell. To refresh your memory, let’s walk through a couple of common manifestations of the pattern.

Master of Orion

Given the shadow which the original Master of Orion still casts over the gaming landscape of today, one might be forgiven for assuming, as many younger gamers doubtless do, that it was the very first conquer-the-galaxy grand-strategy game ever made. The reality, however, is quite different. For all that its position…

The Polygons of Doom: PSX

It was a pleasure to research the material for the "Polygons of Another World" articles [1] . All the machines I studied were different from one another. The diversity I witnessed in the Amiga, Atari ST, PC, SNES, Genesis, GBA, and Jaguar demonstrated the richness of a field then still in its dawn. As I concluded the…

Parallel Seam Carving

Seam carving is a technique for content-aware resizing, which changes the size of an image while attempting to preserve the interesting content of the image. The basic idea behind the technique is to remove low-energy seams: paths of pixels that are similar to their surroundings. A removed seam can be either vertical…
