The PlayCanvas Engine is a JavaScript library engineered specifically for building video games. It implements all of the major components that you need to write high quality games: Graphics: model loading, per-pixel lighting, shadow mapping, post effects Physics: rigid body simulation, ray casting, joints, trigger volumes, vehicles Animation: keyframing, skeletal blending, skinning Audio engine: 2D …

There are lots of clever one-liners for generating random colors: ‘#’+Math.floor(Math.random()*16777215).toString(16); Unfortunately, this code naturally produces lots of greys and browns and murky greens. randomColor generates attractive colors by default. More specifically, randomColor produces bright colors with a reasonably high saturation. This makes randomColor particularly useful for data visualizations and generative art. The result pictured …

See the Pen Pure CSS 3D animated icosidodecahedron (pentagonal gyrobirotunda) by Ana Tudor (@thebabydino) on CodePen. You might think that math doesn’t have a lot to do with writing stylesheets, but you can actually do some amazing things with a little math in CSS. Math (particularly trigonometry) can help you model the real world. You’ll …

Layouts where content hugs the boundaries of illustrations are common in print and rare on the web. One of the reasons non-rectangular contour-hugging layouts are uncommon on the web is that they are difficult to produce. They are not difficult to produce anymore. And once again I have a flashback to (the now offline) The …
I recently visited a parallax scrolling website that was just one of thousands of different parallax scrolling websites out there. One thing that I immediately noticed was that the scrolling FPS of that page was really bad. I suspected that there would be room for improvement in their parallax implementation, and I wanted to take …
