Web experiment: Drone physics

For a long time I wanted to try some 3D physics on the web. For that purpose there are two libraries around, Cannon.js which is written in JS from scratch, and Ammo.js which is a port of Bullet made using emscripten. I’ve been playing around with both of them, the performance of cannon could be improved (too much garbage generated in memory) and the interface of ammo is horrible (as all emscripten ports).

Play around with this demo, the controls are very hard and it is easy to start spinning uncontrollably, but Im pleased with the movement.

This year for the Music Hack Day I wanted to do some visualization using WebGL. Some of my friends were doing a hack using a Maschine from Native Instruments so I decided to get the Midi messages (using the Web MIDI API) and visualize them somehow. This is the video of the presentation.

You can try the visualization here but without a MIDI keyboard sending events is quite boring.

Conway Stamps Collection

The other day I wanted to clean a little bit the code of my Conway Game of Life GPU web app, and meanwhile add some features. While searching for better demo patterns I discovered this great collection with all the known oscillators and their period, it is made by Dean Hickerson. It is cool that changing the number of steps you can verify that the period is right. Some patterns are very interesting, others are just combinations of other patterns.

Things I hate about WebGL

Inspired by this post from Rich Geldreich, and after coding in WebGL for more than two years, I want to make a list of all the things I hate about WebGL graphics programming. Which doesnt mean I dont like WebGL, just that there are many fields to improve that should be addressed.

Coding C++ from the browser

Today I wanted to try a very basic web experiment that I had in mind for some time.
The idea was to code in C++ inside the browser and see the output right there.

My first 3D animated short

Sometimes when I get tired of coding I like to change hats and do something more artistically.

Last christmas I was approached by Anna Duriez from welovestudio.com to help her to do a video for the town of Saint Malo to greet the new year.

The idea was to do a short animated video that shows a little bit the key elements of the city in a ‘christmasy’ background, but we couldnt use snow or other cliche components because Saint Malo is a coast city, so we decided to play with other elements.

Pleasure.js, a fork from one of my apps!

Some years ago I coded an interesting web hack for the Music Hack Day 2011, a Freesound database explorer with visual feedback. For me it was just an excuse to explore more about the Canvas element in HTML5 so after the hack I didnt continue it, although some people told me it had lots of potential.

Today I discovered that somebody took the idea and polished and now it is in github. Check it out, the result is a very clear interface. I’m glad to see that one of my ideas went beyond me.

My LD27 entry won the second position in Graphics!

I was surprised but my A DEUS minigame made in 48 hours won the second position (from 1400 entries) in the graphics category thanks to the public votations.

Obviously I didnt ranked so well in the rest of the categories but that encouraged me to work harder next time and achieve a better position in other categories as well.

A DEUS: Postmortem of my LudumDare entry

This weekend (my last holidays weekend) was the Ludumdare 27, the compo where you have to make a game based on a given theme, alone, in 48 hours, without reusing existing code or assets.

I made “A DEUS”, an asynchronous multiplayer web game in Javascript/WebGL. You can try it clicking on the image.

I wanted to write a post-mortem with some of my thoughts about the game and the development process.

Playing with the Emscripten port of Box2D

Some time ago I had the idea of porting the concept of a great old game called Mindrover to the web, as an excuse to do something with my LiteGraph.js library (a javascript to create modular graphs similar to PD).

Motorclub, using graphs and physics

Mindrover is a game where you design your vehicle to fulfill some challenges. You cannot directly control the vehicle during the challenge, instead you must add sensors and thrusters around the chasis of the vehicle and wire them to react according to your strategy. A very interesting and fun game. Sadly it seems that the mechanics of the game havent caught up with more developers.
