Gathering v38.0

Join us for our monthly gathering of creative developers, designers, hackers, makers and more.

#motion-graphics #animation #math #making #robots #electronics #art #installation #HOLO

7:00pm doors open. Come in and grab a drink from the lovely bartenders at Handlebar!

7:30pm Layer 3: Theoretical Knowledge: "Standing on the shoulders of giants" with Kevin Lam 

This month is part three of a three part series about programming motion graphics. Kevin Lam will give a series of talks about the concepts, math and ideas behind complex motion graphics. Demos will make use of EaselJS and the HTML canvas.

- Taylor series for modeling trig functions 
- Orthagonal polynomials (summary of Sony Entertainment Playstation division's R&D) 
- Using trig identities to compare precision of models 
- Precision vs performance trade offs of different sine models 
- Look up tables vs real time computation trade offs


8:00 Robot Craft with Nicolas Stedman

Robots are different from other technologies because they are physically dynamic and responsive. This offers unique creative opportunities, but also many complications. I'll discuss my experience working on them.

8:30 Print Scrn with Greg Smith
HOLO is a print periodical that chronicles emerging trajectories in art, science, and technology. HOLO editor Greg J. Smith will discuss the challenges of creating enduring media in an age of ephemerality, drawing on examples from the magazine’s recently released second issue and the team’s online platform CreativeApplications.Net

    Alright guys, I made a HTML5 version of the simple Asteroid Shooter that I will be demonstrating how to build: http://www.cineblueone.com/createto/asteroids/index.html You can view source to look at the javascript to see how it's made.

    This version of the game is not very memory efficient because it doesn't use an object pool. I just want to focus on several key core math concepts and not confuse anyone with additional concepts until a later talk. I would like to do another future talk focused on the topic of particle systems which will include the concept of object pools for memory management.

    For this upcoming meetup, I've decided that talking about theoretical math won't be very interesting or as practical. Instead, I'll be taking the previous math concepts learned and spend 15-20 minutes explaining and building this fully functional asteroid shooter game from scratch in front of you guys. Source code will be open sourced in a link after the presentation of course.

    Here's a sneak peak of the asteroid shooter game I'll be building: http://www.cineblueone.com/digiflare/asteroids/ - direct the ship's orientation using the mouse, click to shoot, use the A, D keys to move the ship left and right.

    This game will also serve as a basic introduction to the concept of computer graphic particle systems which I would like to talk about more in depth in a future presentation. If I still have time, I'll talk about my code interview with Ubisoft from a few years ago and talk about the particle system I had to build from scratch as part of the code test.
