Now that we have our framework for animation we can make things a bit more fluid. Let’s use a velocity to update the positions or coordinates of each dot rather than just throwing random numbers at them. We can then adjust the velocity or rate of movement and it will be a much more natural [...]
Here’s a quick and easy update. I tend to think of frames in animation and rarely do I think of milliseconds. I’m going to make a var called fps and it will be used to calculate our animation rate. interactive physics animations via javascript & canvas | 09. $(function () { var canvas, [...]
Thus far, we’ve been doing lot of setup and it hasn’t been very visually exciting. Now we start the fun stuff! Adding motion! Before we just has a draw function, but now we’ll add a function that will control the animations and we’ll also need a way to execute code repeatedly over a period of [...]
Here’s an interesting rendering I found when I was playing with drawing multiple dots. interactive physics animations via javascript & canvas | 07 B. $(function () { var canvas, context, width, height, x, y, radius = 25, clickX, clickY, drag = false; var total_dots = 25; [...]
This step we’ll add a variable to hold the total number of dots we want to create and use it in our for loop that creates the dots. We’ll also give the dots a little more randomness by varying the size with a radius value. interactive physics animations via javascript & canvas | 07. $(function [...]
Here we’re going to get more into the interactive programming on these dots. We started with one dot that was draggable. This update applies a drag/drop code to each dot object with some logic to keep track of which dot is being dragged. This is quite a bit different than accomplishing the same thing in [...]
Now we’ll apply this object oriented programming to each dot and give them all random placement. interactive physics animations via javascript & canvas | 05. $(function () { var canvas, context, width, height, x, y, radius = 25, clickX, clickY, drag = false; canvas = $("#canvas")[0]; [...]
This time we won’t make the canvas any different visually, it’s more just cleaning up the code. We’re making the circle into a dot object, then later it will be easier to keep track of it (and any others). interactive physics animations via javascript & canvas | 04. $(function () { var canvas, [...]
I’ve been playing with canvas and different javascript drawing libraries a lot lately in my projects at work. I’ve been antsy to play with the techniques I’ve learned and apply it to some more interactive experiments. Much like my last series on generative art in flash, but this will all be in javascript! In case [...]
I’ve been busy hardening and improving my video player lately and had so many updates for it I decided to upload it to activeden as a new file altogether. After some final bug fixes and testing it’s been approved for sale. I think it’s a huge improvement over the last video player. The video playing [...]
Here are my slides for my WordCamp Atlanta presentation, From PSD to WordPress Theme: Under the skin: PSD to WP on Prezi
I’m proud to announce that I’ve been asked to speak at WordCamp Atlanta this year! WordCamp will be held this weekend and hosted at SCAD Atlanta! My session is titled: From PSD to WordPress Theme: Under the skin. Obviously, I’ll be focusing on themes. We’ll look at what they are, what they can do, how [...]
Zero images is something that always gets me excited, I really like these arrow button styles! I like the css used more and the hover/active states too, nice css3 transitions. via Adobe-like Arrow Headers | CSS-Tricks.
After playing with the settings in my experiments I found a few settings I liked and wanted to develop further. The first was snow! An added bonus I was able to work on a project just for the holidays and used much of this code in it! I looked around the web and saw a [...]
Mat discusses the options for getting responsive images along with responsive designs. We can use various means (server-side, client-side, mobile-first, html5 data attributes, cookies…), but none are fully satisfactory, especially with new browsers prefetching images before cookies can be set or html is even fully read and parsed. He states that bandwidth sniffing is… a [...]
Here’s a great article about the process of responsive design & mobile first design and how to practically use them both in a project. This site is a proof of concept for many of the ideas described in Rethinking the Mobile Web or (Mobile First Responsive Design). via Yiibu – About this site….
Here’s a great tool to make responsive grid layouts. Thanks to Erskine Labs! Introducing Gridpak | Erskine Labs.
Here’s a great little script I found useful today as I was working on having dynamic effects applied to javascript via canvas. “The canvas element provides scripts with a resolution-dependent bitmap canvas, which can be used for rendering graphs, game graphics, or other visual images on the fly.” Thanks to the canvas APIs I was [...]
I'm Evan Mullins. I'm a web designer and am very interested in the intersection of art & technology, user experience, and interactive design. I like contributing to make the web incrementally a better place. I love simultaneously solving problems & making things aesthetically brilliant. circlecube is my interactive design site chock full of tutorials, critiques, techniques, technologies, ramblings and a playground of experiments.
