Playing With Shapes

Didn’t make a lot of progress today and decided to play around with shapes instead. Here’s a heart -> https://codepen.io/shortdiv/pen/zYxGQBm?editors=1010

Back to Primitives

Geometry is the basis for drawing any shape in ThreeJS. As I covered in earlier posts, geometry in ThreeJS consists of vertices and faces, which can be defined by hand in order to create custom geometry. Of course, this task of defining your own vertices and faces is ambitious and requires a firm understanding of how math works in ThreeJS—knowledge which I currently do not have. To keep things simple, ThreeJS offers default 3D shapes known as primitives so you don’t have to grok geometry to generate common shapes like spheres and cubes.

Curveball

Most shapes in ThreeJS and WebGL can be created using primitives many of which, you can use to create composite geometries, like this really neat christmas tree. Creating complex and unique geometries however takes effort and can be difficult to achieve by simply compositing, mutating and ”extruding” existing primitives in ThreeJS. A better approach, as I highlighted in a previous post, is to utilize the methods like Geometry in ThreeJS that give you the flexibility of defining vertices and faces for custom polyhedrons.

Walking at angles

Walking at angles When drawing in 3D and even in 2D, we rely on shapes to make up a larger geometry, which then go on to form a more complex scene. This may seem rather straightforward but to a machine the task of drawing shapes could not be more complicated. This is largely because most machines only know how to render triangles. Take the humble square. Ordinarily, a square is drawn from point to point around the perimeter of the square, so in the figure below we’d draw a square from 1 → 2 → 3 → 4.

A Cube in 3d

Because we’re starting from the basics, this week we’ll focus largely on shapes and rendering shapes to the screen. This task may seem trivial but I assure you there’s a lot happening to occupy a week’s worth of content. To keep things simple, we’ll create our 3D images using ThreeJS, a JS library that abstracts a lot of the complexities of WebGL so you can write graphics with the power of JavaScript!

3December

At the start of 2018, I got the opportunity to be part of the first mini batch at the Recurse Center. Recurse Center is a self-directed, community-driven programming retreat in NYC aimed at attracting programmers who want to grow their programming chops in a rigorous yet, supportive environment. Students who attend Recurse generally come in with a dedicated project focus. This helps with setting a course and creating a clear purpose through the course of the term, which lasts anywhere between 1 week and six months.

Geocoding Data

A key step in the data visualization process is the conversion of data to the right format. When working with geospatial related information in particular, data needs to be in geoJSON to be accurately superimposed onto a map. In many instances, geospatial data available via Open Data Portals like data.gov is already in a proper format to be mapped. However, there are times when the available data needs to be cleaned and/or transformed into a more appropriate format to be useable.

Redirect Rulez

Redirect Rulez Browsers rely on URLs to access content on the web. One way to think about URLs is as a giant phone book for the web. When a browser wants access to a specific resource, it looks it up in the “phone book” and makes a request for it by visiting the address specified. However, like physical addresses, virtual addresses are not permanent and are subject to change. When a person moves irl, they often file a change of address at the local post office so that mail gets routed appropriately.

Predictive Web Performance

Some of the most cutting edge and effective web performance optimizations, like prefetch and preconnect, involve being proactive. We make predictions to determine where a user is likely to go next and load resources ahead of time so page load is as fast as possible. While there is somewhat of a science to making these predictions, thanks to analytics tracking and extensive user testing, they are still largely manual. Making an accurate prediction therefore becomes progressively more difficult as your site scales since there’s no sure way of knowing where a user will go next.

The Myth of 'It's Just Javascript'

If you’ve spent some time in frontend land, chances are you’ve heard someone say “it’s just javascript” when referencing a framework, library or snazzy new tool. While the phrase has an element of truth in it—a framework like React compiles down to JavaScript for instance—it often betrays the full picture. For one, a frontend framework like React or Ember often involves complex-ish tooling, templating systems, and high level architectural decisions around state management, and routing.
