First, there was written language. Shortly after came type, a way of optimizing written communication through the reuse of identical characters. Typesetting might have been used as far back as 2000 BCE: there’s evidence that ancient Mesopotamians used a form of typesetting to stamp cuneiform impressions on bricks.
The point is that humanity has a long history of caring a lot about the appearance of our written communication.
In my previous article, I wrote about the challenges of turning square pixels into curving, irregular shapes and how anti-aliasing can help. …
The world is full of slanted and curved surfaces. The gentle slope of a hill, the glowing circle of the sun, a handwritten scrawl on a chalkboard.
For computer graphics, the building block for representing these images is the pixel — a little block of light. A typical screen uses thousands of these little blocks to represent a spectrum of images. But we run into problems trying to represent round shapes with square objects: jagged edges.
In Part 1 of this series, we took a look at blurry vision and blurs in photography. In this article, we’ll take a look at how blurring techniques are used to improve image quality in computer graphics. …
In this multi-part series, I provide clarity around blur, from vision to photography to effects in app and game design.
When my sister was 10, she convinced herself there was something wrong with her eyesight. She decided she was nearsighted.
I was skeptical. I had no idea how being nearsighted might benefit her, but I suspected there was some sort of angle — perhaps she found a way to get out of math class.
Eventually, my mother did what any parent living in a rural area of Arkansas would do: she took us to the closest Walmart to get our eyes checked. My vision was fine, or so I thought, but there was a two-kids-for-price-of-one discount, so I hopped in the truck and we drove half-an-hour to the Walmart in Hot Springs. …
