2D Perlin Noise Wave graphics demo in Unity (PC) 3440x1440 UltraWide 21:9 resolution. 2,500 spheres in a 50x50 array.

52 Weeks of Sharing:

Inspired by a photographer friend, Laura Totten, who published a photo for every day of the year 2019, I am going to share a piece of graphics programming for every week of 2020! I am using the, currently unpopular, hashtag #52weeksofsharing on YouTube and Instagram. Feel free to join.

Unity's Perlin Noise:

Unity's implementation of Perlin noise appears to be a common naive implementation that is mostly likely VALUE NOISE. Perlin noise is actually a form of GRADIENT NOISE which is the interpolation of GRADIENTS (first derivative angles also measured as normals), whereas VALUE NOISE is the interpolation of VALUES (end values). Unity's implementation is a common misstep. It has strong (poor randomization detectable by human) artifacts, such as lots of zeroed out locations. In other words, it does not look good and is a misrepresentation of the quality of real Perlin noise!

YouTube Resolutions Explored:

I am exploring uploading videos in 3440x1440 60Hz, and the way YouTube handles 21:9 UltraWide resolutions can be confusing to the end user. To get 3440x1440 display output, you have to select "2160p60 (4K)" rather than "1440p60". To be clear, to get 1440p you have to select 2160p, not 1440p. How does this make sense? Check out my findings below.

YouTube 21:9 UltraWide Resolutions (Quality Settings vs. Actual Resolution):
- 2160p displays 3440x1440.
- 1440p displays 2560x1072; Note: 2560x1440 is a 16:9 widescreen resolution.
- 1080p displays 1920x804; Note: 1920x1080 is a 16:9 widescreen resolution.
- 720p displays 1280x536; Note: 1280x720 is a 16:9 widescreen resolution.
- etc.

It appears YouTube lets you choose resolutions based on height (2160p, 1440p, 1080p, 720p, etc.) but selects the output resolution based on the width of that height's 16:9 widescreen version.
