Interpolate Points to Raster (Thiessen & IDW) in QGIS

Covers, interpolations, and “reimaginings” that mistake recognition for meaning. From Heart to Nine Inch Nails, a tour of pop songs that lost the plot—and the rare ones that actually earned the risk. Some covers reveal new truths. Most just tell you to buy the record.

"Shape of You" is a song by English singer #EdSheeran. It was released on 6 January 2017 as one of the #doubleLeadSingles from his third studio album ÷ (2017), along with "#CastleOnTheHill". The #dancehall & #RAndB infused song was written by Sheeran, #SteveMac and #JohnnyMcDaid. Due to its #interpolation of "#NoScrubs" by #TLC, #KandiBurruss, #TamekaTinyCottle, and #KevinShekspereBriggs are also credited as writers. The song was produced by Sheeran and Steve Mac.

🎨 Oh wow, another #techie #bible on how to make your #laptop sweat by #rendering #mesh #gradients with #RBF #interpolation. 🤓 Because everyone knows, nothing says "cutting-edge" like having 17 tabs of #Stack #Overflow open while praying to the gods of Notion that your code doesn't crash your computer. 🚀

In today's episode of "Math #Mystifies #the #Masses," we dive into the riveting world of #probability #density #functions and #interpolation factors—because apparently, nothing screams excitement like calculating how an "entropy bulge" curves upward. 📈🤯 Spoiler alert: It's concave!

With the new folio comes my first article about the linear interpolation and what I learned building the Interpol javascript library.

I hope you enjoy it as much as I enjoyed writing it.

Another non-orthogonal designspace. Please observe three drawings for the big size and only two for the small. A straight line for the same stem just because I can. Smooth and continuous. Images generated from working code. I know you're curious, I can make more. #interpolation #experimental #designspace #math #somethingnew

Look here. This is a method to make smooth and continuous non-orthogonal designspaces. In this example: 4 masters "on the outside" and 3 floating intermediates. (The shapes are from MutatorSans and only illustrate the extent of influence.) #interpolation #experimental #designspace #math #somethingnew

A couple of 2017 tests/prototypes using Shepard/IDW interpolation[1] to compute "soft" voronoi cells. Reposting this after @Danpiker was mentioning this method for 3D modeling in recent days. Coincidentally, these tests were for something v. similar, i.e. outsole traction pattern geometry generation — the exponent used in this method acts an easy-to-grok parameter to control softness/sharpness & level of detail... Unlike these examples, which are only using point samples and colors, the idea was to interpolate between line geometries to create a relief surface. E.g. applied to an outsole, we could configure the interpolation to produce softer shapes in the heel region and more detailed ridges in the front foot, where traction is needed most... In the end I didn't use this specific interpolation method for performance reasons and switched to another approach to compute an SDF for v. similar results (see recent posts from yesterday).

Live #RIFE video framerate #interpolation has been available for a while but to my knowledge there is still no out of the box player on linux that uses it.

The "simplest" way I found so far (on arch):
- Compile mpv with vapoursynth support (will enable automatically if vapoursynth is installed).
- Install this implementation: https://aur.archlinux.org/packages/vapoursynth-plugin-rife-ncnn-vulkan-git
- Save this vapoursynth script https://gist.github.com/ChristophHaag/a1185776cf62a5e8e077bf04ea9de34f
- run mpv -vf=vapoursynth=~/VapourSynth-RIFE-ncnn-Vulkan_script.py video_file

I wrote a command line tool to stretch #SRT subtitles between two time codes measured in a movie file, e.g. the first and last line of dialogue in the movie.

So when you have a SRT file that is at a slightly different „speed“ or your movie has some extra titles at the beginning, the tool can adapt your SRT file to that.

My knowledge of #font #interpolation and #variablefonts axis mapping made this really simple ;)
