h3 VS Cesium

It looks like the base Kontur dataset uses H3 resolution 8, and there’s a lookup table here. “400m” seems to refer to the edge length (which averages to 461m).

I can speak to quadtrees, but the primary reason for using this is that you need a geographic "dictionary" (not using the word map to avoid confusion with charts), and you're perhaps already using the H3 hexagonal grid system.

HexSet: is a way of storing a set of H3 cells in a tree, and doing fast (2-20 ns on my 2013 trashcan Mac Pro) membership tests. You must first convert the input data (e.g. GeoJSoN polygon) into H3 cells.

How can one read the code of the benchmark, then switch into virulent sarcasm mode without trying to understand the code? And seeing "+1" comments without any effort to understand is also disheartening.

The blog post had a link about the Go helper functions the author used. It lands on https://github.com/akhenakh/goh3/blob/main/h3.go This shows that the `FromGeo()` function used by the Go benchmark is a helper that calls transpiled functions. The benchmark code itself was of course not transpiled, so the sarcasm was unneeded and wrong.

If anyone wants to dig in deeper, the C function `latLngToCell()` calls 2 functions, see https://github.com/uber/h3/blob/master/src/h3lib/lib/h3Index...

Uber just released their library to perform geospatial indexing - https://h3geo.org/. This might be an useful building block for you.

My only problem is I can't tell if this is where the sphereical shape of the point is being defined: https://github.com/CesiumGS/cesium/blob/main/Source/Shaders/PointPrimitiveCollectionVS.glsl

The actual definition of a pointPrimitive

I'd like to use Cesium ( https://github.com/CesiumGS/cesium ) in a WordPress site. It's a rather large Javascript library, and I expect there are some intricacies around integrating it into WP's own Javascript. Has anyone tackled this before and do you have any pointers?

vue-stack-cesium - A minimal sample configuration project with CesiumJS and all the awesome vue features. The project contains many examples how to combine and use certain packages to get started.

We'll use CesiumJS to visualize the result, but you can use any library/engine that can take in longitude, latitude, and height.
