Pointcloud raytracing

[kpoeppel]

First draft for integration point cloud data. Definitely not mergable, but as a first point of discussion on how to progress.

[kpoeppel]

@FlorianK13 @MartGro , what are your opinions? (regarding how exactly to integrate / UX wise etc.)
I would like to finish this soon, as I need to focus on another side-project now.
Otherwise feel free to update on your own.

1. I get this error:
   Uncaught (in promise) RuntimeError: Aborted(CompileError: wasm validation error: at offset 4: failed to match magic number)

• This error is still there even if I download the corresponding .laz file

2. I get this error:
   Uncaught (in promise) Error: Can't find end of central directory : is this a zip file ? If it is, see https://stuk.github.io/jszip/documentation/howto/read_zip.html

• I solved this error by deleting line 235ff from simulation/download.js

[FlorianK13]

Still get the same error:
Uncaught (in promise) RuntimeError: Aborted(CompileError: wasm validation error: at offset 4: failed to match magic number)
It comes from the laz-perf.js package and the createLazPerf function.

In Edge the error message is: Aborted(CompileError: WebAssembly.instantiate(): expected magic word 00 61 73 6d, found 2e 2e 2f 2e @+0)

Running on windows? It might be that you do not get the symbolic link. And/or you have to re-run npm install to install laz-perf. The .wasm file has to be inside the public/static/ folder somewhere in the end to get it running.

[FlorianK13]

I get a laz-perf.wasm in static/js folder. I also rerun npm install.

Yes It is on windows. The error persists, still the wasm validation error.

@MartGro Is it running on your laptop?

[kpoeppel]

We resolved it now. On windows one has to manually copy the symlinked file node_modules/laz-perf/lib/web/laz-perf.wasm to public/static/js.

The latest updates integrate the translations and make it possible to opt out of laser data. Also laser data is loaded now from the LVA Bavaria proxied via our website - so all of Bavaria is usable.

From my side this would now be ready to merge. Any further comments?

@FlorianK13 @MartGro ?

Restarting the simulation via the arrows results in the error: 'Uncaught (in promise) TypeError: coordinates must be finite numbers'

I cannot reproduce. Did you pull the latest commits? Please provide more detailed instructions on the error.

Sorry, forgot to pull the commits 🙃

Is it right / intended that the raytracing is only done with the points? At least I get this intention when I look at 'Rathaus Augsburg' and show the pointcloud. Then, at the right side of the building there is no real shadowing even though the next building is very close (The wall of the next building only has no points from the pointcloud)
