cesiumgs / cesium-workshop Goto Github PK

Installed the workshop to see if I can use it for teaching Cesium, but found this error when starting up from both npm and python:

An error occurred while rendering. Rendering has stopped.
RuntimeError: Vertex shader failed to compile.  Compile log: ERROR: 0:50: 'w' : vector field selection out of range

I am on Kubuntu 22.04. I tried installing WebGL drivers to fix this, but it didn't (and Cesium works in general for me as well, so it's not something across every Cesium application)

This had to be merged quickly for FOSS4G, but could probably be improved.

1. Do an extra round of review
2. Fix the code that toggles the neighborhood visibility (when checked and unchecked, try changing the 3D tiles styling to transparent and default)
3. The loading icon is buggy.
4. Double check the PR thread for comments that I may have missed.

The workshop includes instructions for signing up for an ion account, but then they have no way to access the NYC tileset because it is not in the asset depot.

@mramato is this something we can make available for users to add to their accounts?

If you just open the workshop right now, you'll see a black overlay preventing you from interacting with the app.

This is because the main tileset hasn't loaded yet, and the overlay is a loading indicator. However, the tileset will never load because it looks like the default token here has expired?

But that's okay! You can add in your own token by replacing:

Cesium.Ion.defaultAccessToken = '<YOUR ACCESS TOKEN HERE>';

So then most things load (imagery etc) but not the tileset id 3839 presumably because my account doesn't have access to it?

So the loading indicator never goes away either way.
