Sandcastle has long been a cornerstone of the CesiumJS developer community. We use it for showcasing features, sharing ideas, learning, prototyping, experimenting, and validating code. Its accessibility has played a key role in the success of CesiumJS and the community. To build on that success, it…

Some details about the connection between the “Sandcastle” (as a “core functionality”) and the actual Gallery (that contains many sandcastles) still has have to be sorted out. But one functionality that I wondered about is in how far the Sandcastle could be “fed” with other galleries. Specifically,…

Hello, I love the Sandcastle, but one of my pet peeves is that if I am experimenting in it and want to do something else for a while, it keeps running in the background but I don’t want to close the tab or bother with saving the code. My current work-around is to add return statement at the start o…

This ^ is somewhat related to an earlier post … at least indirectly. You’re talking about some “stop” functionality. And I noticed that this is particularly important when you accidentally have inserted something that prints many console.logs: It can easily happen that a tight loop floods the consol…

would be cool if it used OGC Geopose

Thanks for the idea @xmitter . We’ll keep it in mind. I could see a benefit to have a “unload viewer” type feature but we’ll have to see how it could be worked in. We’ve definitely already been thinking of ways to try and mitigate the problem of lost work when leaving or having the tab crash. My c…

[image] Marco13: It can easily happen that a tight loop floods the console with messages, up to the point where it’s neceesary to kill the browser tab to “recover” from that. I’ve been playing with an idea in my head to expand on the “logging” capabilities of Sandcastle. I think there could b…

Some sort of “variable watch”, like in a debugger? This could probably be useful for certain debugging tasks (but would not replace the generic console log forwarding). I don’t know how difficult that could be to integrate, or whether something like that may become less urgent when there is an opti…

I regularly use the Sandcastle, so I’ll just add some of my reoccuring thoughts. :slightly_smiling_face: “Better search” is already mentioned in the post. I’d just like to add to that, because that’s a pain point for me. I’d love to have a setting to make the search bar only search the code, onl…

you try using the way less CPU and GPU taxing requestRenderMode, if it not breaks core functionality of your demo. And manage scene.requestRender() manually when needed. const viewer = new Cesium.Viewer("cesiumContainer", { requestRenderMode: false, }); 5+ session open without hearing a fan or …

yes, this would be nice if it was managed by sandcastle UI

Thank you everyone for the great feedback so far! For anyone following this thread I just opened a new one with a preview of the new UI design. We’d love some feedback how it looks before it’s completely finalized. Please take a look and let us know what you think!
