Heat map and Cesium

[Luis Mendes]

Hi there.

Doesn't Cesium have a native Heat Map?

I am using EXTJS with Cesium and I've found heatmap.js and an api on github so i can draw a heatmap on Cesium, but I think it is not enough, I need the variable Time to be present so the heatmap can change over time.

I am hopping that Cesium have a native Heat Map and I just can't find it..

Can anyone help me?

4. The Cesium version you're using, your operating system and browser.

1.5

Thanks!

CesiumJS doesn't have a built-in heatmap visualization, but I found this GitHub issue discussing it:

https://github.com/AnalyticalGraphicsInc/cesium/issues/2208

Looks like it wouldn't be too hard to implement yourself based on Matt's suggestions there. Note how he says "For dynamic heatmaps, you should be able to use a CallbackProperty to return a different one each animation time".

It'd definitely be a nice feature to add into Cesium, so if you do get it working we'd definitely appreciate a contribution! I bumped the GitHub issue so everyone knows it's still a requested feature.
