I’m looking to render a heatmap onto the Cesium globe and I still want the base layer visible underneath. Currently I’m using H3 to render a around 6 thousand hexagon entities onto the globe to get an approximation of my heatmap but I want to use about 50 times more granular data and I’m concerned about performance when rendering ~290,000 entities. (In fact, trying this crashes the browser tab)
I am considering rendering the heatmap as a global texture and applying it to the globe but I am concerned about distortions and projections. Are there any examples of rendering a texture to the entire Cesium globe? Is there maybe a good format to save my data in for use in a shader?
