Hi @mzschwartz5 ,
My case is that, in my application, there are several layers to express different entities, such as those osm entities in openstreet map. They are rendered well.
Now, I need add a new Layer, which ara raster tiles coming from heatmap of vehicle trajectory in level 16. And I want to post-process blur these tiles only, not to effect other entites such as road in other layers.
I have tried the czm_selected by expend a get interface of pickIds of Primitive class, which mentioned by Shaders and selected primitives in PostProcessStage - #3 by Martin_Novak . It does worked but I found that if entities like roads overlap with the heatmap tile, roads will also be blurred, which is not my intention. It seems that czm_selected is a mask mark to target primitive in pixel level, which will effect other overlapping entites. Is my understanding right?
I’m interested in your solution, can it solve my situation? If then, can you show me some demo how to deal with the overlap situation.
Thank you for your apply! Best wishes.
