Hi,  
I need to create a glow effect in the scene . A search in the forum gave me this link:

[https://github.com/AnalyticalGraphicsInc/cesium/wiki/Screen-Space-Rendering-Details](https://github.com/AnalyticalGraphicsInc/cesium/wiki/Screen-Space-Rendering-Details)

This mentions a built in filter for glow with a glow buffer. Is this a ready to use plugin and if so how can I use it ?

Or do I need to create my own implementation of the glow filter using `czm_FilterInput` and `czm_Filter.`

Joanita,

That wiki page describes plans for screen-space post-processing effects. These are not officially in Cesium yet; however, there is something useable in the [postprocess-hook](https://github.com/AnalyticalGraphicsInc/cesium/compare/postprocess-hook) branch. To create a glow filter, you could base it off one of the other .glsl files.

Thanks Patrick,  
I’ll try that out.
