Shaders on buildings

[mogmog]

I have recently discovered the library Tangram which facilitates using maps and WebGL together, and they have some very pretty looking shaders on the sides of buildings -

All sorts of documentation is available here.

I am trying to work out if I can achieve something similar in Deck as I am fairly heavily invested in the Deck world and have more familarity with it.

Which Deck layers would be the right ones to us to work towards these kind of effects?

Layer extensions allow you to inject custom code into a layer's shaders: https://deck.gl/#/documentation/developer-guide/writing-custom-layers/layer-extensions

If that isn't enough, you can also create fully custom layers (optionally subclassing existing layers) that give you (almost) full control over GL calls: https://deck.gl/#/documentation/developer-guide/writing-custom-layers/writing-your-own-layer

Extending or subclassing the PolygonLayer (which is used for the buildings in the example on the deck.gl site) could be a way to achieve similar effects.
