Create a transition animation when new data is passed into H3Hexagon layer

[DaveMitten]

First time creating an issue, so bare with me and edits/questions to help reduce this to a refined question and let's get a result :)

Heres the layer rendering function:

	_layerRendering = () => {
		const newobj =
			this.state.locationData &&
			this.state.locationData.map(i => {
				return {
					longitude: i.longitude,
					latitude: i.latitude,
					price: i.year[this.state.year]
				};
			});
		return [
			new H3HexagonLayer({
				id: "h3-hexagon-layer",
				data: this.state.locationData && newobj,
				pickable: true,
				opacity: 0.15,
				wireframe: true,
				filled: true,
				extruded: true,
				elevationScale: this.state.elevationScale,
				coverage: 50,
				getHexagon: d => {
					let local = geoToH3(d.latitude, d.longitude, 12);
					return local;
				},
				getFillColor: [223, 25, 149], // fluorescent pink
				getElevation: d => this.state.locationData && Number(d.price / 500),
				//transitions: {
				//	getElevation: {
				//		duration: 3000,
				//		/easing: easeCubicInOut,
				//		enter: value => [value[0], value[1], value[2], 0]
				//	}
				//}
			})
		];
	};

It renders fine, it follows quite closely the example:
https://github.com/uber/deck.gl/blob/7.2-release/examples/website/3d-heatmap/app.js

Now you can see above, where I have tried to put a transition in. I don't understand enter. It's a brief explanation and has left me struggling to understand how to implement an animation.

My intended outcome is to have the current top of each hexagon to rise to the new data being set by the state. Then from here have a transition or animation that would use an easing to show an animation of the mark rising to the new top.

I hope that makes sense. I have seen it being done, but no access to the codebases or githubs to check out how to do it. I have a hacky way of doing it now, but i would like to follow deck gl as closely as i can get to the transitions.

With the link to the 3d-heatmap above, I have used the _animate from that code example to create an animation when the data layer is initially rendered. Then I reuse this code. It's hacky at best.

Any ideas?

Closing for inactivity. enter will only receive a 1-dimensional value since it's for getElevation, see https://deck.gl/docs/api-reference/core/layer#transitions

Right now deck does not support key-based object matching when performing transitions. You can track this feature request in #2570
