kandi X-RAY | deck.gl Summary
deck.gl is designed to simplify high-performance, WebGL-based visualization of large data sets. Users can quickly get impressive visual results with minimal effort by composing existing layers, or leverage deck.gl's extensible architecture to address custom needs. deck.gl maps data (usually an array of JSON objects) into a stack of visual layers - e.g. icons, polygons, texts; and look at them with views: e.g. map, first-person, orthographic.

QUESTION
We are using deck.gl to visualize our data. It looks great, however, in the plot basemap, there are still the country names as labels.
In the API kepler.gl there is an option to hide the labels. We are looking for the same functionality in deck.gl
Does anyone know how to remove those from the basemap? Thanks

Answered 2022-Apr-11 at 08:19You can use CARTO basemaps with no labels, check docs here!

QUESTION
I have a polygon GeoJSON layer in my deck.gl map. To avoid having to reload many polygons in many user interactions, I would like to pre-load all polygons and then change their visibility. I tried to achieve this by setting the fill color (and also line color and line width, but there it's hidden in the functions) to null depending on the polygon properties.

Im trying to align a deck.gl PointCloud layer with a location on Mapbox. I tried modifying the position values and it's working but I was wondering if there is another simpler way to modify the layer orientation instead of modifying the data.
I used this code to define the layer :
...ANSWER
Answered 2022-Feb-17 at 13:00You should use the modelMatrix property on the Layer baseclass.
The transformation is done using a 4x4 transformation matrix for 3D space, which it includes both rotational as translation aspect. If you want to rotate along one particular axis, you can see the examples below.
QUESTION
I'm working on a configurable set of map layers with Deck.GL & React. I have a BaseMap component that I'll pass layers of data to as react children.
Currently, I have this:
BaseMap:
...ANSWER
Answered 2021-Jul-28 at 15:09The confusion came from a mis-understanding of how deck.gl's React component works & what those components really are (they're not react components).
Deck.gl's react component, DeckGL, intercepts all children and determines if they are in fact "layers masquerading as react elements" (see code). It then builds layers from each of those "elements" and passes them back to DeckGL's layers property.
They look like react components, but really aren't. They can't be rendered on their own in a React context. They can't be rendered outside of the DeckGL component at all, because they're still just plain deck.gl layers.
The solution here is to create a new map layer class just like you might in any other context (not a React component wrapping a layer). Docs for that are here.
QUESTION
The deck.gl MVTLayer inherits from Layer that has onHover enabled which together with pickable should give interactivity. I am trying to get interactivity to work so I can do a popup with the data I hover. But in below code, I can get the onClick event to fire, but not the onHover event. what am I doing wrong

Here is a code sandbox example where I am trying to display a map inside of a specific component. But, I am not able to get the deck.gl and react-map-gl divs to live inside their parent. instead, they spill out to the extent of the document body.

Answered 2021-Sep-14 at 17:09In order to allow the deck.gl component to take up the available space of the parent component you can add position: 'relative' into the overrides for your Box with an id of mapcontainer.

I have a project using a React, Mapbox, and Deck.gl stack. I'm trying to query the features on a styled map but am having trouble implementing Deck.gl's getRenderedFeatures function, even after looking at the documentation.
My current React component:
...ANSWER
Answered 2021-Jul-27 at 07:16Are you using MVTLayer right?
getRenderedFeatures is a method of MVTLayer class, you need to access it from here, not from the deck instance.
The logic could be:
- Render the
MVTLayer - Listen
onViewStateChangefrom the deck instance with some debounce - Then call
getRenderedFeatures
