Hi I'm experimenting with the new CustomLayer and using three. If I understand the projectionMatrix that gets feed to the render function correct it is somehow included in there.
But I don't know how to retrieve it from the 4x4 matrix if it is even possible. Is this correct? Thanks for the feedback indus! Would you want the camera position and rotation as separate values or a transformation matrix that incorporates them both?
So position would be the mercator coordinates of the camera and rotation would be a euler angle? Is there anything else you would need that we aren't providing? Not yet, but we should. We don't currently store the position of the camera anywhere because we're specifying the camera as what it's looking at instead of where it's looking from.
If is useful for this, I'd be happy to pick the PR up and get it merged. I'm not sure I want mercator coordinates for the position but world coordinates as a vec3 based on the gl context.
In three. I mean you don't have to do it like three. If you would provide them seperated it would be pretty easy to get the position and the rotation of the camera from the viewMatrix. Right now it is not so easy, and until now I haven't found a way how to do it. An idea I have right now is to multiply the inverse projectionMatrix like so ; the values are in map.
I would guess that it won't be a big benefit for the sort of implementation problems I tried to describe. In my case I'm not dealing with coordinates but only gl-units there would be additional transformation steps involved that require more helper functions. In my understanding the splendid CustomLayer implementation should be pretty low-level but easily accessible for WebGL enthusiasts.
I had success with decoupling the provided viewProjectionMatrix into a projectionMatrix and a viewMatrix. And the Float64Arrays could be reused. After all I would still prefer to get projectionMatrix and viewMatrix passed to the render function as two seperated values; they could be mutiplied by the user if needed.By: Ryan Baumann. Our mission is to build incredible developer tools that help us understand and explore our world.
This means developers can add more types of data to their maps — with less code and higher performance. For those new to visualizing data with deck. This toolbox is used to visualize massive datasets without compromising performance, from mapping hundreds of millions of trips as a ridesharing company to analyzing network models and cellular coverage as a telecommunications company. Custom Layers works with popular WebGL rendering libraries like deck.
Before Custom Layers, visualizations with origin-to-destination great-arc circles were difficult to create. The visualization below shows US migration patterns between cities. Mouse over each city to visualize the volume of people moving to other areas of the US.
Blue lines indicate net migration into a city, while red lines indicate net migration out. Not only can users clearly see city labels above their data, but developers can create this visual by adding a deck. To add arc layers to your Mapbox map, follow the example from deck. Prior to Custom Layers, developers had to manually work with coordinate matrix projections to synchronize two WebGL canvases for the map and the 3D model. Now, developers can control exactly where the model is placed in the scene, and Mapbox handles the synchronization of the model with the map while the user pans and zooms.

This is quite a common request and having an official example should help point people in the right direction. I'm open to using something else if anyone has anything better, like a detailed skyscaper, but I think it's more important to get an official example than be held up by what it looks like. This is great! Perhaps there's an easy way to simplify the mesh in the GLTF data?
I agree that this example should use a minimal model, I'm more concerned about the load time of the example. I've not been able to find a good sample model yet, I think it's better to at least get this example out there, and can follow up with a change of the model down the track to use something simpler.

It exposes methods and properties that enable you to programmatically change the map, and fires events as users interact with it. You create a Map by specifying a container and other options. Or you can use one of the following the predefined Mapbox styles :. Tilesets hosted with Mapbox can be style-optimized if you append? Learn more about style-optimized vector tiles in our API documentation.
Gets and sets the map's access token. Gets and sets the number of web workers instantiated on a page with GL JS maps. By default, it is set to half the number of CPU cores capped at 6. Make sure to set this property before creating any map instances for it to have effect. Gets and sets the maximum number of images raster tiles, sprites, icons to load in parallel, which affects performance in raster-heavy maps.
Sets the map's RTL text plugin. Necessary for supporting the Arabic and Hebrew languages, which are written right-to-left.
Mapbox Studio loads this plugin by default. Gets the map's RTL text plugin status. The status can be unavailable i. If the status is loaded and the plugin is requested again, an error will be thrown.

How can I get the texture to look right on this Object in the Mapbox view?

I can also see you have the same texture on both the diffuse and bump channels, Try taking the bump map off and see what results you get. Or maybe just lowering the bump factor.

Mapbox GL JS
Email Required, but never shown. The Overflow Blog. Featured on Meta. Feedback on Q2 Community Roadmap.By: Ryan Hamley. The latest GL JS release v1. The highlight of this release is the within expression, which allows developers to check whether or not a feature is in the bounds of a GeoJSON polygon. The Concord to Boston route and labels are colored red because the expression sets red as the fallback value when the features are not contained within the Maine polygon.
This shifts the visual center of the map to match overlaid UI elements on your page, such as sidebars, headers, and footers. Different padding values can be specified for each side of the map for granular control. The Map queryRenderedFeatures method returns a list of visible features in a geographic area. Previously, when a feature used an expression, queryRenderedFeatures would return the expression as-is.
With this update, queryRenderedFeatures will evaluate the expression and return the result, which makes debugging expressions easier and allows expressing the evaluated result within GL JS. This update also improved performance when queryRenderedFeatures evaluates many features at once. These and other improvements are available today to give you more tools to customize your map visualizations on web and mobile in the Maps SDKs for iOS and Android.
