    Is there a way to position the camera/projection for a Tangram map in a similar way to navigation apps? E.g. https://raw.githubusercontent.com/mapbox/mapbox-navigation-ios/main/docs/img/navigation.png

    I'm still working through this library, but I'm sort of feeling stuck. I need to be able to animate a circle growing a certain velocity from a point. It seems there isn't a circle polygon, but maybe drawing a circle could work, but then how would I animate it? The other option seems to be a shader, but I'm not certain how I would place a shader on the map and have it render at a specific point? I've been searching for hours. Please, if anyone has any suggestions or examples, that would be great!

    Like there is a shader circle example: https://github.com/tangrams/blocks/blob/gh-pages/shapes/circle.yaml
    But then how do I place that on my map with Tangram ES?
    Then I assume I would have to figure out how to use shader code to animate the circle

    @thertzelle what about rendering the circle using a Leaflet layer on top of tangram instead of via webGL? Then you should be able to use CSS transitions. oops, I didn't read to the end - realizing you're using ES, not web
    I think you would need to pass a new uniform corresponding to your animation parameter

    Can you say a bit more, or is there an example describing what your talking about? Thanks for the response!

    Is Tangram JS and ES production ready? As in why would I choose Tangram over Maplibre?

    Hello all, I have a problem. I want to overzoom a vectorial map that have data available only until zoom 8 on a mobile Device that run a UBUNTU base Tangram ES SW on it. All ok until zoom 10 but if I want to overzoom more, the icons and texts have rendering issues..like here:

    Do you know which can be the cause? Is possible my mobile Device OS have some limitations or bad configs? Or my scene.yaml is not ok?
    On PC viewer and Tangram Web all ok with my scene and map

    Is there a way to make an animated growing circle in tangram-es, whitch is used in gps position like mapbox
    Rob Howard
    @warpedgeoid
    @ccxxbb You should be able to do this with a custom shader.

    Hiya!
    How can i "ask" tangram to keep the original angle of a sprite?

    For example i have a fix angle 45, want to see this sprite always in this exact angle, regardless what the current view is.
    So basically i don't want it to be rotated at all.

    Cheers!

    Is there some documentation on how to make mvt from geofabrik downloads?
    So that they can be used with tangram-es default styles (e.g. the scene.yaml in the repo of tangram-es)
    Brandon Liu
    @bdon_gitlab
    @mathisloge take a look at https://github.com/systemed/tilemaker ; you could customize the tile creation via Lua to match the tangram/mapzen cartography

    Did any one obsered that loading a Vectorial layer for example on low zoom (for example zoon 3-5) and set max_zoom: 5 (max zoom to request tiles) and max_display_zoom:18 to overzoom last available tiles set untill zoom 18...there is a huge memmory leak (I can easly reach RAM limit even on a PC with 4 GB RAM only by zooming IN and zooming out more times). Each time the RAM increase until limit is reached. It seems a n issue in Tangram rendering overzoom textures
    I used latest version available on GIT to obtain this issue(is also obtainable on older versions). Is there a special settings I must consider or this is a known issue?

    Exist possibility to upload a grid map? I have 5x5 degrees coverage for every map and I want to upload several in the same scene.yaml. The maps has same layers and same data type. Only covered surface is different. I can view concomitant several maps of the same type?

    Can tangram-es render raster images with a specific bounds? (not tiles, but a single areal image)
    I have seen options for this in tangram-js but i cant find any hint regarding such a feature in the tangram-es code base. i just want to be sure i did not miss anything :)
    Cheers!

    Hello All!
    I have a question regarding collide on icons. It seems that only by opening tangram on a certain zoom level, sometimes it collide some icons, other times other icons (without moving on map or do anything else). Is collision done randomly? Is there any solution to have always same icons collide? Because if we zoom in and zoom out on same location, icon first presented dissappears and other icon is displayed.

    I plan to have a Pi with GPS attached. I'd like to serve a local webpage with a Map and GPS pin. Does Tangram help with this? Or is there another project I should look at?

    Hello , We have some LineString Geometry Objects in geojson format (longer or shorter lines) with Depth attribute for each line. We create mbtiles from it and show in Tangram ES. When we want to show a text label on it with Depth attribute , Tangram ES fill whole line with this depth attribute(see picture). Why this happen? Is there a way to avoid this fill mechanism without use collide=true in scene.yaml?
