I'm working on 3D web-GIS of an urban area. 3D buildings (with texture) were created in Arcgis and I'm looking for the best solution to display this 3D model on the web. I tried Cesium but I couldn't convert the KML file to CZML. What should I do to convert KML to CZML? Is there any other solution to display 3D buildins on the Web
You could use the gltf format, which basically is JSON.
A converter script can be found on the gltf github page. Also you can convert files online on the cesium webpage.
Cesium provides a function to load gltf files named "Model.fromGltf" as described in their documentation.
Three.js offers the possibility to render gltf as well. You can find an example on the gltf github page as well.

I face a very strange issue in Google-Earth Pro (desktop client) when I try to display a 3D model "indirectly". Let me explain a bit more.
I try to make life easier for our users by creating a KMZ (=zip of KML) containing only networklink (to other KMZ file in a S3 bucket with presigned links).
These KMZs are very simple (mostly polygons) but one is containing a 3D model, in COLLADA format from Google SketchUp 8 (compatible with GE Pro), including textures files (png) beside. The whole pack (KML + collada + textures) is zipped to a KMZ file.
If I use a KMZ pointing to local KMZ files through the networklink flag : no problem at all. But in my case where I use S3 links, all is working but the textures. The 3D model itself is fine otherwise.
Any idea about how GE Pro is parsing / caching networklinked files to solve this issue ? I guess it is a problem of local path since the content of the file is displayed.
I am using draw2d javascript library for drawing predefined shapes and custom shapes in it's canvas.
As I don't have any example made yet, I am trying to copy from it's documentation but doesn't seem to find a good way to research it as it contains a whole lot of it.
Here is the circle example.

and here are some more documentation with examples.

I have premade shapes with html and css and I am trying to drag and drop and render them on canvas like these in this image. Also when dropped, they should have input and output ports too.
Is it possible to convert this html/css to draw2d shapes?
So here this is made possible via extending draw2d's SVGFigure and thus we have ability to provide custom svg to render it as a custom shape.
Below links were useful in this context.

i am trying to build arcgis scene with my custom 3d models with ModelSceneSymbol but when the model finally loaded(.dae format) it appeared pure white when i explicitly designed it red, also most of the other formats like .fbx,obj etc. don't seem to get rendered on the scene, can anyone give me a solution for the color part alone, i am using vectary for 3d model creation btw
We are looking at using the Forge Viewer for a project to display and markup plans, etc. (for now just 2D, 3D may be added in the future). For some of these items we will have DWG Files that we can convert using model derivative API so no problem there. However, the client also has quite a few existing drawings saved in svg format from their legacy system.
The question is if there is a good way to convert those base svg files into svf that we can display as the 'main' drawing/view in Forge Viewer. I have found things about creating a markup layer from an svg file, but that's not really what we want. We would be using markups to have the user draw on top of the plan with their own tools and place markers, etc. but the main drawing should be from the svg file that they have.
Forgive me if this is simple but I'm fairly new to the viewer and model derivative API so I'm not figuring out how to make this work.
There is no translation support for SVG, to generate an SVF model out of it.
You could either
a) use the SVG inside a format that we support (e.g. DWG - perhaps place the SVG in it using Design Automation API) and translate that to SVF
b) load a dummy model as shown here, and then add the SVG as e.g. markup
I'm currently building a web application with Openlayers that draws routes en points of interest on a map. This map needs to be saved to a file on the server (.png of .svg), so it can be embedded in a .pdf file. The route and POI information is available as KML file.
What is the easiest way to do this?
You have several options:
Directly export your OpenLayers map to a PNG or even a PDF on the client-side (see these two examples: png export and pdf export).
Use wkhtmltopdf to export a HTML page containing an OpenLayers map to a PDF (on the server-side).
Use MapFish Print 3 which is a print server to generate PDF reports containing maps. You would create a report template and configuration and then send a print request containing the geo-data that you want to print (e.g. tile layers or GeoJSON data).
