I want to display cesium clock and timeline widget inside a different div container outside of the cesium container. With the help of this link I've created a separate clock widget and applied animation on an entity. Animation is working but the clock widget is not working. It seems like default clock widget is working not the newly created. Sandcastle link

I want to change background image of sky providing custom image but it is not changing

I want to fix the minimum size of 3D globe such as if user decreases the size through mouse it should not decrease beyond some fixed value.

Problem

I am a bit confused on how Cesium calculates geodetic and geocentric surface normal. Planes, generated from calculated normal do not actually tangent to ellipsoid surface in a given point, more then, the plane created from geodetic surface normal is just the same as one generated from geocentric surface normal.

Example & why do I need this

In this Sandcastle XYZ axis along with planes that should be tangent to ellipsoid are drawn when you click on the globe surface.

What I need is to get an XY plane tangent to Ellipsoid at given point and then project other points onto this plane. The problem is as I see the plane is not tangent to ellipsoid at all.

By the way - when I use built in method: Cesium.EllipsoidTangentPlane(); I also get strange result - plane is still not tangent to ellipsoid and also floating somewhere in space. Here is sandcastle.

Appreciate any help because I do not understand what happens here.

I want to disable the sun effects for all models presented in Cesium viewer when I manipulate the current time. I would like all the models to be bright all day long.

Tried to use the (enableLighting) and it does not help. Any suggestions? Can be demonstrated using 3D Models scenario in SandCastle -> https://sandcastle.cesium.com/?src=3D%20Models.html

Example:

At 07:00:00 UTC the model will be way too dark.

At 18:00:00 UTC the model is brighter.

I am defining a realy huge polygon that changes its position and shape using inertial reference frame.

First, I tryed to define a set of CZML polygons, each one with an availability and its coordinates like the "california" object in this sandcastle example, but this exceeds the maximum memory limit and blocks the browser and eventually the computer. Then, I had it working using only one polygon in CZML providing a list with an interval and the polygon shape coordinates, like the "dynamicPolygon" in the same sandcastle example.

Now I am trying to change the CZML implementation to use entities but the entity documentation allows to use a PolygonGraphics that allows to use a Property or a PolygonHierarchy to configure the shape, and I can not figure out how to do the same "dynamicPolygon" using entities.

I am not able to figure out a way to change the material of a polygon entity from a GeoJsonDataSource. I would like to apply an image.

Here is an example using a color because I don't know how to embed an image on the online sandcastle:

There is this question: How to format Visual Studio XML documentation for display on the web, which is similar to what I want. But the answers for this question are all very old and the tools mentioned (sandcastle, docu, NDoc, AutoHelp) are all outdated and not maintained anymore since years.

Is there a modern tool that generates a PDF (or static HTML) from XML doc strings in a .NET project?

I have a dataframe such that...
