kandi X-RAY | Cesium Summary

Cesium is a C library. Cesium has no bugs, it has no vulnerabilities and it has low support. You can download it from GitHub.

To make, ensure that you have Boehm’s GC and the latest LLVM installed on your machine. You will need to adjust some paths in the makefile and in cs_env. Note that I have Cesium in a directory called cstar2. Simply replace that with whatever directory you have Cesium in. Now just type make.

As I see, the problem here not in the library, but in a way of managing calculation and visualization.

As few people already mentioned, for UI, user don't need more than 60fps, but for process sometimes we need more.

So the solution is to separate processing from visualization.

To be more generic, here is an example in pure JavaScript:

dispatch with UseReducer and useContext hooks: dispatch does not exist on type {}

Asked 2021-May-18 at 22:05

I'm trying to build a small Cesium app with React that can zoom to various places on the globe by clicking a button associated with each location. I'm working on setting up the reducer using the useContext and useReducer hooks, but I'm having an issue with the dispatch that I can't figure out and haven't been able to find anything so far that points to what my issue might be. All the pages I've looked at so far tell me that what I have should work, but I'm obviously missing something.

Here are the two files I'm working with below:

The error you're seeing is caused by createContext not correctly inferring your context's type. You can explicitly specify the context's type like so:

QUESTION

Cesium offscreen rendering with node js?

Asked 2021-Apr-29 at 18:11

I have a web page that renders scenes with Cesium. I also need to encode the same scene to a video stream and send it via UDP encoded with h264. The receiver side can only receive a video stream, no browser can be involved.

I thought of a solution to offscreen rendering to a framebuffer with Cesium and then encode the texture with libav/ffmpeg. But I don't know if it is possible to render with Cesium offscreen without a browser (invoking rendering commands from NodeJS). Is it possible? How can I render the scene to a texture?

I have little to no experience with NodeJS/Cesium.

...

ANSWER

Answered 2021-Apr-29 at 18:11

So, the answer is basically: it can't be done without a browser since CesiumJS uses WebGL and the latter needs a renderer which a browser has.

And it is hardly an option to either mess with Cesium to draw with OpenGL or to use a standalone renderer. However, there are 3 legit options. You can access a renderer:

in Chromium Embedded Framework. It is very hard to use.
QtWebEngine (didn't try though)
Electron.

Electron happened to be a solution.

QUESTION

How to get the index of data in Cesium

Asked 2021-Apr-26 at 18:33

I have successfully implemented the tutorial on how to build a flight tracker. I would like to be able to access the index of my data at a current time in my app. In other words, when cesium is showing the animation of the airplane following the flight path, how can I get the current index that the airplane is at? (the index of my data).

I have two entities, one under a loop to generate all the points of the path and another where I load an airplane model. I need to sync other parts of my app with the current state of Cesium. (If I pause Cesium, I need to pause other things, etc.)

Im using Resium. btw. This is my airplane model. It animates according to the position property which is derived from const positionProperty = new SampledPositionProperty();

...

ANSWER

Answered 2021-Apr-26 at 18:32

You might be looking for SampledPositionProperty.getValue(...).

You have a variable positionProperty that is of type SampledPositionProperty. It's marked const, but I believe this is incorrect, because you're adding samples to it after construction.

In any case, to get data out of there, you want to call something like this:

Change WMS CRS in cesiumJS

Asked 2021-Apr-07 at 11:54

I´m currently working on a project where I need to embed a WMS, which doesn´t support CRS:84 but many EPSG Versions. Here is the link to the WMS, which I need to include (the service is not controlled from our side).

I´ve already changed the crs parameter of the WebMapServiceImageryProvider to EPSG:4326, but that doesn´t adjust the bbox parameter to the correct values.

I hope that someone could help me to change the CRS in my cesium project.

I´m happy for any help.

Create Cesium.Ray from Cesium.Cartesian3 and Cesium.HeadingPitchRoll

Asked 2021-Mar-27 at 23:54

Is it possible to create a Cesium.Ray from a Cesium.Cartesian3 and a Cesium.HeadingPitchRoll?

If so, how would one go about this?

...

ANSWER

Answered 2021-Mar-27 at 23:54

Yes, it is possible. These two kinds of objects hold different kinds of information, so be careful that you're not losing data in the conversion.

A Ray has an origin (Cartesian position) and a direction which is just a unit vector, not the same as a full orientation.
The HeadingPitchRoll is a full orientation. The Heading and Pitch work together to identify a particular "forward" direction, and Roll indicates a rotation about that direction vector. This Roll rotation does not affect the direction, and so will not have an effect on a Ray.

Here's the code:

How to keep Models in Cesium bright all time

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.
