QUESTION
I got this error: Uncaught TypeError: Class constructor Object3D cannot be invoked without 'new' at new THREE.CSS2DObject and i try to run this project: https://github.com/vasturiano/3d-force-graph/blob/master/example/text-nodes/index.html
...ANSWER
Answered 2021-Jun-20 at 08:19This error indicates that THREE.CSS2DObject
and the core library three.js
are from different releases. Such setup are not supported and should always be avoided.
Notice that lately the code base was migrated to ES6 classes. If you try to derive from an ES6 class with ES5 prototype style code, you will encounter the above runtime error. So it seems the code use a newer three.js
than THREE.CSS2DObject
.
QUESTION
I only know javascript from a web browser perspective but I need to display data online in the way this web component does: https://github.com/vasturiano/3d-force-graph
The thing is that the setup instructions there aren't newbies friendly at all. It assumes some basic to advanced knowledge. So I made some research and even though everyone talking about the component say it's very easy to implement, none of them say how.
I kind of presume that there must be some javascript server involved (node.js ?). That Three.js and d3-force-3d must be imported (somehow, somewhere). But that's it. I'm not even sure it's enough. But I just can't figure out how to setup the whole thing so that I can run one of those scripts.
So, can anyone just give me hints, at a newbie level, so that I can work my way through using those scripts? Because at this point, I'm willing to search but I don't know what to search for exactly. I'm lacking the big picture while the info in the link are very particular and not very thorough.
I searched the web for two days but there is not much to find about 3d-force-graph and there is zero info on how to set it up.
All I need is a bridge in terms of info, so that these scripts can be set up and run (with custom data) by a non expert. I mean what environment, what libraries/dependencies, what to import, how to import, etc. Not necessarily in details as any help would be a good starting point.
Thank you.

Answered 2021-Jun-04 at 16:01I was able to run the basic example by simply creating an .html file and putting it in a web server. So if you grab the Basic example (https://github.com/vasturiano/3d-force-graph/blob/master/example/basic/index.html) and get that file content into your development web server.
So the index.html
file would look like:
QUESTION
I see this related solution D3js Force Directed Graph Link not found
yet I get the error in the title - "VM2128 d3-force-3d:2 Uncaught Error: node not found: golfing_4_1"
...ANSWER
Answered 2020-Nov-17 at 09:13The underlying problem was that you needed to pass the entire graphData
to your d3.forceLink
function, not just graphData.link
. However, I think the following solution is cleaner:
From the documentation of 3d-force-graph
for Graph.d3Force()
:
Getter/setter for the internal forces that control the d3 simulation engine. Follows the same interface as d3-force-3d's simulation.force. Three forces are included by default: 'link' (based on forceLink), 'charge' (based on forceManyBody) and 'center' (based on forceCenter).
This means that you can call the function with only a string 'link'
and you get an object of type d3-force-3d.forceLink
, which is automatically applied and thus automatically has access to the right graphData
. Then, you can set forceLink.id
just like you did, but you can also set it later.
QUESTION
I'm making an application where a viewer can use a dat.gui menu to update their Three.js animation. Specifically, I'm using 3d-force-graph.
When the users makes a change, I do the following:
- swap the old .json runnning their animation with the new one required to render their choice
- run a function called
vertexControl
which changes the nodes of their new animation (e.g., color change).
Simple example:
...ANSWER
Answered 2020-Oct-17 at 00:35The problem is that Graph.jsonUrl()
has to load that JSON asynchronously, but vertexControl()
is performed immediately, before the JSON has finished loading. I'm looking at the force-graph docs, and sadly there is no built-in way to perform a callback for when the JSON finishes loading. You might have to load the JSON yourself with THREE.FileLoader
so you can invoke your own callback after loading is complete:
QUESTION
I have this react app I want to dockerize. But the problem is, even though I tried, it doesn't work. But it works pretty well locally
This is how the current directories look like:
...ANSWER
Answered 2020-Sep-18 at 09:09Firstly, make sure you are copying the same package-lock.json file that you use to install deps locally, to make sure you have the same dependency tree in your container as you do locally.
COPY package.json package-lock.json /app/
Then, make sure that you are matching the same node/npm version as you run locally (replace 12 with the major version you are running, be it 10, 12, 14 or whatever):
FROM node:12
Each node version is bundled with a specific npm version (latest 12 version comes with npm 6.14.6), you can find the bundled NPM version int he changelogs, https://github.com/nodejs/node/tree/master/doc/changelogs
Additionally, instead of running npm install
, you might wanna run npm ci
in the container. The latter skips any checks for discrepancy between the lock file and your package.json file and just installs the locked dependency tree, which is not only faster, but will also match your local dep tree exactly.
EDIT:
In addition, this line:
COPY . /app
Would also overwrite node_modules unless you have ignored it via .dockerignore or similar.
Easiest would probably be to add a .dockerignore
file to the same folder as your Dockerfile and add lines stating:
QUESTION
I am working on a 3D force-graph visualisation and I'm using the great library:
https://github.com/vasturiano/3d-force-graph
I would like to try to get some sort of glowing effect on the nodes of the force-graph and I was having a look at something like this to accomplish it, but it is proving a challenge:
https://github.com/jeromeetienne/threex.geometricglow
So far I only have the ability to add new shapes and texture them. I have also added text sprites that follow the nodes, so I suspect an approach that combines these two might be possible. See below the code.
Adding a glow effect or texture to this base code would also be very helpful:
https://github.com/vasturiano/3d-force-graph/blob/master/example/async-load/index.html
...ANSWER
Answered 2020-Feb-11 at 16:52I've been interested in getting this to work as well.
I used this threex example and seen that these two lines were necessary:
