camera-control | Change camera FOV | Camera library

I'm trying to useState in my MERN project, and I have defaultSize defined in MongoDB, and am trying to useState by product.defaultSize. If I change some of my code (like adding console.log("hello")) and save it, the error disapears and loads fine. But if I refresh the page the error comes back?

Google's provides all the key features I need without having write a custom solution via something like react-three-fiber or directly in three.js.

I am struggling with how to properly integrate it into a Reagent (and React for that matter) structure.

In order to make it easy to use with vanilla JS, is built as a web component and is largely controlled via the attributes on its html element. Normally that wouldn't be much of a problem, but with the overhead of 3D and loading large models re-rendering this is expensive and in many cases functionality-breaking.

I've tried to naively use it inside a component and trying to eliminate the possibility of re-rendering. Using a ref to mutate it directly.

I have also tried setting it up as a manually created html element from the Reagent/React controlled application and reference it in various events via its dom element.

Both of these options introduced a lot of hacks and were not ideal in a single page application.

I am wondering if anyone has any tips on how to best wrap this in a React/Reagent shell, while still having access to the core element to use their underlying JS api.

Answers don't have to be in ClojureScript.

Here is the example of its usage from their page:

Using model-viewer (https://modelviewer.dev/examples/loading/index.html#glbModel) I want to give loading color of my model-viewer as red but I did not find anything related to that in the documentation.

I'm trying to create a viewer in react-three-fiber with react-three/drei where I can switch between OrbitControls and TrackballControls. The problem is that when switching from TrackballControls to OrbitControls, the axis that the camera rotates around changes as of course the TrackballControls change the up-vector when moving around.

I created a couple of minimal examples in codesandbox to explain my approach to solve this and to show where I'm stuck.

This shows the initial attempt to switch between the different control types:

Obviously, this does not work as it is, so I tried resetting the up-vector to (0, 1, 0) and calling lookAt(). This seems to work initially as the camera reorients itself correctly (this is how it should look like). However, it does not rotate around the correct axis and instead moves in strange arcs. See here:
https://codesandbox.io/s/r3f-camera-controllers-set-up-vector-yps4k

For this question it was suggested to create a new camera which I also tried but ultimately it lead to the same result. This here is my attempt at creating a new camera and copying some values to the new camera:

Any help appreciated. Thanks!

I've got some dynamic buttons that are a child component, and get assigned a value="URL" based off of my MongoDB. How do I go about passing that generated value to my parent/web component src={currentSrc}? When I assign it, it says that currentSrc is not defined?

Here's the SizeOptions:

I made a static webpage app that I have been slowly converting to React (MERN stack) to make it more dynamic/so I won't have to configure each and every HTML document. It's a product configurator that uses Google's model-viewer.

I'm fairly new to using a full-stack workflow but have found it pretty fun so far! I am having trouble however understanding on how to convert some of my vanilla JS to work within React. This particular script will change a source/3D model when a user clicks on a button. Below is a code snipit of what I have working currently on a static webpage.

I am trying to use Google's model viewer to load 3D models. It has a button. But I want that button to be visible after the model is completely loaded. So, I used to use this Vanilla JavaScript code

In a 3D Plotly plot the camera center defaults to (0,0,0), where, as far as I understand, (0,0,0) refers to the centre of the 3D volume occupied by the plot, not the coordinate (0,0,0).

These values can be changed via layout.scene.camera.center as documented here and here. However, I can't work out what units are being used, nor can I find this information in the documentation.

E.g. if I change the camera center to (1,1,1), where is this in relation to my plot? From a bit of experimenting I have discovered that:

• (1,1,1) puts the camera center outside the volume occupied by my plot, but I can't figure out how far outside,
• (0.5, 0.5, 0.5) put the camera center near, but not exactly on, one of the edges of the volume occupied by the plot; sometimes it is near a corner of the volume, sometimes it is along an edge.

I have a Tomcat running a JavaWebApplication within I want to use the element (info here) to display a 3D model with 'changable' textures. Therefore I want to get the necessary gltf file from a Servlet, so I can take impact on it, rather than just accessing a file. I know, that both (the gltf structure as well as the model-viewer in my webapp) work, as it works flawlessly if i refer the src like this:
