I want to render a three-dimensional cube with images on its six surfaces in React Native, that can be rotated by the user. First, I wanted to use react-native-canvas, but 3D rendering isn't possible within such a canvas.
My second idea was a Web View, that is shown in React Native and that renders the cube. The big disadvantage of this solution is, that a internet connection is necessary. Furthermore, maybe the performance isn't that good this way.
So, do you have any idea how to solve my problem? Thanks for all responds.
I would recommend you use a javascript framework called three.js. it is designed to do exactly what you are looking for.

First and most important: I am by no means a developer. We hired an agency to develop an APP for us, and i was given by a developed solution that i am not convinced if it is the best solution, So i would like to ask you guysfor advice.
Unfortunatelly i cannot put pictures nor links to code for the app, but i will do my best to explain myself:
The problems i encountered are mainly two:
All items appear to have fixed sizes applyed to them: When testing the app on different devices, the size of the elements is not responsive at all. In fact on small devices (Moto G5) There are elements that fall behind the bottom navigation bar making them unaccessible.
Lot of stuff fall below that said bottom navigation bar.
My question is the following:
Is react native responsive?
In web development there is a lot of flexibility when it comes to responsiveness with CSS and JS. Is React native any different? or there is a way to prepare the layout so it fits most of the common sizes without losing acces to interactions?
Hope i explained myself correctly. and again, sorry for not asking a technical specific question.
React Native is designed to be responsive, but it requires a different approach compared to web development. In web development, you can use CSS and JavaScript to make your website responsive, but in React Native, you use a different set of tools.
We have many ways to make the app responsive with the device's large screen and small screen.
Use the Dimensions API: React Native provides the Dimensions API, which allows you to get the dimensions of the screen at runtime. You can use this information to adjust the layout of your app based on the size of the screen.
Use third-party libraries ex: react-native-size-matters, react-native-responsive-screen, ...
Use Flexbox: React Native uses Flexbox for layout, just like web development. Flexbox is a powerful tool for creating responsive layouts that adapt to different screen sizes. You can use the flex property to adjust the size and position of elements on the screen.
In terms of your specific issue with elements falling behind the bottom navigation bar, it's likely that the layout is not taking the height of the navigation bar into account. You can use the Dimensions API to get the height of the navigation bar and adjust the layout accordingly.
Is there any React native package to create funnel chart like in this?
or how to implement this chart on our own in react-native?
When it comes to drawing lines, shapes, gradients, etc, you have about two decent options in the react-native space.
The first one is React Native Art, the second one is react-native-svg. There are some charting libraries available as well, but when you want full customisation and styling/design options, the best way probably is to stay as close to the drawing api's as possible.
The funnel-graph-js project you mention uses browser SVG to draw the funnel chart, so I guess you can probably copy and adjust some code to achieve a similar result using react-native-svg.
I want to display several components (maybe up to 6) in my React Native app that continuously change their position, i.e. slowly but fluently float on the screen and change their moving direction randomly or based on an angle at which they approach the edge of their parent, if they do. What I don't know is how to change their position dynamically in a performance friendly way. Because I also want to let the user interact with them by tapping on them, it cannot be a video in a background or something similar.
If I were dealing with a standard React app running in a browser, I think I would simply manipulate the element's style attributes top and left. Since I want to implement this in React Native, I think there must be a solution that is way more performant and elegant, involving manipulation of the native elements that back the React Native views or using some animation mechanism, because re-rendering a view with like 6 components at least 30 times per second doesn't seem like an appropriate solution and an overhead in general.
Googling things like "react native dynamically move element" or "react native dynamically change element position" did not bring any obviously appropriate results. I came across a native element method setNativeProps, though, but couldn't find any information on what props I could set to change the element's position on the screen and how performant that would be. I also looked into React Native's Animated API, but could not quite relate my problem to the solutions that this API offers from a first glance.
Does anyone know a mechanism or maybe a library that would be appropriate to use in the situation that I described?
how can I easily create an app like this in React Native?
As you can see on the gif I need to draw rectangles on the grid. Are there any libraries or maybe even paid commercials solutions for creating apps with advanced drawing like this shown on the gif?
Have you seen this library? You might need to flicker something to meet your exact requirement

I have a question and I need to know if we can apply a morphing effect on a photograph in react native. If we can, can you help me to know how we do it and if we cannot what languages is more adapted for a mobile application?
So in fact I have to make a mobile application that allows me:
To Take or choose pictures.
To Define reference points between the two images.
To Calculate the corresponding animation.
And to Save the animation in a video or gif format.
I have already realized the classes that allows me to take a picture and to access at the gallery. (in react-native)
Without more details is hard to answer but you could try react-native-svg. Here is a link to an example Building React Native Animated Feedback UI
or reactArt Morphing SVG Paths with React Art
It would help if, when you ask, you gave more information though (e.g., the image format, what you have already tried, and research you have already conducted to look into the topic.)
Cheers!
