tilt | Android example : Use sensors

I am pretty new to using openCV and this might be a silly question.

I will talk in reference to the picture above. So my problem statement is to draw bounding boxes around all the text elements. Conveniently I can get that information from the json file of the image. So I can get x, y, w and h from json and use cv2.rectangle(img1, (x, y), (x + w, y + h), (255, 255, 255), 2)

The issues is in the json file, for rotated text, it just provides the rotation angle and not the co-ordinates for the rotated rectangle. For example from the image above, for 'yourwebsite.com', x, y, w and h is given and rotation is -90 degrees. I did some basic w, h = h, w to get the bounding box for that. But what should I do when the degrees is like 60 ro 80. Is there any function or method to get the coordinates of rotated bounding boxes?

Example:

In this case the flash sale is tilted at an angle of -22 degrees. But the x, y, w and h is provided for the white rectangle on top not covering anything. It needs to be tilted by a particular angle as mentioned in the json file to be over the FLASH SALE area. x and y always represents the top left corner of the bounding box.

Thank you in advance!

I am using Transform to have a 3D movement on a card. with onPanUpdate it moves all way until it tilts completely. How can I restrict or control the movement in a way that it goes half way at most when you touch any point close to the edges. Here is how I applied Transform:

In my application, I have two components communicating with each other with BehaviorSubject since they are siblings. I have a form and a card, card can be either "question" or " answer" and its color changes accordingly.

To change it I use CSS variables. But I also want a "tilting" animation whenever the color changes. I can't use angular animation because the animation is not data-binded related and in my application, the card component is nested inside various components that are animated with "angular animation" and it's not working anyway.

What I try to do is to bind a class with animation to my card main div but it only triggers when the component loads. What is the correct way to make my card tilt whenever its color changes?

Here is a stackblitz that describes my issue.

This is the error I am getting(can someone please also explain to me why such errors are occurring and if there is a way to update the npm to the version of react I have.):

I'm using the Ursina engine to create a 3D game. However, when i try to load the FirstPersonCharacter, all I got is a grey background (normal) and a very small magenta square, in the center, tilted at 45°. What is that ?

I was first trying to make my own mechanics for a first person character, move the camera according to the mouse position (I have this), and I was playing with math and stuff for movements... I was looking at this video (https://www.youtube.com/watch?v=DHSRaVeQxIk) for totally something else, and I found out about the FirstPersonController.

But, with the (almost) same code as him, it doesn't work ! What's that issue, has someone already ran into it ? Is FirstPersonController broken ? Or is my brain broken ?

Edit : found out in the ursina cheatsheet that the small magenta tilted square is the cursor. But I still can't move, can't have gravity or anything ? And I can't see my floor.

Second edit : using some piece of code the ursina cheatsheet provided, arranged, I can now see my floor. But I can only move the camera on 1 axis (up and down), I can't move, no gravity, nothing...

Here is my code :

Im running ruby version 2.6.1 with docker. Rake gem is version 13.0.1.
Whenever I tried docker-compose up, it always fails and throws this error everytime:
This error did not exist before.

So, I found a video of Tech with Tim, where he was creating a flappy bird py file.. Well, my issue is the pygame window in not popping up after running it. I'm using ubuntu 20.04.. Searched for solutions, and mixed all I've learnt since I'm a complete beginner in pygame.. need help :(

I want to achieve the effect same as the attached image. How can I place a view at certain angle? I tried using UIBezierPath with no success.

I have something like follows: Input x, y and h to get pan and tilt orientation
