## Collision detection between rectangles rotated in javascript

Is there a function that can detect collisions between 2 rectangles rotated in javascript?

``` ```

```rectColl function (rect1, rect2) { //Code back crashing } ```

## Why is Lightroom crushing my rotated photos?

I have occasionally seen an error in which the LR JPEG preview is not synchronized with the actual rotation of an image (used in RAW). Usually, you can rotate the photo and then rotate it backwards, and the problem will be solved.

If that does not solve the problem, then you have found an error in the way a particular camera writes its EXIF ​​tags (or maybe an error in the way the Lightroom application interprets those tags). If so, you must report it to Adobe and hope that it is finally solved.

In the meantime, you can probably use exiftool or some other similar tool to adjust the EXIF ​​image rotation metadata for LR to do the right thing, although I could not tell you exactly what to change from the top of my head without seeing what. Camera tags written in your files (and maybe not even then).

## Equation of rotated surface

I would like to determine the equation of a disk rotated around the z-axis to $$theta$$ angle. Could you tell me how to start?

The equation of the disk is.

$$(y-a) ^ 2 + (z-a) ^ 2 <= r ^ 2$$

Could you tell me how to start the problem?

## screen: horizontal lines appear wavy when scrolling on the IPS monitor rotated

I am connecting an Acer monitor (CB271HU bmidprx 27 "IPS 2K) connected via DisplayPort to my 13 & # 39; & # 39; 2017 MBP (graphics card: Intel Iris Plus Graphics 640 1536 MB) .When I rotate the monitor vertically (rotation of 90 degrees), I notice that the lines do not update at the same speed horizontally.They seem to be wavy when I move up and down.I recorded the screen when I scroll through an image here.It seems that the left half of the rotated screen is delayed behind the right half.

## calculation – Find the volume of a solid rotated around the x-axis

$$y = x ^ 3, y = x, x geq 0$$

begin {align} V & = int_ {0} ^ {1} A (x) dx = int_ {0} ^ {1} pi (xx ^ 3) ^ 2dx = pi int_ {0} ^ {1} (x ^ 2-2x ^ 4 + x ^ 6) dx \ & = pi bigg[ frac{1}{3}x^3 – frac{2}{5}x^5 + frac{1}{7}x^7bigg]0 <1> end {align}

The response of the book says that the answer is $$frac {4 pi} {21}$$ But I'm not getting close to that.

I think there are three main areas in which I checked that I could have ruined, but I do not see anything.
1) configuration
2) integration
3) get the volume

Here is a view of how the graph looks and the area that I am trying to integrate.

## How to verify the collisions between a rotated rectangle and a straight line?

How do I detect collisions between a rotated rectangle and a straight line?

## geometry of the numbers: What lattices can be rotated in your copy to scale?

Leave $$L = { sum_i n_iv_i mid n_i in mathbb Z }$$ be something lattice generated $$d$$ independent vectors $$(v_i) _1 ^ d$$ since $$mathbb R ^ d$$. Call $$L$$ rotary If for some scalar multiple of some orthogonal transformation, $$M$$, we have $$M (L) subset L$$. For example, $$mathbb Z ^ d$$ it is rotating, and that's how it is $${n_1 (1,0) + n_2 (0, sqrt 2) }$$, but $${n_1 (1,0) + n_2 (0, pi) }$$ It is not. I am sure that this is a well-known notion with several equivalent definitions, but I could not find anything, so I would appreciate any suggestions or results about them.

## javascript – Find palindromes on a rotated circular rope

I am trying to face a programming challenge to determine how many palindromes exist in a given string that is being rotated character by character. My solution works, but it's too slow, and I'm struggling to optimize it.

For example, the chain "cacbbba" would rotate 6 times and would have 3 palindromes in each chain.

1. cacbbba (3 palindromes)
3. cbbbaCalifornia (3 palindromes)
4. bbbacac (3 palindromes)
5. bbacacb (3 palindromes)
6. licensed in letterscacbb (3 palindromes)
7. acacbbb (3 palindromes)
``````circular functionPalindromes (s) {
const k = s.length;
result of const = [];
const isPalindrome = (str) => {
const len ​​= str.length;

for (be i = 0; i < len / 2; i++) {
if (str[i] !== str[len - 1 - i]) {
return false;
}
}

return true;
};
const subs = (s) => {
leaves max = 0;

for (be i = 0; i <s.length; i ++) {
for (be j = 1; j <= s.length - i; j ++) {
const sub = s.substring (i, i + j);

if (sub.length < 2) continue;

if (isPalindrome(sub) && sub.length > max) {
max = sub.length;
}
}
}

return max;
};

for (be i = 0; i <k; i ++) {
result.push (subs (s.substring (i, k) + s.substring (0, i)));
}

return result
}
console.log (circularPalindromes (& # 39; cacbbba & # 39;));``````

## java – Program to validate if the matrix is ​​rotated

The program works as planned until it reaches the end. The program is still waiting for the user's input. I'm not completely sure how to fix it. You may have to use system.in.read ()? Anyway, if there is any advice on my code that I can give, it would be very appreciated.

Description:
This program will ask the user for two matrices. The isRotated function
check if the lengths are the same size for the elements. Going to
Then check if the matrix has been rotated by checking the elements of the
original from the first element to the last, while the other matrix will be
Checked from the last element to the first.

For example:

1st array = [1,2,3]
2nd matrix = [3,2,1]

output: the matrix is ​​rotated
