ANSWER

Answered 2021-Aug-28 at 15:09

If you don't mind some hack

According to the java doc of PriorityQueue(PriorityQueue)

Creates a PriorityQueue containing the elements in the specified priority queue. This priority queue will be ordered according to the same ordering as the given priority queue.

So we can extend PriorityQueue as CustomComparatorPriorityQueue to hold the desired comparator and the Collection we need to heapify. Then call new PriorityQueue(PriorityQueue) with an instance of CustomComparatorPriorityQueue.

Below is tested to work in Java 15.

How to do N-Point circular convolution for 1D signal with numpy?

Asked 2022-Feb-09 at 20:03

I want a circular convolution function where I can set the number N as I like.

All examples I looked at like here and here assume that full padding is required but that not what I want.

I want to have the result for different values of N

so input would N and and two different arrays of values
the output should be the N point convolved signal

Here is the formula for circular convolution. Sub N can be seen as the modulo operation.

taken from this basic introduction

update for possible solution

This answer is a suitable solution when the array a is piled accordingly to the different cases of N.

When I find time I will post a complete answer, meanwhile feel free to do so.

Thanks to @André pointing this out in the comments!

How to improve the HTML Table Styling that is to be converted into a PDF File

Asked 2022-Jan-25 at 00:43

I have a Python code that is creating HTML Tables and then turning it into a PDF file. This is the output that I am currently getting

This image is taken from PDF File that is being generated as result (and it is zoomed out at 55%)

I want to make this look better. Something similar to this, if I may

This image has 13 columns, I don't want that. I want to keep 5 columns but my major concern is the size of the td in my HTML files. It is too small in width and that is why, the text is also very stacked up in each td. But if you look at the other image, text is much more visible and boxes are much more bigger width wise. Moreover, it doesn't suffer from height problems either (the height of the box is in such a way that it covers the whole of the PDF Page and all the tds don't look like stretched down)

I have tried to play around the height and width of my td in the HTML File, but unfortunately, nothing really seemed to work for me.

Edit: Using the code provided by onkar ruikar, I was able to achieve very good results. However, it created the same problem that I was facing previously. The question was asked here: Horizontally merge and divide cells in an HTML Table for Timetable based on the Data in Python File

What I've done here is remove the borders from the table and collapsed the space for them.

I've then used more semantic elements for both table headings and your actual content with semantic class names. This included adding a new element for the elements you want at the bottom of the cell. Finally, the teacher and codes are floated left and right respectively.

Asked 2022-Jan-15 at 06:02

Please note this question is an extension of this previously asked question: How to make Images/PDF of Timetable using Python

I am working on a program that generates randomized Timetable based on an algorithm. For the Final Output of that program, I require a Timetable to be stored in a PDF File.

There are multiple sections and each section must have its own timetable/schedule. Each Section can have multiple Courses whose lectures will be allocated on different slots from Monday to Friday by the algorithm. For my timetable,

There are 5 days in total (Monday to Friday)
Each day will have 5 slots (0 to 4 in indexes. With a "Lunch" Break between 3rd and 4th slot)

As an Example, I have created below a dictionary where key represents the Section and the items have a 2D Array of size 5x5. Each Index of that 2D array contains the course details for which the lecture will take place in that slot.

I am not much familiar with Jinja, so this answer might not be the most efficient one.

By using basic hard coding in your Template.HTML file, I was able to achieve the results you are trying to. For this, I used the same code that was given by D-E-N in your previous question.

I combined all the attributes of your object into a string

An attribute is differentiated from another with @ (like Course and Teacher)
Instead of using space character, I used a _ character to represent space character in the attributes.
If one slot contains multiple objects, they are differentiated with space character (just like in the code provided by D-E-N)

Here's the updated code of yours with these changes,

QUESTION

Possible ODR-violations when using a constexpr variable in the definition of an inline function (in C++14)

Asked 2022-Jan-12 at 10:38

(Note! This question particularly covers the state of C++14, before the introduction of inline variables in C++17)

TLDR; Question

What constitutes odr-use of a constexpr variable used in the definition of an inline function, such that multiple definitions of the function violates [basic.def.odr]/6?

(... likely [basic.def.odr]/3; but could this silently introduce UB in a program as soon as, say, the address of such a constexpr variable is taken in the context of the inline function's definition?)

TLDR example: does a program where doMath() defined as follows:

...

ANSWER

Answered 2021-Sep-08 at 16:34

In the OP's example with std::max, an ODR violation does indeed occur, and the program is ill-formed NDR. To avoid this issue, you might consider one of the following fixes:

give the doMath function internal linkage, or
move the declaration of kTwo inside doMath

A variable that is used by an expression is considered to be odr-used unless there is a certain kind of simple proof that the reference to the variable can be replaced by the compile-time constant value of the variable without changing the result of the expression. If such a simple proof exists, then the standard requires the compiler perform such a replacement; consequently the variable is not odr-used (in particular, it does not require a definition, and the issue described by the OP would be avoided because none of the translation units in which doMath is defined would actually reference a definition of kTwo). If the expression is too complicated, however, then all bets are off. The compiler might still replace the variable with its value, in which case the program may work as you expect; or the program may exhibit bugs or crash. That's the reality with IFNDR programs.

The case where the variable is immediately passed by reference to a function, with the reference binding directly, is one common case where the variable is used in a way that is too complicated and the compiler is not required to determine whether or not it may be replaced by its compile-time constant value. This is because doing so would necessarily require inspecting the definition of the function (such as std::max in this example).

You can "help" the compiler by writing int(kTwo) and using that as the argument to std::max as opposed to kTwo itself; this prevents an odr-use since the lvalue-to-rvalue conversion is now immediately applied prior to calling the function. I don't think this is a great solution (I recommend one of the two solutions that I previously mentioned) but it has its uses (GoogleTest uses this in order to avoid introducing odr-uses in statements like EXPECT_EQ(2, kTwo)).

If you want to know more about how to understand the precise definition of odr-use, involving "potential results of an expression e...", that would be best addressed with a separate question.

QUESTION

THREE.JS & Reality Capture - Rotation issue photogrammetry reference camera's in a 3D space

Asked 2022-Jan-03 at 14:57

Thanks for taking the time to review my post. I hope that this post will not only yield results for myself but perhaps helps others too!

Introduction

Currently I am working on a project involving pointclouds generated with photogrammetry. It consists of photos combined with laser scans. The software used in making the pointcloud is Reality Capture. Besides the pointcloud export one can export "Internal/External camera parameters" providing the ability of retrieving photos that are used to make up a certain 3D point in the pointcloud. Reality Capture isn't that well documented online and I have also posted in their forum regarding camera variables, perhaps it can be of use in solving the issue at hand?

Only a few variables listed in the camera parameters file are relevant (for now) in referencing camera positioning such as filename, x,y,alt for location, heading, pitch and roll as its rotation.

Currently the generated pointcloud is loaded into the browser compatible THREE.JS viewer after which the camera parameters .csv file is loaded and for each known photo a 'PerspectiveCamera' is spawned with a green cube. An example is shown below:

The challenge

As a matter of fact you might already know what the issue might be based on the previous image (or the title of this post of course ;P) Just in case you might not have spotted it, the direction of the cameras is all wrong. Let me visualize it for you with shabby self-drawn vectors that rudimentary show in what direction it should be facing (Marked in red) and how it is currently vectored (green).

Row 37, DJI_0176.jpg is the most right camera with a red reference line row 38 is 177 etc. The last picture (Row 48 is DJI_189.jpg) and corresponds with the most left image of the clustured images (as I didn't draw the other two camera references within the image above I did not include the others).

When you copy the data below into an Excel sheet it should display correctly ^^

...

ANSWER

Answered 2022-Jan-02 at 22:26

At first glance, I see three possibilities:

It's hard to see where the issue is without showing how you're using the createCamera() method. You could be swapping pitch with heading or something like that. In Three.js, heading is rotation around the Y-axis, pitch around X-axis, and roll around Z-axis.
Secondly, do you know in what order the heading, pitch, roll measurements were taken by your sensor? That will affect the way in which you initiate your THREE.Euler(xRad, yRad, zRad, 'XYZ'), since the order in which to apply rotations could also be 'YZX', 'ZXY', 'XZY', 'YXZ' or 'ZYX'.
Finally, you have to think "What does heading: 0 mean to the sensor?" It could mean different things between real-world and Three.js coordinate system. A camera with no rotation in Three.js is looking straight down towards -Z axis, but your sensor might have it pointing towards +Z, or +X, etc.

Edit:

I added a demo below, I think this is what you needed from the screenshots. Notice I multiplied pitch * -1 so the cameras "Look down", and added +180 to the heading so they're pointing in the right... heading.

Why does the first element outside of a defined array default to zero?

ANSWER

Answered 2021-Dec-13 at 20:55

It does not default to zero. The sample answer is wrong. Undefined behaviour is undefined; the value may be 0, it may be 100. Accessing it may cause a seg fault, or cause your computer to be formatted.

As to why it's not an error, it's because C++ is not required to do bounds checking on arrays. You could use a vector and use the at function, which throws exceptions if you go outside the bounds, but arrays do not.
