Making and connecting hexagons on a rectangle grid

Asked 2022-Apr-16 at 15:16

I am creating a pathfinding application and I want to connect every hexgon(H) to its adjacent hexagons. The grid is a rectangle but it is populated with hexagons. The issue is the code right now to connect these hexagons is lengthy and extremely finicky. An example of what i am trying to achieve is:

The issue is that the connections between say one hexagon and its neighbours (range from 2-6 depending on their placement in the grid) is not working properly. An example of the code i am using right now to connect a hexagon with 6 neighbours is:

Answered 2022-Apr-16 at 15:16

Interesting problem... To set a solid foundation, here's a hexagon grid class that is neither lengthy nor finicky, based on a simple data structure of a linear array. A couple of notes...

The HexagonGrid constructor accepts the hexagon grid dimensions in terms of the number of hexagons wide (hexWidth) by number of hexagons high (hexHeight).
The hexHeight alternates by an additional hexagon every other column for a more pleasing appearance. Thus an odd number for hexWidth bookends the hexagon grid with the same number of hexagons in the first and last columns.
The length attribute represents the total number of hexagons in the grid.
Each hexagon is referenced by a linear index from 0..length.
The hexagonIndex method which takes (x,y) coordinates returns an the linear index based on an approximation of the closest hexagon. Thus, when near the edges of a hexagon, the index returned might be a close neighbor.
Am not totally satisfied with the class structure, but is sufficient to show the key algorithms involved in a linear indexed hexagon grid.

To aid in visualizing the linear indexing scheme, the code snippet displays the linear index value in the hexagon. Such an indexing scheme offers the opportunity to have a parallel array of the same length which represents the characteristics of each specific hexagon by index.

Also exemplified is the ability to translate from mouse coordinates to the hexagon index, by clicking on any hexagon, which will redraw the hexagon with a thicker border.

PCL viewer inside QtCreator widget with VTK and QVTKOpenGLStereoWidget

Asked 2022-Feb-27 at 22:21

I need to make a graphical window with a Qt widget that allows to represent inside it a point cloud that I have previously loaded using the PLC library.

Here's what I have so far that doesn't work (I based it on tutorials and this answer).

I'm using:

Ubuntu 20.04
Qt Creator 5.15
VTK 9.1
PCL 1.12

The reason I am using QVTKOpenGLStereoWidget is that as far as I read both QVTKOpenGLWidget and QVTKWidget are no longer available or will be discontinued in future releases.

mapping colors to amplitude

Asked 2022-Feb-14 at 16:47

I am working on a music visualizer and I am hoping for the colors on the spectrum to gradually change from green to red based on the amplitude. Here are the instructions given:

Change the colour of each bar such that it gradually changes from green to red based on the amplitude value [2 marks]. For example

An amplitude value of 0 the colour values are R:0, G:255 and B:0. An amplitude value of 127 colour values are R:127, G:127 and B:0 An amplitude value of 255 colour values are R:255, G:0 and B: 0

Here is my code:

what you have there are specific points in a function, but you've defined those points for entire ranges. What you should do is write a function that outputs these values in a smooth fashion.

So let's look at your first number, which I assume is the R (red) value. if(spectrum[i] > 200) red = 255; if(spectrum[i] > 100 && spectrum[i] < 200) red = 127; else red = 0; What if instead of outputting single values, you made a function to map the amplitude directly to a Red value? To start with, make it really simple:

Save a PCL specific view as image

Asked 2022-Feb-07 at 13:02

I am new to C++ and the use of the Pointcloud Library PCL (https://pointclouds.org/). At the moment I am able to generate a viewer of the point cloud by using the and I was wondering if it would be possible to save an image of the current viewer "view".

Imagine I have a picture like the following: At the moment I just take a screenshot manually of what it looks like. However, since I will be processing many point clouds, I would like to have a way to convert this "viewer view" to an image.

Answered 2022-Feb-07 at 13:02

Of course I posted the question after researching online. However, I could not find the super easy solution available already in PCL.

You just need to use the function:

void pcl::visualization::PCLVisualizer::saveScreenshot ( const std::string & file )

I hope this will be helpful for someone else in the same situation.

when you use the square brakets you should not put . between them. And you can omit square brakets and use dot syntax only if you have deserialized object, not just parsed it

Deserilizing a list of Json Objects only gives me a string of the object name?

Asked 2022-Feb-04 at 15:52

I have two projects. One is sending a GET request to the other for a List which is equaivalent to a List for the app sending the request.

When debugging, my responseString equals "System.Collections.Generic.List'1" and in the JSON visualizer says String is not JSON formatted. Why isn't my response being passed as JSON?

How can I plot 4 vertexes using a nested loop?

Asked 2022-Jan-30 at 18:40

I'm trying to make a visualizer and I have to draw 4 vertexes while using math to make each vertex so they can react with the music. Rather than just typing all 4 of them out and plotting them I would like to use a nested for loop to do this. I was testing using a regular ellipse with the translate function in p5.js and the translate seems to be translating itself and not just changing the values to how I would want it.

...

ANSWER

Answered 2022-Jan-30 at 18:40

translate does not set a translation, but concatenates the current transformation matrix with the new translation. Therefore you need to push the transformation matrix before appending the new translation and pop the matrix after drawing the geometry:

Call the function pydrake.geometry.MeshcatVisualizerCpp.AddToBuilder to add it to your diagram. When you start your program, it will print a URL to the console where you can open a web browser to view it.

QUESTION

How can I make this particle code run as I want it?

Asked 2022-Jan-17 at 21:26

I'm trying to make a voice recorder visualizer where the shapes would interact with little squares that are being passed from the left to the right of the screen to make it seem like it's recording a voice note. For some reason, I cannot get the squares to space exactly how I want them to, so I decided to push one square out at a time and when that square reaches a certain part on the screen, another square would start from the beginning so they can move at the speed and have the distance between each other I would like.

The problem is when I get the square to reach a certain part on the screen, the other square does not add at all, I tried adding a fill to change the color to see what happens but it just changes the color of the current square and that's it.

Answered 2022-Jan-17 at 21:26

I believe you have fundamentally misunderstood how the rect() function works. The rect() function, and other shape drawing functions in p5.js, do not return a value. All shapes are draw in what is called "immediate mode" which means the shapes are drawn right away and are not persistent objects that can be manipulated. If you want to move a rectangle for example you need to clear the canvas and redraw the rectangle.

Here's is the most sensible adjustment of your sketch that I could come up with:
