kandi X-RAY | wave REVIEW AND RATINGS

The Apache Wave project is a stand alone wave server and rich web client that serves as a Wave reference implementation. Apache Wave site: http://incubator.apache.org/wave/ This project lets developers and enterprise users run wave servers and host waves on their own hardware. And then share those waves with other wave servers.

Radial Waves in Processing

float waveOffset = 2*(atan2(y - tiles/2, x - tiles/2));
float sin = sin((frameCount/20.0 + waveOffset));
-----------------------
void setup() {
  size(600, 600);
}

void draw () {
  background(255);
  float tiles = 60;
  float tileSize = width/tiles;
  for (int x = 0; x < tiles; x++) {
    for (int y = 0; y < tiles; y++) {
      float waveOffset = atan2(y - tiles/2, x - tiles/2)*0.5;      
      float sin = sin((frameCount*0.05 + waveOffset));
      float wave = map(sin, -1, 1, 0, tileSize);
      fill(0);
      noStroke();
      pushMatrix();
      translate(tileSize/2, tileSize/2);
      ellipse(x*tileSize, y*tileSize, wave, wave);
      popMatrix();
    }

QUESTION

Convert ckeditor Data to html

Asked 2021-Jun-15 at 14:37

I'm building a vue app where user input data that I store in mongo database. One of the form elements is a ckeditor. When the user inputs data everything works fine.
Now the problem is when I make an API call to get the ckeditor text that user did input, I receive plein string text that I can't convert to html element.

Here's my code

<script>
export default {
  data() {
    return {
      courrierId: this.$route.params.detail,
      courrier: '',
    }
  },
  // i receive the full courrier object without a problem
  async created() {
    const courrier = await axios
      .post(`${baseUrl}getCourrierDetails/${this.courrierId}`)
      .then((response) => {
        this.courrier = response.data[0]
        console.log(response.data)
        return response.data
      })
      .catch((error) => ({ error: JSON.stringify(error) }))
  },
}
</script>

Here's the courrier object I do receive from the DB

enter image description here

What I want to do, is to display the data in the frontend. Everything works fine except for the Text. Here's the code

<div class="text-muted">
 <h5 class="font-size-16 mb-3">Pour</h5>
  <p class="mb-1">
    Nom : <strong>{{ this.courrier.Nom }}</strong>
  </p>
  <p class="mb-1">
    Prénom : <strong>{{ this.courrier.Prénom }}</strong>
  </p>
  <p class="mb-1">
    Alger le : <strong>{{ this.courrier.Date }}</strong>
  </p>
  <p class="mb-1">
    Age : <strong>{{ this.courrier.Age }}</strong>
  </p>
</div>

<h5 class="text-center">
  {{ this.courrier.Type }}
</h5>
{{ this.courrier.Text}}  <!-- this is where the problem reside -->
<div class="d-print-none mt-4">
 <div class="float-end">
     <a href="javascript:window.print()" class="btn btn-success waves-effect waves-light mr-1">

You can use the v-html directive to output real HTML:

<span v-html="this.courrier.Text"></span>

But, It's really not safe. you should refer to vue's documentation at https://vuejs.org/v2/guide/syntax.html#Raw-HTML

QUESTION

WCAG 2.1 compatibility with shinydashboard app form label

Asked 2021-Jun-15 at 03:54

I developed an app using rshiny, https://smandape.shinyapps.io/mmdit/. I am trying to make it WCAG 2.1 accessible. I am using WAVE (Web accessibility evaluation tool) to check for accessibility. Currently, the errors popping are related to 'missing form label'. These errors are specifically for the code fileInput or rabiobuttons (5 errors are on Data import tab). For example, around the following code. WAVE shows the error for the placeholder for fileInput.

fileInput("ss_ID",
   label = "Upload one or more single source data",
   multiple = TRUE,
   accept = "text/plain")

I am not sure what / how in the rshiny code this should be fixed.

ANSWER

Answered 2021-Jun-15 at 03:54

fileInput accessibility was one of the things changed in the Shiny v1.6 release: https://shiny.rstudio.com/reference/shiny/1.6.0/upgrade.html

Closed #2929: Fixed keyboard accessibility for file picker button: keyboard users can now tab to focus on fileInput() widget. (#2937)

Are you definitely using v1.6? It looks like you are, so you may have identified a bug in the shiny framework.

EDIT: I had a look at the code for the fileInput control, and it looks to me like the input and label elements aren't properly linked together. I reported it as an issue: https://github.com/rstudio/shiny/issues/3426

QUESTION

Radial Waves in Processing

Asked 2021-Jun-14 at 18:00

I am currently a bit stuck! Lets say, have a grid of shapes (nested For-Loop) and I want to use a wave to animate it. The wave should have an offset. So far, i can achieve it. Currently the offset affects the Y-axis … But how can I manage to have a RADIAL offset – you know – like the clock hand, or a radar line… I really would like the offset to start from (width/2, height/2) – and then walks around clockwise. Here is my code and the point where I am stuck:

void setup() {
  size(600, 600);
}

void draw () {
  background(255);
  float tiles = 60;
  float tileSize = width/tiles;
  for (int x = 0; x < tiles; x++) {
    for (int y = 0; y < tiles; y++) {
      float waveOffset = map(y, 0, 60, 0, 300);      
      float sin = sin(radians(frameCount + waveOffset));
      float wave = map(sin, -1, 1, 0, tileSize);
      fill(0);
      noStroke();
      pushMatrix();
      translate(tileSize/2, tileSize/2);
      ellipse(x*tileSize, y*tileSize, wave, wave);
      popMatrix();
    }
  }
}

I tried different things – like the rotate(); function etc. but I can't manage to combine it! Thank you for any kind of help!

ANSWER

Answered 2021-Jun-14 at 18:00

Right now, you're defining the size of the ellipses based on a transformation of sin(y). A transformation means it looks like a * sin(b * y + c) + d, and in this case you have

  • a = tileSize / 2
  • b = 300 / 60 = 5
  • c = frameCount
  • d = tileSize / 2

If you want to do a different pattern, you need to use a transformation of sin(theta) where theta is the "angle" of the dot (I put "angle" in quotes because it's really the angle from the vector from the center to the dot and some reference vector).

I suggest using the atan2() function.

Solution:

float waveOffset = 2*(atan2(y - tiles/2, x - tiles/2));
float sin = sin((frameCount/20.0 + waveOffset));

QUESTION

How can I make the C++ compiler support template for STL?

Asked 2021-Jun-10 at 11:42

I am trying to install hpctoolkit using Spack. In order to do that, I executed :

git clone https://github.com/spack/spack.git
cd spack/share/spack
source setup-env.sh 
spack fetch -D hpctoolkit
spack install hpctoolkit 

I can't execute the last command because I get the following error:

Error: ProcessError: Command exited with status 1:
    './bootstrap.sh' '--prefix=/home/hakim/spack/opt/spack/linux-ubuntu20.04-haswell/gcc-10.2.0/boost-1.76.0-oc2u6jxritfsbci4xkhr5lov3i4o4riq' '--with-toolset=gcc' '--with-libraries=serialization,atomic,log,exception,regex,math,random,program_options,wave,iostreams,chrono,system,test,graph,locale,timer,filesystem,date_time,thread' '--without-icu'

It recommended me to take a look at build log by displaying the following message:

See build log for details:
  /tmp/hakim/spack-stage/spack-stage-boost-1.76.0-oc2u6jxritfsbci4xkhr5lov3i4o4riq/spack-build-out.txt

and the previous file contains:

A C++11 capable compiler is required for building the B2 engine.
Toolset 'gcc' does not appear to support C++11.

> g++ -x c++ -std=c++11  check_cxx11.cpp
ERROR: Compiler 'gcc@9.3.0' does not support compiling C++ programs.

In order to display the compilers, I used the command:

spack compiler list 

and the result is:

==> Available compilers
-- clang ubuntu20.04-x86_64 -------------------------------------
clang@10.0.0  clang@7.0.1

-- gcc ubuntu20.04-x86_64 ---------------------------------------
gcc@9.3.0  gcc@7.5.0

In order to get rid of the version 'gcc@9.3.0', I modified compilers.yaml which is a separate file to store information about available compilers.

In my case, I did:

cd ~/.spack/linux
emacs compilers.yaml & 

and found (I'm displaying only the part related to the gcc compiler):

compilers:
- compiler:
        spec: gcc@7.5.0
        paths:

    operating_system: ubuntu20.04
    target: x86_64
    modules: []
    environment: {}
    extra_rpaths: []

In order to get rid of gcc@9.3.0, I just deleted its part. I verify now the list of compilers and I should find:

-- clang ubuntu20.04-x86_64 -------------------------------------
clang@10.0.0  clang@7.0.1

-- gcc ubuntu20.04-x86_64 ---------------------------------------
gcc@7.5.0

And now, when I execute the command:

spack install hpctoolkit 

the error is different. I get :

=> Error: CompilerAccessError: Compiler 'gcc@7.5.0' has executables that are missing or are not executable: ['/usr/bin/gfortran-7', '/usr/bin/gfortran-7']

I think the gcc@7.5.0 compiler has been wrongly installed since he tells me that it has executables that are missing or are not executable.

I tried with gcc@7.5.0, gcc@9.3.0 and gcc@10.2.0 but in vain .. (I want to mention that all the compilers are installed in /usr/bin)

Any help, please ?

In order to fix this error, you should precise the path to g++. In my case, here is the updated content of my compilers.yaml file:

compilers:
- compiler:
        spec: gcc@7.5.0
        paths:
          cc: /usr/bin/gcc-7
          cxx: null
          f77: /usr/bin/gfortran-7
          fc: /usr/bin/gfortran-7
        flags: {}
        operating_system: ubuntu20.04
        target: x86_64
        modules: []
        environment: {}
        extra_rpaths: []

- compiler:
    spec: gcc@9.3.0
    paths:
      cc: /usr/bin/gcc-9
      cxx: /usr/bin/g++-9
      f77: /usr/bin/gfortran-9

    flags: {}
    operating_system: ubuntu20.04
    target: x86_64
    modules: []
    environment: {}
    extra_rpaths: []

Now, it should work perfectly.

While reading a little bit the Spack notation, I learned that ’@’ specifies the package version so I guess that the version of gcc I'm using does not support compiling C++ programs.

How should I do to make it support compiling C++ programs ? Any help, please ?

Answered 2021-Jun-09 at 12:34

As you can see in the error, compiler 'gcc@10.2.0' does not support compiling C++ programs.

In order to display the compilers, use the command:

spack compiler list 

Before retiring the misleading version, I had the following result for the previous command:

-- clang ubuntu20.04-x86_64 -------------------------------------
clang@10.0.0  clang@7.0.1

-- gcc ubuntu20.04-x86_64 ---------------------------------------
gcc@9.3.0    gcc@10.2.0

In order to get rid of the version 'gcc@10.2.0', I modified compilers.yaml which is a separate file to store information about available compilers. This file is normally in your home directory at ~/.spack/platform where ‘platform’ is normally ‘linux’ (or else ‘cray’ or ‘bgq’).

In my case, I did:

cd ~/.spack/linux
emacs compilers.yaml & 

and found (I'm displaying only the part related to the gcc compiler):

    compilers:
    - compiler:
            spec: gcc@10.2.0
            paths:
              cc: /usr/bin/gcc-10
              cxx: null
              f77: /usr/bin/gfortran-10
              fc: /usr/bin/gfortran-10
            flags: {}
            operating_system: ubuntu20.04
            target: x86_64
            modules: []
            environment: {}
            extra_rpaths: []

    - compiler:
        spec: gcc@9.3.0
        paths:
          cc: /usr/bin/gcc-9
          cxx: null
          f77: /usr/bin/gfortran-9
          fc: /usr/bin/gfortran-9
        flags: {}
        operating_system: ubuntu20.04
        target: x86_64
        modules: []
        environment: {}
        extra_rpaths: []

In order to get rid of gcc@10.2.0, just delete its part. Verify now the list of compilers and you should find:

-- clang ubuntu20.04-x86_64 -------------------------------------
clang@10.0.0  clang@7.0.1

-- gcc ubuntu20.04-x86_64 ---------------------------------------
gcc@9.3.0

Last step:

spack install hpctoolkit 

Now, Everything is OK.

IDirectMusicPerformance8 - MIDI only, or WAV?

Asked 2021-Jun-07 at 19:14

I'm trying to work with an old version of DirectX (8.1) and I'm finding the documentation more than a little confusing. It feels like the IDirectMusicPerformance8 interface is for MIDI playback, as it has various MIDI-related methods on it, but various parts of the documentation suggest that it can be used to play back WAV data as well. For instance, the tutorial says that you call InitAudio on the performance, and it states "Wave files require only a single performance channel, and MIDI files require up to 16".

So is it for MIDI or can it be used for WAV?

If it can be used for WAV, I'm even more stumped, because I'm initializing it, running performance->PlaySegment(segment, 0, 0, NULL), getting a success response, but the audio is silent.

ANSWER

Answered 2021-Jun-07 at 19:14

OK, I figured it out. Apparently I had been using IDirectMusicPerformance instead of IDirectMusicPerformance8, which I guess is some kind of old compatibility thing that is missing various new DirectX 8.1 methods. Once I switched to that (along with the associated '8' versions of the loader and segment interfaces), used their new InitAudio and LoadObjectFromFile methods, called segment->Download(performance) before playing, then played with the new PlaySegmentEx method, it worked and played the WAV.

Generating and drawing sin wave using pygame

Asked 2021-Jun-07 at 16:28

I am trying to generate and draw a sin waves. I am using this formulae that I found online y = Amp * sin(2 * PI * frequency * time + shift)

import pygame

window = pygame.display.set_mode((600, 600))

class Point:
    def __init__(self):
        self.x = 0
        self.y = 0

class Line:
    def __init__(self):
        self.points = []

def generateLine(startX, nPoints, length, y):
    line = Line()
    for i in range(nPoints):
        p = Point()
        p.x = startX + ((i / nPoints) * length)
        p.y = y
        line.points.append(p)
    return line;

nPoints = 100
line = generateLine(10, nPoints, 590, 300)
start = time.time()
accNPoints = 0
frequency = 100
amplitude = 30
overallY = 300

while True:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            pygame.quit()

    window.fill((255, 255, 255))

    keys = pygame.key.get_pressed()
    
    if (keys[pygame.K_a]): frequency -= 0.002
    if (keys[pygame.K_d]): frequency += 0.002

    if (keys[pygame.K_s]): amplitude -= 0.05

    if (keys[pygame.K_p]): accNPoints += 0.5
    if (keys[pygame.K_o]): accNPoints -= 0.5

    if accNPoints > 50:
        line = generateLine(10, nPoints, 590, 300)
        accNPoints = 0
        nPoints += 1
    elif accNPoints < -50:
        line = generateLine(10, nPoints, 590, 300)
        accNPoints = 0
        nPoints -= 1

    for i in range(1, len(line.points)):
        #calculate y based on x
        #y = A * sin(2 * PI * f * t + shift)
        #yStart = (amplitude * math.sin(2 * math.pi * frequency * ((time.time() - start) * 0.01) + line.points[i].x))     + overallY
        #yEnd =   (amplitude * math.sin(2 * math.pi * frequency * ((time.time() - start) * 0.01) + line.points[i - 1].x)) + overallY
        yStart = (amplitude * math.sin(2 * math.pi * frequency + line.points[i].x))     + overallY
        yEnd =   (amplitude * math.sin(2 * math.pi * frequency + line.points[i - 1].x)) + overallY

        
        pygame.draw.circle(window, (255, 0, 0), (line.points[i].x, yStart), 1)

            (line.points[i - 1].x, yEnd)
            )

    
    pygame.display.flip()

There seems to be two problems. Changing frequency value does not really seem to change the frequency of the wave. Frequency seems to be dependent on the nPoints variable which is in the function that generates line i.e. def generateLine(startX, nPoints, length, y):.

ANSWER

Answered 2021-Jun-07 at 16:28

The formula is wrong. The x-coordinate depends on the control variable of the loop (i). The y-coordinate needs to depend on the x-coordinate:

e.g.: Frequency 5 (5 waves)

frequency = 5
amplitude = 50
overallY = 300

while True:
    # [...]

    no_pts = window.get_width()
    for i in range(no_pts):
        x = i/no_pts * 2 * math.pi
        y = (amplitude * math.cos(x * frequency)) + overallY
        if i > 0:
            pygame.draw.aaline(window, (0, 0, 0),  prev_pt, (i, y))
        prev_pt = (i, y)

QUESTION

React inlined SVG paths are not responding to css animations

Asked 2021-Jun-06 at 13:31

I uploaded my code and svgs to this github repo.

I have some svgs of some circles, blobs and triangles. I am trying to make the circles shake, like how the guy shakes in this code pen when you hover on him, I am trying to make the blobs move like waves like in this code pen, and I'm trying to make the triangles spin around. The blobs and triangles are not responding at all, even though I can see that they have the styling applied when I inspect the html. The circles have some effect, but not the one I want.

enter image description here enter image description here


Here is the code for each

circles.scss

    .circles > circle {
        animation: shake 2.2s cubic-bezier(.36,.07,.19,.97) both;
    }
    
    @keyframes shake {
      10%, 90% {
        transform: translate3d(-1px, 0, 0);
      }
      
      20%, 80% {
        transform: translate3d(2px, 0, 0);
      }
    
      30%, 50%, 70% {
        transform: translate3d(-4px, 0, 0);
      }
    
      40%, 60% {
        transform: translate3d(4px, 0, 0);
      }
    }

triangles.scss

    .triangles > g > path {
        animation: triangle-animation 2.2s cubic-bezier(.36,.07,.19,.97) both;
    }
    
    @keyframes triangle-animation {
      10%, 90% {
        tranform: rotate(5deg);
      }
      
      20%, 80% {
        tranform: rotate(90deg);
      }
    
      30%, 50%, 70% {
        tranform: rotate(180deg);
      }
    
      40%, 60% {
        tranform: rotate(30deg);
      }
      100% { 
          tranform: rotate(0deg);
      }
    }

waves.scss

    .waves > path {
      animation: wave-animation 4s infinite alternate;
    //   animation-duration: 4s;
    //   animation-iteration-count: infinite;
    //   animation-direction: alternate;
    }
    
    @keyframes wave-animation {
      0%   {
        margin-left:0px;
        margin-top:0px;
        }  
      50%  {
        margin-left:-2000px;
        margin-top:200px;
        }  
      100% {
        margin-left:0px; 
        margin-top:0px;
        }
    }

And this is my main App.js file

    import React from 'react';
    
    import Blobs from 'svg/Blobs.svg'
    import Circles from 'svg/Circles.svg';
    import Triangles from 'svg/Triangles.svg';
    
    export default () => (
        <div>
            <Circles className="circles" />
            <Blobs className=" w-100 h-100 waves" />
            <Triangles className='w-100 triangles' />                
        </div>
    );

The styles are imported in index.js

Create components with the svg code inside then add your css classes ... I advise you to start from scratch and create your own svg, it's easier than using already created svg.

(check the demo at the bottom of the page with the triangles, circles and waves)

App.js

import React from 'react';
import './style.css';

import Triangles from './svg/Triangles';

export default function App() {
  return (
    <div>
      <Triangles />
    </div>
  );
}

Triangles.js

import React from 'react';

export default function Triangles() {
  return (
    <div className="triangles">
      <svg className="triangle one">
        <path d="M150 0 L30 200 L270 200 Z" />
      </svg>
      <svg className="triangle two">
        <path d="M120 0 L30 180 L200 200 Z" />
      </svg>
      <svg className="triangle three">
        <path d="M10 0 L40 280 L190 170 Z" />
      </svg>
    </div>
  );
}

style.css

/* Triangles */
.triangles {
  position: relative;
  display: flex;
  align-items: center;
  justify-content: center;
  width: 100%;
  height: 50vh;
}
.triangle {
  position: absolute;
  fill: rgb(23, 233, 224);
  fill-opacity: 0.4;
  animation-name: spin;
  animation-iteration-count: infinite;
  animation-timing-function: linear;
}
.triangle.one {
  height: 210px;

.triangle.two {

.triangle.three {
  height: 120px;

QUESTION

How to distort an array of images - Processing

Asked 2021-Jun-05 at 20:15

I am trying to distort a grid of images that are displayed randomly when the mouse is clicked.

I have the grid and the random when click.

I have accomplished the distorsion I want when I have only one image.

Now I have to merge both codes together, but I can't figure out how to do it when the PImage is an array.

Grid code:

PImage img[];
int nPics;

int w, h;

void loadImages(){
  for (int i = 0; i < nPics; i++) {
    img[i] = loadImage("img_"+ nf(int(random(0, 687)), 3) + ".jpg");
    imageMode(CORNERS);
  }
}

void setup() {
  size(1500, 500);
  nPics=27;
  img = new PImage[nPics];

  w=width/9;  
  h=height/3; 

  loadImages();
}

void mousePressed(){
  loadImages();
}

void draw() {
  background(0);
  for (int i=0; i<nPics; i=i+3) {  
    int col = i/3;
    for (int row=0; row<3; row++)
      image(img[i+row], col*w, row*h, (col+1)*w, (row+1)*h);
  }
}

Wave code:

PImage myImage;
float speed1 = .01;
float speed2 = 5;

void setup()
{
  size(1500,500);
  myImage = loadImage("img_001.jpg");
}

void draw()
{
  float distortion = map(mouseY, 0,500, 0, 10);
  for (int i = 0; i < myImage.width; ++i) {
    copy(myImage, i,0,1,height, i, (int) (sin((millis()+i*speed2)*speed1)*distortion),1,height);
  }
}

ANSWER

Answered 2021-Jun-05 at 20:15

If you want to apply the distortion to the entire canvas, you can just use copy() without the image parameter. This causes it to just copy from what is currently on the canvas.

You can use a very similar for loop to the one that's in your wave code, just omit the myImage parameter and let i go from 0 to width instead of myImage.width. Then you put it at the end of your draw block in the grid code:

//global variables, include speed1 and speed2

void loadImages() {
  //as in grid code
}

void setup() {
  //as in grid code...
}

void draw() {
  //everything from grid code...

  float distortion = map(mouseY, 0,500, 0, 10);
  for (int i = 0; i < width; ++i) {
    copy(i,0,1,height, //the rest...);
  }
}
