News : JavaScript petition to Oracle.

Oracle acquired the JavaScript trademark in 2009 but does not actively use this trademark for commercial products. Its ownership prevents the official use of the JavaScript name in conferences and other events related to the programming language. The petition is supported by prominent figures in the JavaScript community, including the creator of Node.js, Ryan Dahl, and the creator of JavaScript, Brendan Eich. They argue that releasing the trademark would allow the language to evolve and thrive without artificial barriers

See the official website to sign this petition by JavaScript™.

Dear Oracle,

You have long ago abandoned the JavaScript trademark, and it is causing widespread, unwarranted confusion and disruption.

JavaScript is the world’s most popular programming language, powering websites everywhere. Yet, few of the millions who program in it realize that JavaScript is a trademark you, Oracle, control.

Here's what I managed to do for this week:

CodePen: How can share sketchfab 3D models.

The Viewer API lets you build web apps on top of Sketchfab’s 3D viewer. With the API, you can control the viewer in JavaScript. It provides functions for starting, stopping the viewer, moving the camera, taking screenshots and more.

See the official webpage.

CodePen: Webcam with RGB color shader and the three.js javascript library.

Three.js is a cross-browser JavaScript library and application programming interface used to create and display animated 3D computer graphics in a web browser using WebGL.

This library is not really used in website development. It has some great real-time information display capabilities.

Today I show you a combined example of a webcam with a simple shader set with an RGBA color.

CodePen: RGB colors.

Example with the javascript programming language presented in my codepen account solves the following issues:

• create HTML tag div for each for iteration;
• create an id for each div tag;
• build an RGB color with red, green, and blue using a random function;
• read that id and used to set the color background of each div;
• print the RGB value for each color and set background color;

Let's see the example:

CodePen: Lottie for Web, Android, iOS, React Native, and Windows - 001.

Lottie is a mobile library for Web, and iOS that parses Adobe After Effects animations exported as JSON with Bodymovin and renders them natively on mobile!, see GitHub project.

You can find Lottie files on this website. 

This is a simple example with lottie-player.js:

OpenProcessing - simple tree_001.

This is modified example from this in order to build another good tree using openprocessing website interface.

You can see this example on my account.

Let's see the source code:

/*--based on https://openprocessing.org/sketch/396851--*/

var nbranchs = 73;
function setup() {
  createCanvas(640, 400);
  background(0, 0, 128);

  stroke(128);
  noLoop();
}

function draw() {
  tree(100, 200, 150, 350);
}
function mousePressed() {
  background(0, 0, 128);
  redraw();
}

function branch(x, y, dx, dy) {
  var sign = random(dx+1.0)/(abs(dx)+5.0);
  
  for (var i = 0; i <= x; i += 3) {
    var idx = i/x;
    
    var xi = bezierPoint(x, x + dx/2,   x + dx, x + dx, idx);
    var yi = bezierPoint(y, y, y + dy, y + dy, idx);

Another Ct.js game engine.

This is a game engine build and run with javascrip.
You can used on these operating systems: Windows, Linux and Mac OS.
Download the archive for your operating system and unarchive.
Start the ctjs application.
Into the main window you have some editbox for Name, Author name, Homepage and Version.
This window comes with buttons for play, stop ... many tabs: Settings, Rooms, UI, Sound ...
First, you need to fill the Settings with your Name and all data, and add Actions.
This engine game comes with examples to see how good is.
Let's see a video tutorial from Gamefromscratch user:

The wrld for custom maps.

A good map can have many features.
If you don't want to build one using advanced programming language then you can use this website.
You can use this with an online map with Unity, JavaScript, iOS and Android.
You can also build your indoor map and visualize any building in 3D.
All of these features let you optimize building management, resources, and planning.
The map can have many features like time of day, weather and seasons and heat map.
The next example is an outdoor map of my location.

The neon effect with javascript P5 JavaScript library.

The P5.js is a JavaScript library for creative coding.
You can use by adding this link on your HTML area using the script tag:

https://cdnjs.cloudflare.com/ajax/libs/p5.js/0.9.0/p5.min.js

You can use it like any JavaScript library.
You have two functions: setup and a draw for setup and drawing.

function setup() {
  createCanvas(window.innerWidth, window.innerHeight);
}

function draw() {
  ellipse(50, 50, 80, 80);
}

Then you can fill these functions with any javascript code.
You can see a neon effect with two bezier functions.
The example uses the mouse movement to change the bezier lines.
You can see many examples created by me at codepen website.

Using blotter.js with channels.

This javascript library comes with this intro:
A JavaScript API for drawing unconventional text effects on the web. Blotter.js requires Three.js and Underscore.js. If you're already including these files in your project, view the information on custom builds to get the file size significantly smaller.
See more here.
The HTML5 is simple with an empty div tag.
The CSS is just for design an is not affected by the script.
I used this:

https://cdnjs.cloudflare.com/ajax/libs/Blotter/0.1.0/blotter.min.js
https://cdnjs.cloudflare.com/ajax/libs/Blotter/0.1.0/materials/channelSplitMaterial.min.js

If you want a distortion effect you need to use this:

https://cdnjs.cloudflare.com/ajax/libs/Blotter/0.1.0/materials/channelSplitMaterial.min.js

The javascript takes the div tag and used it:

//
let text = new Blotter.Text("28:08:2019", {
  family : "sans-serif",
  size : 128,
  fill : "#000"
});

let material = new Blotter.ChannelSplitMaterial();
material.uniforms.uOffset.value = 0.05;
material.uniforms.uAnimateNoise.value = 1;


let blotter = new Blotter(material, {
  texts : text
});

let el = document.getElementById("blotter-channels");
let scope = blotter.forText(text);

scope.appendTo(el);

The result is this:

Show SVG with the anime javascript library.

First of all the anime javascript library can be found at the official webpage.
Start with the empty project on codepen.io website.
You need to add the javascript library into the editor by using the wheel icon of JS area:

https://cdnjs.cloudflare.com/ajax/libs/animejs/2.2.0/anime.min.js

You can add the SVG source code with the path and then this will be parsed by javascript script.
The CSS code is used to stylize the output.
For example, the size of the path can be used like this:

.anim path {
  stroke-width: 3;
}

Then use the source code from my example.
See the result of this source code:

OpenProcessing website.

You can create an account on this website to test your skills with processing programming language.
About OpenProcessing then this programming language uses some awesome Licensed and Open Source components.

New codepen example - modal window.

In user interface design for computer applications, a modal window is a graphical control element subordinate to an application's main window. It creates a mode that disables the main window, but keeps it visible with the modal window as a child window in front of it.
This is my example with a modal window created on codepen website.
The example is very simple.
The html5 source code is created with classes and id's.
The css file make all style for this tags.
The javascript use all of this to open the modal window, use click to close the window.
The Cancel and Add buttons not work with the java script.
