News: Publish interactive 3D content online .

If you want to publish interactive 3D content online then Sketchfab website help us.
Also you can easily be embedded in any webpage.
The bad thing is not yet designed to display several 3D objects on a single page.
See more here.
You can also buy 3D models. They tell us: Find everything from low poly assets to animated rigs & digital scans for your 3D, virtual reality, and augmented reality projects. With our model inspector, what you see is what you get.

The particles editor from Pixi.js .

The Pixi.js Creator Engine is known by users and java script developers to create digital content with the 2D WebGL renderer.
Today I will show you a publisher created by developers to solve the particle issue.
The parameters specific to each particle system are chosen, the result is viewed and then saved to an output file.
You can test this online tool here.
The result of snow particles is a file created into json style and is this:

The regl and webgl .

The regl is a new functional abstraction for wegbl.
The official website can be found here.

For example, using WebGL, we iterating over points from the CPU to the GPU.
The regl makes it really easy to dive right in and start playing around, like shaders.
Let's see one simple example with points :

const drawPoints = regl({
    frag: '
    // set the precision of floating point numbers
         precision highp float;

         // this value is populated by the vertex shader
    varying vec3 fragColor;

    void main() {
     // gl_FragColor is a special variable that holds the color of a pixel
     gl_FragColor = vec4(fragColor, 1);
    }
    ',

    vert: '
    // per vertex attributes

    }
    ',

    attributes: {
     // each of these gets mapped to a single entry for each of the points.

    },

    uniforms: {
     // by using 'regl.prop' to pass these in, we can specify them as arguments

    },

    // if want points then specify the number of points to draw
    count: points.length,

    // specify that each vertex is a point (not part of a mesh)
    primitive: 'points',
 });
// the next step 
// initialize regl
regl({
  // callback when regl is initialized
  onDone: main
});

Fonts - WOFF fonts - part 001.

Today I will start a new series of tutorials about fonts.
The main reason was that web development and font are very useful both in transmitting content and in the ergonomics of any website.
I will try to highlight less well-researched issues that come to the aid of any type of developer.
The first step is about WOFF and WOFF2 font files.
A WOFF file is a web font file created in the WOFF (Web Open Font Format) format.
This open format used for delivering webpage fonts on the fly.
It is saved as a compressed container and supports TrueType (.TTF) and OpenType (.OTF) fonts. Another good thing allows information about software licensing.

Some benefits of using WOFF:

• web sites using WOFF will use less bandwidth and will load faster than if they used equivalent fonts; 
• many font vendors that are unwilling to license like TrueType OpenType;
• the free-software browser vendors like the WOFF format becoming a truly universal, interoperable font format for the web;
• WOFF files are referenced within CSS files using the @font-face rule;
• WOFF files were replaced with .WOFF2 files;
• the WOFF 2.0 format that features improved compression;
• 
  

One example of use this fonts into CSS - the stylesheet area:

@font-face {
  font-family: 'MyFontWebsite';
  src: url('webfont.eot'); /* IE9 Compat Modes */
  src: url('webfont.eot?#iefix') format('embedded-opentype'), /* IE6-IE8 */
       url('webfont.woff2') format('woff2'), /* Super Modern Browsers */
       url('webfont.woff') format('woff'), /* Pretty Modern Browsers */
       url('webfont.ttf')  format('truetype'), /* Safari, Android, iOS */
       url('webfont.svg#svgFontName') format('svg'); /* Legacy iOS */
}

This table show the browsers support:

Chrome	Safari	Firefox	Opera	IE	Android	iOS
36+	No	35+ with flag	23+	No	37	No

SVG Circus online tool for animated SVG .

This online tool let you to make animation using SVG file format - SVG stands for Scalable Vector Graphics.

  Scalable Vector Graphics is an XML-based vector image format for two-dimensional graphics with support for interactivity and animation. The SVG specification is an open standard developed by the World Wide Web Consortium since 1999. - Wikipedia.

The developer tell us:
SVG Circus enables you to create cool animated SVG spinners, loaders and other looped animations in seconds.

Make fonts for any language.

A problem with your fonts occurs when you do not find the letters specific to the spoken language. This is a simple tutorial about how this online tool can help you.
Select create your font with TEMPLATES from toolbar website .
The next step is selecting from multiple options: basic templates, custom templates, or languages. Modify each letter of the downloaded template.
If you already have an image of your template, click on Upload Template in the toolbar at the top.

The TreeIt 3D software.

This 3D free software allow you to create and export tree.
You can select easy to use and this powerfull real time 3d tree generator.
You can use for the simple creation of your very own 3d tree models or just open default examples.

The glslbin online tool .

This web tool named glslbin can help you to test your shaders online.
Is very simple to use it:

• open the tool;
• delete the source code or change the example;
• run your work ;
• you can also save it.

The development team tell us about this online tool:
glslbin is a fragment shader sandbox similar to ShaderToy or GLSL Sandbox. It's still a work in progress, so expect more to come soon. It adds support for glslify, a GLSL module system which allows you to easily pull in shared code snippets from npm. These modules are all hosted as part of the stack.gl project: you can find a full list of packages in the "Shader Components" section here. Enjoy!
