Love2d - the most simple game engine with Lua programming language .

The development team tell us about this software:
Hi there! LÖVE is an *awesome* framework you can use to make 2D games in Lua. It's free, open-source, and works on Windows, Mac OS X, Linux, Android and iOS.
Even if they say it is a framework, most of them who use it already consider it a game engine. You can download it and read about this game engine on the official website After download you need to create a project folder and put the lua scripts for love .
I named this folder test.
I add to this folder one transparent image from internet with the filename: oldpaper.png, see next image:

I create a file named main.lua and I add this lua script:

local imageFile

function love.load()

    imageFile = love.graphics.newImage("oldpaper.png")
end

function love.grid_text()
local gx = 0 
local gy = 0
local g = 0
 while g ~= 100 do
    love.graphics.line( gx, 0, gx, 10)
    love.graphics.setColor( 111, 255, 255 )
    love.graphics.line( 0, gy, 10, gy)
    love.graphics.setColor( 111, 255, 255)
    gx=gx+50 
    gy=gy+50 
    g=g+1
 end
    love.graphics.setColor( 16, 5, 255)
    love.graphics.print("Hello world ! Lua and Love 2D for games !", 290,400)
    love.graphics.setColor(0, 0, 0)
end

function love.draw()
    love.graphics.setBackgroundColor(0, 0, 0)
    love.grid_text()
 -- this displays the normally colored image
    love.graphics.setColor(255, 255, 255, 255)
    love.graphics.draw(imageFile,250,100)
end

Run it outside of test folder with:

 love.exe test

The result of this code is this screenshot.

Unity 3D and the Puppet2D tool .

This tool can help you to animate sprites with Unity 3D.

News: C# IN GODOT game engine.

The development team come with this news:
In order to bring C# programming to Godot, we are embedding the Mono runtime into the engine. As of alpha2, Godot is using Mono 5.2 and C# 7.0 is supported.
I will write more posts about the internals and how things work in the future but, for this one, I would like to focus on introducing the language and how to write Godot scripts with it.
One example of script it's that script class show by the development team :

// Coin.cs
using Godot; // Namespace that contains all Godot types

// Class Coin has same name as its file. Godot will detect it
public class Coin : Node
{
    public override void _Ready()
    {
        GD.Print("Hello, Godot!");
    }
}

Blender 3D - simple gold material .

This tutorial show you how to make a simple gold material with Blender 3D - version 2.79 .
The base of this tutorial come from this link.
Open a new scene and add your object. Select the render from Blender Render to Cycles Render from top of the Blender 3D software.
Create a new material click on Use Nodes button from Material tab.
The next step is to chose screen layout to Compositing.
You will see a Node Editor and set this to Shader to edit your material.
In this window you can change the material object from default Diffuse BSDF to new gold material. 
Use Shift A keys to search and add all you need to make the gold material.
This is the result of nodes for this material:

Blender 3D - Open Shading Language tutorial - part 001 .

Using this tutorial about Open Shading Language, you can try a glass shader. The source code show a simple use for Fresnel equations. The backfacing() and raytype() are two functions that provide the shader some information about the state of the renderer and the scene at the time of evaluation. I used just backfacing(), because is a raw example of this Fresnel equations. As you can see the I, N, eta inputs from Fresnel_Dielectric() is used to get a result variable fr. The all result of this shader is bsdf like a equation. See the next code:

#define IOR_THRESHOLD 1.000000001

float Fresnel_Dielectric(vector i, normal n, float eta)
{
//see https://en.wikipedia.org/wiki/Fresnel_equations
    float c = fabs(dot(i, n));
    float g = eta * eta - 1 + c * c;
    float result = 1.0;
    
    if (g > 0) {
        g = sqrt(g);
        float a = (g - c) / (g + c);
        float b = (c * (g + c) - 1) / (c * (g + c) + 1);
        result = 0.5 * a * a * (1 + b * b);
    }
    
    return result;
}

shader glass(
    color diffuse_col = 1.8, 
    float ior = 1.45, 
    output closure color bsdf = 0)
{
    float real_ior = max(ior, IOR_THRESHOLD);
    float eta = backfacing()? 1.0 / real_ior : real_ior;
    float fr = Fresnel_Dielectric(I, N, eta);
    
    bsdf = diffuse_col * (fr * reflection(N) + (1.0 - fr) * refraction(N, eta));
}

The Storyboarder free tool.

The development team tell us about this free tool named Storyboarder:
Storyboarder makes it easy to visualize a story as fast you can draw stick figures. Quickly draw to test if a story idea works. Create and show animatics to others. Express your story idea without making a movie.
...
Wonder Unit is a studio that makes movies. We spend a lot of time in creative development, building tools, and being smarter about creating the best stories.
This tool come with six simple drawing tools , boards (add a board, draw, duplicate, copy, paste) and metadata for a board (duration, dialogue, action and note).

How can be used this tool? 
You can start with your script or an empty board.
Then just draw each board and add all settings like: duration, dialogue, action and note.
You can export your work to Premiere, Final Cut, Avid, PDF, or Animated GIF.
You can edit your board with Photoshop.
You can improve this software with your source code using github.com - storyboarder.
You can download it from official website.

The EaselJS java script libraries.

The team development teel us:
A suite of modular libraries and tools which work together or independently to enable rich interactive content on open web technologies via HTML5.

• EASELJS - working with the HTML5 Canvas;
• TWEENJS - for tweening and animating HTML5 and JavaScript properties;
• SOUNDJS -  work with audio on the web;
• PRELOADJS - manage and co-ordinate the loading of assets and data;

These javascript libraries are used and used to create web content for all modern desktop and mobile browsers.
To include the EaselJS libraries in your project by linking to the CreateJS CDN it is necessary to link them with script tag :

src="https://code.createjs.com/easeljs-0.8.2.min.js"

The official site offers readers only some modest demo about the capabilities of these libraries for creating web content.

Blender 3D - Open Shading Language tutorial.

Today, I will show you how to use the Open Shading Language with Blender 3D version 2.79.
Use the Scripting area from Screen layout and Cycles for rendering.
Select from Render tab and check the option:Open Shading Language.
Add your object to test this tool.
For example you can use the default Cube.
Add a material to this object.
The Scripting area from Screen layout come with editor text.
Use Templates - > Open Shading Language -> Empty Shader and add this OSL script:

shader marble (color Col = .5, float freq = 1.0,  
           output color result = 0)  
{  
float sum = 0;  
float freq_value = freq;  

point pixel_shader = transform ("object", P);  
for (int i = 0; i < 6; i++)   
{  
    sum = sum + 1/freq_value * abs(.5 - noise( 4 * freq_value * pixel_shader)) ;  
    freq_value = 2 * freq_value;  
}  
result = Col * sum;  
}  

Save this script into your folder . Add a OSL script interface into Node Editor using : Add -> Script -> Script.
This will come with a open dialog icon to add your OSL script.
Link result to Color from your material Diffuse BSDF. All this steps I tell you is on the next image:
