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!");
    }
}

News: The new released Krita version 3.3.1 .

The Krita development team tell us:

Published    10/11/2017

Today we are releasing Krita 3.3.1, a bugfix release for Krita 3.3.0. This release fixes two important regressions:

Krita would crash if you would restart Krita after closing Krita with the reference images docker set to floating
Krita 3.3.0 could not read .kra backup files or .kra files that were unzipped, then zipped up manually.
Additionally, there are the following fixes and improvements:

Fix a crash when creating a swap file on OSX (Bernhard Liebl).
Merge down does not remove locked layers anymore (Nikita Smirnov)
Various performance improvements, especially for macOS (Bernhard Liebl)
Improve the look and feel of dragging and dropping layers (Bernhard Liebl)
Improve the tooltips in the brush preset selector (Bernhard Liebl)
Fix a memory leak in the color selectors (Boudewijn Rempt)
Fix rotation and tilt when using the Windows Ink api (Alvin Wong)
Don’t allow the fill tool to be used on group layers (Boudewijn Rempt)
Add brightness and contrast sliders for textured brushes (Rad)
Add paste-at-cursor (Dmitry Kazakov)
Improve performance of the cpu canvas (Alvin Wong)
Fix a crash on closing Krita when there is something on the clipboard (Dmitry Kazakov)
Add a button to open a file layer’s image in Krita (Wolthera van Hövell tot Westerflier)

You can read more about this new version of Krita software and download it from here.

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:

Big prizes in objects .

Here's a contest for lovers around the world with awards prize graphics.
The website team tell us about this contest:

  Once upon a time in a land far, far away, there was a tiny kingdom hidden away in the mountains. And while its people were happy and led good lives, in the back of their minds there was always the worry about what might be at the other side of the mountains… 

Welcome to our new community contest! We’ll be going back to medieval times to explore castles, medieval towns, knights, and perhaps… dragons? Anything is possible in this Medieval Fantasy!

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 Skanect software tool for 3D .

The official website come with this intro:
With Skanect, capturing a full color 3D model of an object, a person or a room has never been so easy and affordable. Skanect transforms your Structure Sensor, Microsoft Kinect or Asus Xtion camera into a low cost 3D scanner able to create 3D meshes out of real scenes in a few minutes. Enter the world of 3D scanning now!
Come with free and paid solution, need a good 3D sensor ( see official features on web) and GPU with CUDA.
I install this software and has a good interface.

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.
