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));
}

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:

The glTF - GL Transmission Format exporter for Blender 3D.

According to KhronosGroup this format:
glTF™ (GL Transmission Format) is a royalty-free specification for the efficient transmission and loading of 3D scenes and models by applications. glTF minimizes both the size of 3D assets, and the runtime processing needed to unpack and use those assets. glTF defines an extensible, common publishing format for 3D content tools and services that streamlines authoring workflows and enables interoperable use of content across the industry.

As you already know:
The Khronos Group, Inc. is an American non-profit member-funded industry consortium based in Beaverton, Oregon, focused on the creation of open standard, royalty-free application programming interfaces (APIs).
The glTF 1.0 specification has been announced since October 19, 2015 and it's in Draft since April 11, 2017.

Now you can test it with a Blender addon exporter from here.

The official exporter for Blender use glTF - version 2.0.

Blender 3D addon with the base muscle system.

The ManuelbastioniLAB is an open source and free addon for Blender.
The goal is to create a scientific and powerful 3D humanoids editor with the result of the research and released as a free and open source advanced addons for Blender 3D software.
The last features is the advanced rigging for the base muscle system.
Let's see this into next video from official youtube channel:

News: Blender 3D project 2016.

The new year come with news for Blender 3D users.

The Blender 3D team has a new 3D project named:Caminandes 3.

You can see this funny trailer from Blender Foundation on youtube channel.

Also if you see more about Blender team and how to do it, then you can see this old documentary about making of Sintel:

News: Blender 3D version 2.72

The new Blender 3D software has arrived with new features and tools.
I test it and is a great job make by the Blender 3D team. The splash is great ...
About the application the new features cand be found here.
 ... or the features that are currently in development:
 - GSOC Painting additions
 - Pie Menus
 - Freestyle Rendering for Cycles
 - Rewritten Array Modifier
 - Dragging Masks with Handles
 - New Drag Handles
 - Intersect Tool
 - HSL Color Ramps
 - Sun Beams Node
 - Cycles Reflective and Refractive Caustics
 - Cycles experimental GPU Kernel
 - Cycles Anamorphic Bokeh.
I like also the Pie menu from user interface :

About news you can see some video here.
Great job.

Making Money with Blender...

"Then I joined the Australia Army Reserves, in hopes turning into a “real man” overnight. But I kept daydreaming about how I would make my surroundings in Blender (no joke), so I was constantly chewed out at boot camp for not listening..."

New Blender 2.65

From official website :

The Blender Foundation and online developer community is proud to present Blender 2.65. We focused on making this the most stable release in the 2.6 cycle yet, fixing over 200 bugs.

Fire simulation was added along with many improvements in smoke simulation. In Cycles, motion blur, open shading language and anisotropic shading support was added. For mesh modeling, the bevel tool was much improved, a new symmetrize mesh tool was added, and new Laplacian smooth, decimate, and triangulate modifiers are available.

The new release of Blender 3D version 2.65 it's arrived on December 10th, 2012.

Over 200 bugs have been fixed.

Go and try this wonderful software from here.

Blender Conference 2012

The place it's Amsterdam.

Also, the registration fees give access to all events and are including drinks and daily lunch.

Anyway ... All you need is on blender website.

Blender 3D - ISSUE 28: Blender 2.5

As you know the magazine Blender Magazine is a magazine known to those who use Blender 3D software.
The title of this magazine is "Blender 2.5. In this issue we find some interesting articles related to version 2.5.
However I expect some to be more specific. I expected to find some more specific tutorials.
New version 2.5 has new tools and hardware required. For this reason I wanted to see something more complex.
The magazine comes with sample files. However it seems that the magazine is a success.
