Synfig need some help ...

Will you remember about the synfig software ?
 Seam the team need some help ...
We have enough money to fund Ivan's work until November 1st 2013, but our goal is to continue intensive development of Synfig as long as possible. That's why we have decided to start a fundraising campaign.

Programming with shaders - part 001 .

If you want to working with shaders then you must know something about GLSL data types.
The GLSL data types it's like variables or any types of data from programming language.
Uniform variables
Let's show you this types versus C data types:

bool -- int conditional get true -- or false. 
int -- int signed integer. 
float -- float single floating-point scalar. 
vec2 -- float[2] Two component floating-point vector. 
vect3 -- float[3] Three component floating-point vector. 
vec4 -- float[4] Four component floating-point vector. 
bvec2 -- int[2] Two component Boolean vector. 
bvec3 -- int[3] Three component Boolean vector. 
bvec4 -- int[4] Four component Boolean vector. 
ivec2 -- int[2] Two component signed integer vector. 
ivec3 -- int[3] Three component signed integer vector. 
ivec4 -- int[4] Four component signed integer vector. 
mat2 -- float[4] 2x2 floating-point matrix. 
mat3 float[9] 3x3 floating-point matrix. 
mat4 -- float[16] 4x4 floating-point matrix. 
sampler1D int for accessing a 1D texture. 
sampler2D -- int for accessing a 2D texture. 
sampler3D -- int for accessing a 3D texture. 
samplerCube -- int for accessing a cubemap texture. 
sampler1DShadow -- int for accessing a 1D depth texture. 
sampler2DShadow -- int for accessing a 2D depth texture..

This are the uniform variables and can be treated as constants... so cannot be changed.
The uniform variables are used when is passed from OpenGL app to the shader.
Vertex Attributes
This can only be used with vertex shaders.
The atributes are position, normals, texture coordinates all you can use with GL_ARB-vertex_program.
The GL_ARB-vertex_program holds slots and after overwritten the attribute is lost.
The attributes can be:

arrays, structures,
float,
vec[2],vec[3],vec[4],
mat[2],mat[3],mat[4]

Let's see one simple example
In OpenGL you used something like this:

...
glBegin(GL_TRIANGLES);
...
glVertex3f(0,1,0);
glNormal3f(1,0,1);
glVertex3f(0,1,0);
glNormal3f(1,0,0);
...
glEnd();
...

The link between shader and opengl source code using slot is:

...
int any_slot= 7;
...
glBindAttribLocationARB(my_program, any_slot, "my_attribute");
...
glBegin(GL_TRIANGLES);
...
glVertex3f(0,1,0);
glNormal3f(1,0,1);
glVertex3f(0,1,0);
glNormal3f(1,0,0);
...
glEnd();
...

this will pass the my_attribute to shader program (my_program) using a slot (any_slot).
To working ( access ) with the attribute in shader source code , just use this:

attribute vec3 my_attribute;

Can you see I sent with vec3 type because the glVertex3f has 3 float so is need to be three component floating-point vector.
Varying variables.
This are used most to send data from vertex shader to fragment shader.
The most common example is texture coordinates from vertex shader to fragment shader.
But about how it's vertex and fragment shader in the next tutorial.

Gamescom 2013

I don't have any clue about is on Gamescon, but I found this article
"Gamescom is insane. Multiple giant halls filled with video games, besieged by 200,000 people, all jostling for hands-on time – and swag. While E3 is generally thought of as the industry's major event, this Cologne-based behemoth is the true, public-facing epicentre of the gaming year."
You can see some videos with the most wanted games.
I also like the new Batman: Arkham Origins - Nowhere to Run

Very nice idea with the Murasaki Baby 

And also Watch Dogs...

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..."

News ... Synfig Studio 0.64.0 for Windows is available now.

Synfig is the best , light and easy way to do an animation. I used with linux and is simple tool to make animation. I think this software can be one great educational software. Your child will leave aside the pencil and sketchpad, watercolors to make own animations. Let's see the demo reel from 2012 by Rafael Bardisa.

Corona SDK will come with Vungle monetization platform.

Team Corona introduce Vungle as our new Corona Plugin partner.

Vungle is a video monetization platform that connects advertisers and developers to achieve breakthrough levels of monetization and user engagement. Our goal is to help developers increase revenue without compromising their app’s UX.

Corona developers can take advantage of Vungle.

As we know the Plans and Pricing of Corona SDK start with: free account and come with $49 - Pro, $79 (Enterprise-Small Business) and $199 (Enterprise-Unlimited).

This prices is for developer/month and billed annually.

The Corona is simple to use so can be a good way to help developers increase revenue.

The new Prince of Persia named Prince of Persia Shadow and Flame

The Ubisoft Entertainment come today with and new rebirth of the legendary Prince of Persia Classic.

Now it's working with Google Play and AppStore.

The game has 14 levels rendered in visually-stunning 3D , 15 weapons and what is great : follow the epic storyline of the original game.

News: Khronos releases OpenCL 2.0 and OpenGL 4.4

The Khronos Group announced new releases: OpenCL 2.0 and OpenGL 4.4.

Most of us working with OpenGL and maybe OpenCL and that can be good news.

As you know the OpenGL come long time ago and OpenCL is new in development.

About OpenCL you can read here.

The OpenGL reference can be read also here.

The Khronos Group come also with many features to development like:

OpenGL ES, WebGL, WebCL, COLLADA, glTF, OpenVG, OpenSL ES, OpenMAX AL, OpenMAX IL, EGL, StreamInput, OpenVX, CameraOpenGL SC, OpenMAX DL, OpenKODE, OpenWF, OpenML...

SculptGL the new 3D sculpting online.

Note: This tool has a new interface - the scrrenshot is old.
SculptGL is a useful WebGL application for 3D sculpting.
You can import and export your meshes into OBJ files.
It's came with some features like dynamic subdivision, decimation, uniformisation and adaptive sculpting.
You can test it here.

News : Just only $249 NVIDIA GeForce GTX 760

New NVIDIA GeForce GTX 760 which offers amazing PC gaming performance will come with the new price for only $249.

Read more about this here.

The iPad Pen come with wireless stylus.

This is the wireless stylus that makes taking notes on an iPad seem as natural as writing freehand with pen and paper.

Very nice device . You can read more about this device here.

This is one picture with the iPad Pen, the price : $169.95.

I don't have one iPad so don't tell you more.

I try to see it on youtube and this is the result , thank's TheJoLProductions for share us

Test your browser WebGL with glMatrix.

The glMatrix is designed to perform vector and matrix operations stupidly fast! By hand-tuning each function for maximum performance and encouraging efficient usage patterns through API conventions, glMatrix will help you get the most out of your browsers Javascript engine.

The glMatrix has moved to GitHub.

Test with the new benchmark.

You can test your browser using old google
