2010-05-27T15:12:00.000-07:00

MeeGo, the fusion of Maemo+Moblin based on qt 4.6 release today!

Here some tutorial to start developping from scratch :

Now I m going to count the days until to get a KDE port :)

translatoid with remember option

2009-11-13T13:08:00.000-08:00

Translatoid is a very usefull plasmoid for people like me with some difficult to speak english, spanish , german etc....
If you have used translatoid before, maybe you notice that you translate many time the same word or sentence..
So, now translatoid will remember for you some word you have already translated. For example, if you want to remember a translation, just click on the yellow star, and translatoid will remember it in a sqlite file. And after, translatoid will be able to show you random sentences or words!
I m using now Extender plasmoid to do that and it's very usefull!!

Wait for the release, I will publish it tonight.

Here a video !!

Gluon in Full activity

2009-10-11T07:12:00.000-07:00

As you can see, tsdgeos During the Gluon Sprint has found the best postition to work ! :)

Gluon First technical preview

2009-10-05T15:33:00.000-07:00

Today I invite you to test the first technical preview of gluon. Currently there is some bug and a lot of feature are missing, particulary the documentation. Leinir has start to develop Gluon creator and we plan to finish it during the qt sprint in munich this week end.
So, if you want to install this library to have a preview, go here : http://gluon.tuxfamily.org/wiki/index.php?title=Installation

Here you can test a game preview called block..or blok.. we didn't decide it...!
http://gitorious.org/gluon/block

And just for eyes, some screenshot and video :

There is no sound on the video because I cannot record it with gtk recordmydesktop... :( ! But if you test it, you will !

Karicature

2009-08-01T16:23:00.000-07:00

Today, I started a new Kde application for games, particulary expected to Gluon.
It called Karicat, an avatar creator in the same kind of mii avatar on wii. So, Currently There are no many sprite (Thanks to Eugene for all)!
So I invite Everybody who want to create new svg face element!Here the svg file.
The core application works nice, except animations for now... yes it moves!
This is a screenshot :

About Gluon

I am proud to present you our new Website , with a very nice new logo.
http://gluon.tuxfamily.org/ ! ( Thanks Ken)
We are working hard to provide a good games api as soon as possible... Currently we are trying to use 3d inside KGL with ODE physicsEngine. I hope it will works...! Be patient , you will like it!
And this video just for eyes : a preview of the first gluon games.

Just for fun...

2009-07-21T15:42:00.001-07:00

I Found today, 2 funny plasmoid, the one on the other ( I don't think it's random...) If someone want to know the percentage between Atheist and Christian in kde communauty, just look the number of fan :)

KCLEngine and evdev

2009-07-19T10:15:00.001-07:00

Hi all,I started to work on KCL and it looks very powerfull now! KCLEngine read input information in a qthread using the evdev system.
Then KCL support all input device avaible for linux. Not only the keyboard, mouse and joystick... but a lot of other device like wiimote, webcam button etc....

Example of code using Virtual Button :
KCLEngine * kcl = new KCLEngine;
kcl->addInput(KCLEngine::MOUSE); //add first mouse detected
kcl->addInput(KCLEngine::KEYBOARD);//add standard keyboard

KCLInput * joystick = new KCLInput("/dev/input/event4");
kcl->addInput(joystick); //This is an other way to add an Input.

Now in the game mainLoop()
{

if (( kcl->button("MouseLeft") && ( kcl->button("Key_Right") && (kcl->button("JoyButton12"))
kDebug()<<"you made a combo!!!!";
}

So, other good feature with KCL, is that you can use more one mouse in the same time. (yes yes!!) I think you can imagine all the possibility, for example de multiplayer games on the same screen!
For example :

KCLMouse * mouse = KCLMouse("/dev/input/event4") //first mouse;
KCLMouse * mouse2 = KCLMouse("/dev/input/event6"); //second mouse

in the mainLoop
{
drawPoint(mouse.position());
drawPoint(mouse2.position());
}

So, now if you don't believe me, Look this video :

Webcam for kde : a new way for gluon games ?

2009-05-22T14:16:00.000-07:00

Hi all!

Yesterday I had an idea, to use a webcam input as a controller for games! Like the last nintendo games. So, I was looking on openCV to get the video source and use some video detection function. My plan is to load Webcam picture to KGLTexture, and use them in KGLEngine

Otherwise, I don't understand why KDE has no official webcam librairy/software. Phonon cannot use it currently... Gnome has Cheese, and it's exellent.
So, I create a small KCamWidget worked on openCV. ( look the screenshot)

kcamwidget.cpp
kcamwidget.h

If some people want to work on the beginning of this project, there are welcome! The code source is here
Ps : I suggest you to compile openCV with gstreamer enabled!
For me, I think I will developp a gluonWebcam application which provide GPU Shaders effects in real time, and sound recording! ( yes, KAL know record sound!)

When Convolution matrix meets KGLShader

2009-05-19T06:16:00.000-07:00

Today I have implemented Matrix Convolution as a shader for KGL. Matrix convolution is an easy way to create simple effects with a simple matrix computation.
For example, you can use it in Gimp.
But the difference between Gimp and KGL, is so important. Gimp use the CPU and KGL use the GPU thanks shaders! So, now you can easily make realtilme animation with convolution effects what can not do CPU.
Thanks olivier gueudelot for the idea!

So , look this :
Normal Texture {0,0,0, 0,1,0, 0,0,0}

Contrast effect {0,-1,0, -1,5,-1, 0,-1,0}

Border detection {0,1,0, 1,4,1, 0,1,0}

Random Value ( I don't remeber the matrix :))

Blur effect {1,1,1, 1,1,1, 1,1,1}

Bump effect {-2,-1,1, -1,1,1, 1,1,2}

( Don't forget to contact me , or join us on irc.freenode.net #gluon, if you want to help us in this project

KGL support now shaders

2009-05-17T08:58:00.000-07:00

KGLEngine support now shaders effects. I m using the code from KGLLIB. Thanks rivo !
I show you my first shader effect : the Blur effect !!
Look the video here

And here a simple shader editor!

GLUON : KGLPhysicsWidget

2009-05-04T09:06:00.000-07:00

Lot of improvement this week on KGLEngine. Now KGLEngine use box2D library to simulate physics world. It works with KGLPhysicsWidget and KGLPhysicsItem and it's so easy and funny to play with it. So I give you a video preview and screenshots of a kde tower!

new dataEngine : translator

2009-04-22T10:49:00.001-07:00

I create today, a new DataEngine wich allow you to translate anything. Currently it use only the Google translator like translatoid. But it's easy now to develop new translator by create a new class inheriting from AbstractTranslator.

So, Can you suggest me some idea of web translator ? Babylon? and ..?

new Nvidia display driver

2009-03-30T15:25:00.000-07:00

Just a new to inform you of the last nvidia driver release wich fix plasma bug. We can read in the release highlights : "Fixed OpenGL crashes while running KDE4's Plasma."

For my personal test, ( Geforce 8800GTX) :
-The system tray work properly now...
-I have a color gradient inside my popup plasmoid...
-Plasmoid motion seems to be very fast now?!

GLUON new website

2009-03-27T08:40:00.000-07:00

Hi, Planet ! Good New today ! Now KGL, KAL, KCL have joined force and now there are called Gluon. For this new change, I have created a new website that you can find here : http://gluon.tuxfamily.org/. And you can contact us by joining on irc : irc.freenode.net #gluon.
If you want to help us in this project, you are welcome! Just contact me! Currently I have tom make a small break for my study( 2 weeks max). After I will come back to finalize KCLEngine and make a good documentation.

KGLengine+ Box2d the physicsEngine

2009-03-09T08:07:00.000-07:00

Hi all !
Maybe you have already play Crayon Physics Games ? So, this games use the fabulous Box2D library.

So I decided to test it in KGLEngine.... And it's amazing how Box2d and KGLengine are complementary...
So, look the video ( click on picture)

So, now we have to create some class and make compatibility between eigen and Box2d.

Important :
I will create a website about our hight level game api ( KGLengine = opengl render, KALengine = sound render based on openAL, KInputEngine=control input)... I want a generic name which regroup all sub library, a bit like "directX" or like Löve . So I invite you to send me your Idea for this name.

And with binary plasmoid...

KALEngine new feature

2009-03-06T05:32:00.000-08:00

new important improvment : Phonon support and ogg/vorbis player.
I just want to signal a point about KALEngine and phonon. KALEngine will not be a competitor of phonon. It's not same! Phonon is for sound application like a media player. It works like this :

MediaObject *media = new MediaObject(this);
connect(media, SIGNAL(finished()), SLOT(slotFinished());
media->setCurrentSource("/home/username/music/filename.ogg");
media->play();

While KALEngine is for games sound. It provide multi-channel players , 3d sound and some effects like Doppler effect. It works like this :

KALEngine * soundEngine = new KALEngine();
KALSource * source = new KALSource("explosion.wav", soundEngine);
source->play();
source->setPosition(x,y,z);
delete soundEngine;

Advantage of phonon :
- only qt dependent
- load a lot of sound file, like mp3 and ?video?

Disadvantage of phonon :
- not easy to use for games! Particulary the multi-channel !
- no 3d sound manager.

Advantage of KALEngine :
- based on openAL. Very Powerfull ( all 3d games use this)
- can play many sound in the same time
- easy to create 3d sound, velocity, doppler...
Disadvantage of KALEngine :
-Can read only wav and ogg file
- depend of : libsoundFile, openAL, Ogg, Vorbis, alut
- too young

Our small team ( DrIDK, packadal , smarter ) is joinable on irc : #kglengine if you want more information about KGLEngine/KALengine developpement.
And just for your fun : here an amazing optic illusion : The color code of case A is the same of case B.

translatoid with alternating icon

2009-02-26T05:21:00.000-08:00

QtPainter is fabulous!! With QTransform::shear, I created a nice alternating icon for translatoid icon popup!
new improvement : TTS support, auto Past, animation for Country listWidget.

KGLEngine + KALEngine = KTank

2009-02-23T15:04:00.000-08:00

Hi, all...this is a quick message, but important!
KGLEngine is now avaible here :
svn co svn://anonsvn.kde.org/home/kde/trunk/playground/games/KGLEngine

Just for your eyes :
the shadow Effects!
ktank Engine with sound Engine!! so nice!!Be sure you have sound enable!

Tutorial 1 : Here the code source , for show you how to create a simple box. You can find the tutorial here Look, how it's easy to use:

KGLEngine2d *engine= KGLEngine2d::instance(); //init engine

engine->setShowAxis(true); //show the placeMark O,x,y

engine->setShowFps(true);   //show fps

engine->show();  //show window engine



KGLItem * box = new KGLItem(QRectF(0,0,0.5,0.5));  //create an item

box->scale(0.5); //reduce the size

box->translate(-box->transformCenter()); //translate the box to the center

box->rotate(M_PI/4); //rotate  with a radius = 45 deg

box->setColor(Qt::white); //setColor! By default, it's white

engine->addItem(box); //add item to the engine

KALEngine... yes "A", it's not a mistake!

2009-02-12T06:29:00.000-08:00

There is something good about holidays after all... ! After finishing my exams, I quickly returned to my keyboard to start programing! First and to train myself, I created 2 plasmoids ( fortunoid,translatoid) and a small geolocalisation-IP app using marble.
Before returning to the development of KGLEngine I have implemented KALEngine.

What is KALEngine, you may ask ?
KALEngine is a C++ wrapped openAL allowing to create games using hight-level sound management. Particulary, the multi-channel output and the 3D sound is now available to the contrary of phonon.
I commit a first preview today. The code source is short, but now, you can easily play sound.

#include QDebug
#include kalsource.h
#include kalengine.h

int main (int argc, char **argv)
{
KALEngine sndEngine;
sndEngine.init();

KALSource * sound = new KALSource("ocean.wav"); //Create a short song

sound->play(); //play the song!

while ( sound->getStatus() == AL_PLAYING) //Wait to the end of the song!
{
qDebug()<getElapseTime();
}

delete sound; //delete buffer and source !
sndEngine.shutdown(); // close sndEngine!

return 0;
}

translatoid

2009-01-30T13:52:00.000-08:00

Just a break between 2 lessons about thyroid and rectum :(, for show you my first plasmoid : translatoid! ( more beautiful picture than my lesson book... :)

translation tool for help developpers!

2009-01-19T04:00:00.000-08:00

Hi all,
This is not a KGLEngine news... sorry! Big Big exam are comming.... But I created in one day, a very usefull small application, for help some guy, like me, who have some difficult to read and speak english ..

It's "gtranslate", a line-command qt application, for translate a text using google translator. g = google and not gnome.. You can download it here! or here.

How is it work ?
just to type in konsole : gtranslate en fr "hello". It will return bonjour.

Some trick to be very fast!
1- KhotKey + xsel : Select and Press for translate!
I created 2 small shell scripts : translator_in.sh translator_out.sh
After, installing "xsel" application, you can run this script by using KHotKey...
Now, I have just to select the text, press Meta+F1 (call translator_out), and a dialog box appears with the translation and copy it into the clipboard.
The second one, "translator_in", show me a dialog input box, for translate very fast.

2- Direct translation in Konversation
If you are using Konversation, you can easily translate inside the chat.
YOu have just to add an Alias in Konversation Seeting->Alias command and add a new one like this : /exec cmd gtranslate .

3- Direct translation in pidgin
Need to install pidgin-plugin-pack and use exec plugin!

4- Translatoid...
I created my first plasmoid, here+screenshot ! It doesn't look pretty, but when I have time, I will make it better.

Ktank new blog pages!

2008-12-10T08:38:00.000-08:00

Hello, everyone! I have changed My wordpress blog to google blog! The reason is, my wordpress page, was hacked and destroyed by a lot of spams... !
Now, I will publish all ktank/KGLengine news here! ( as soon as possible!!)
