Here is a very simple but functional Javascript image viewer (< 2ko) with no dependency (not even JQuery).

It is used by éClaircie. For a demonstration, please see the following page: Screenshots.

Cerealizer 0.8.1 is out!

This is a new bugfix release. Get it here: http://download.gna.org/soya/Cerealizer-0.8.1.tar.bz2

Soya 2.0 is coming!

The most striking feature of Soya 2.0 is mini shaders. They allow to write Open GL / GL SL shaders so easily! With GL SL, you have to rewrite the entire rendering pipeline, even if you want to modify only a small part of it...

On the contrary, with Soya's mini shaders, you can write a mini shader that overrides a part of the rendering pipeline (ex customizing the lighting computation), or that adds an extra step in the rendering (ex deforming the model geometry). Then Soya assembles all mini shaders, adds the missing pieces of the rendering pipeline, and generates a GL SL shader.

Additionally, Soya's mini shaders can be written with a Python-like syntax ;)

Soya provides 16 classes mini shaders, each corresponding to a specific part of the rendering pipeline. Here is an example of a "camera-space deform" mini shader, which deforms the model's geometry in camera space:

wavy_mini_shader = soya.MiniShader("wavy", """
uniform float self.time
def void cameraspace_deform_mini_shader():
  current_vertex.x = current_vertex.x + 0.2 * sin(0.2 * self.time + 3 * current_vertex.y)
""")


my_body.add_mini_shader(wavy_mini_shader())

Mini shaders can be associated to any object: a Model, a Body (an instance of Model), a World (a group of other 3D object) or a Material. When associating a mini shader to a World, it is inherited by all objects inside this World, and automagically combined with objects' own mini shaders. For more details about mini shaders, see the mini-shader-* tutos!

Want to try and start hacking with Soya 2? You're welcome! The development version can be obtained on this mercurial repository: http://hg.tuxfamily.org//mercurialroot/oomadness/soya2.

Other new features include:

• Support both Python 2.7 and 3.3,

• Open GL SL shader support,

• new exporters for Blender 2.6x, with a bugfixed Blender => Cal3D exporter, able to take into account vertex location, normal and texture coords when merging vertices,

• LOD support for models,

• pre-rendered background, usefull for slow computer or old-style games,

• Partial Open GL ES support (not yet finished).

Cerealizer 0.8 is out!

This new version supports both Python 2.x and Python 3.x! Get it here: http://download.gna.org/soya/Cerealizer-0.8.tar.bz2

Songwrite 2 0.4 is out ! This major version adds supports for diatonic accordion tablature and chords. Additionally, repeat symbols have been (greatly) improved, and a new starting screen has been added. And many bugs have been fixed. Enjoy!

Songwrite 2 0.3 is out ! This major version proposes an improved interface, more usable on small screens, and adds many functionalities including appoggiatura, harmonics, F keys on staff, strumming direction, rests,... It also supports Koyabu board, ukulele, and lyre tablatures (my new instrument, although I'll probably be the only one to use them :-)). It requires EditObj 2 0.3.

There are also many bugfixes, and the licence is now GPL v3 (instead of v2).

Here is the full change log:

• Touchscreen support

• Lyre, Koyabu board and Ukulele support

• Support for F key, appoggiatura, harmonics, strumming direction and rests

• Smarter copy-paste (autochoose between by string / by note pitch more accurately)

• Name sharp and bemol notes adequately, depending of the tonality

• Add a window's icon

• Fontsize options for screen and printing

• Interval identification: select 2 notes and Songwrite display the corresponding interval in the title bar!

• Licence changed to GPL v3

Bugfixes:

• Lyrics not placed at the bottom were bugged in PS/PDF export/printing

• Printing tabs with staffs was sometime causing an infinite loop

• Printing tabs with staffs was not showing # and b rightly on the staff

• After playing, select the previously selected notes

• When reducing the length of ALL bars, the newly created bars at the end now use the lew length

• Take capo into account when playing

• Can play hammer / pull / legato / slide with no limit of amplitude

• Fix g8 staff

• Fix capo

Here is a graphical presentation of my academic research area... Nobody should now says that it is ununderstandable and obscure !
