Soya is a 3D engine for Python. The first version of Soya was used in several games including Slune, Balazar and Balazar Brother. Several attempts for writing a second version failed, mainly due to lack of time. Today, the new upcoming version 3 is now available on Bitbucket!

The most strinking new features are:

• Support for the latest Python 3.4 and Blender 2.70

• Vertex shaders and pixel shaders : Soya divides shaders in no less than 20 mini-shaders, allowing to modify a specific part of the rendering without bothering with the rest; additionaly a Pythonic syntax can be used for writing shaders!

• Improved performance: the rendering process has been entirely rewritten, using vertex buffer object (VBO)

• Fullscreen antialiasing

• Per-pixel lighting and cellshading

• GPL v3 license

The development version of Soya 3 can be found on Bitbucket. This version has been tested only under Linux, but it should compile under all major platforms. First screenshots of a secret game project using Soya 3 can be seen here: Secret project.

Is it the first images of a secret game project ? Possibly using the Soya 3D engine ?

The first release of éClaircie, the static and cloud-less blog engine, is available! You can download it here: Download at PyPI

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.

The source code is available in the second part of this post.

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

The attached scripts allow to use Sunbird on PDA, that is to say to wake up automatically the device on Sunbird's alarm. I am successfully using them on the Sharp Netwalker (aka PC-Z1) but it should work on any device that supports wake up on RTC (the Netwalker does only after some hacks) and uses the APM daemon for power-related event management (the Netwalker does ; however for other devices that use ACPI, it should be quite easy to adapt).

To install it, proceed as following:

1. Install the python-pysqlite2 package.

2. Copy the attached file (link below) sunbird_set_next_rtc_alarm.py somewhere on your PATH (for example, in /usr/bin) and make this file executable:

   chmod a+x /usr/bin/sunbird_set_next_rtc_alarm.py

3. Copy the attached file (link below) 50sunbird_rtc_alarm in /etc/apm/suspend.d and make this file executable:

   chmod a+x /etc/apm/suspend.d/50sunbird_rtc_alarm).

4. Edit sunbird_set_next_rtc_alarm.py . At line 3, indicate the maximum time (in second) your device needs to resume from suspend (the default 10 seconds is right for the Netwalker).

5. At line 4, indicate the path to the Sunbird's storage file. if you have no idea at all, the following command should give you some hints:

   ls /home/*/.mozilla/sunbird/*/storage.sdb

That's all! Now, every time you suspend the device, sunbird_set_next_rtc_alarm.py is called. It looks Sunbird's calendar for the closest alarm, and, if any, define the device's RTC alarm as needed. Then, the device will wake up a few second before the alarm, and thus Sunbird will be able to beep you.
