Browse Source 
First commit to make some structure in doc/ directory.

- moved source/blender/python/doc -> doc/python_api
- moved source/gameengine/PyDoc/*.rst -> doc/python_api/rst
- modified accordingly sphinx_doc_gen.py and sphinx_doc_gen.sh
  (later on I'll try alternative/ scripts by neXyon as promised :)
- source/gameengine/PyDoc/ is still there because contains epydoc stuff for the bge, will ask more and look into it later

# Blender.BGL module (OpenGL wrapper)
"""
The Blender.BGL submodule (the OpenGL wrapper).
B{New}: some GLU functions: L{gluLookAt}, etc.
The Blender.BGL submodule
=========================
(when accessing it from the Game Engine use BGL instead of Blender.BGL)
This module wraps OpenGL constants and functions, making them available from
within Blender Python.
The complete list can be retrieved from the module itself, by listing its
contents: dir(Blender.BGL). A simple search on the net can point to more
than enough material to teach OpenGL programming, from books to many
collections of tutorials.
The "red book": "I{OpenGL Programming Guide: The Official Guide to Learning
OpenGL}" and the online NeHe tutorials are two of the best resources.
Example::
import Blender
from Blender.BGL import *
from Blender import Draw
R = G = B = 0
A = 1
title = "Testing BGL + Draw"
instructions = "Use mouse buttons or wheel to change the background color."
quitting = " Press ESC or q to quit."

len2 = Draw.GetStringWidth(instructions + quitting)

class IDGroup:
"""
The IDGroup Type
================
This type supports both iteration and the []
operator to get child ID properties.
You can also add new properties using the [] operator.
For example::
group['a float!'] = 0.0
group['an int!'] = 0
group['a string!'] = "hi!"
group['an array!'] = [0, 0, 1.0, 0]
group['a subgroup!] = {"float": 0.0, "an int": 1.0, "an array": [1, 2],
"another subgroup": {"a": 0.0, "str": "bleh"}}
Note that for arrays, the array type defaults to int unless a float is found
while scanning the template list; if any floats are found, then the whole
array is float. Note that double-precision floating point numbers are used for
python-created float ID properties and arrays (though the internal C api does
support single-precision floats, and the python code will read them).
You can also delete properties with the del operator. For example:
del group['property']
To get the type of a property, use the type() operator, for example::
if type(group['bleh']) == str: pass
To tell if the property is a group or array type, import the Blender.Types module and test
against IDGroupType and IDArrayType, like so::
from Blender.Types import IDGroupType, IDArrayType.

Most logic brick's methods are accessors for the properties available in the logic buttons.
Consult the logic bricks documentation for more information on how each logic brick works.
There are also methods to access the current :class:`bge.types.KX_Scene`
.. code-block:: python
# Get the current scene
scene = bge.logic.getCurrentScene()
# Get the current camera
cam = scene.active_camera
Matricies as used by the game engine are **row major**
``matrix[row][col] = float``
:class:`bge.types.KX_Camera` has some examples using matricies.
*********
Variables
*********
.. data:: globalDict
A dictionary that is saved between loading blend files so you can use it to store inventory and other variables you want to store between scenes and blend files.
It can also be written to a file and loaded later on with the game load/save actuators.
.. note:: only python built in types such as int/string/bool/float/tuples/lists can be saved, GameObjects, Actuators etc will not work as expected.
.. data:: keyboard
The current keyboard wrapped in an :class:`~bge.types.SCA_PythonKeyboard` object.

if obj:
# do something
pass
The face paremeter determines the orientation of the normal.
* 0 => hit normal is always oriented towards the ray origin (as if you casted the ray from outside)
* 1 => hit normal is the real face normal (only for mesh object, otherwise face has no effect)
The ray has X-Ray capability if xray parameter is 1, otherwise the first object hit (other than self object) stops the ray.
The prop and xray parameters interact as follow.
* prop off, xray off: return closest hit or no hit if there is no object on the full extend of the ray.
* prop off, xray on : idem.
* prop on, xray off: return closest hit if it matches prop, no hit otherwise.
* prop on, xray on : return closest hit matching prop or no hit if there is no object matching prop on the full extend of the ray.
The :class:`KX_PolyProxy` 4th element of the return tuple when poly=1 allows to retrieve information on the polygon hit by the ray.
If there is no hit or the hit object is not a static mesh, None is returned as 4th element.
The ray ignores collision-free objects and faces that dont have the collision flag enabled, you can however use ghost objects.
:arg objto: [x, y, z] or object to which the ray is casted
:type objto: :class:`KX_GameObject` or 3-tuple

:type xray: integer
:arg poly: polygon option: 0, 1 or 2 to return a 3-, 4- or 5-tuple with information on the face hit.
* 0 or omitted: return value is a 3-tuple (object, hitpoint, hitnormal) or (None, None, None) if no hit
* 1: return value is a 4-tuple and the 4th element is a :class:`KX_PolyProxy` or None if no hit or the object doesn't use a mesh collision shape.
* 2: return value is a 5-tuple and the 5th element is a 2-tuple (u, v) with the UV mapping of the hit point or None if no hit, or the object doesn't use a mesh collision shape, or doesn't have a UV mapping.
:type poly: integer
:return: (object, hitpoint, hitnormal) or (object, hitpoint, hitnormal, polygon) or (object, hitpoint, hitnormal, polygon, hituv).
* object, hitpoint and hitnormal are None if no hit.
* polygon is valid only if the object is valid and is a static object, a dynamic object using mesh collision shape or a soft body object, otherwise it is None
* hituv is valid only if polygon is valid and the object has a UV mapping, otherwise it is None
:rtype:

.. class:: KX_MeshProxy(SCA_IObject)
A mesh object.
You can only change the vertex properties of a mesh object, not the mesh topology.
To use mesh objects effectively, you should know a bit about how the game engine handles them.
#. Mesh Objects are converted from Blender at scene load.
#. The Converter groups polygons by Material. This means they can be sent to the renderer efficiently. A material holds:
#. The texture.
#. The Blender material.
#. The Tile properties
#. The face properties - (From the "Texture Face" panel)
#. Transparency & z sorting
#. Light layer
#. Polygon shape (triangle/quad)
#. Game Object
#. Verticies will be split by face if necessary. Verticies can only be shared between faces if:
#. They are at the same position
#. UV coordinates are the same
#. Their normals are the same (both polygons are "Set Smooth")
#. They are the same colour, for example: a cube has 24 verticies: 6 faces with 4 verticies per face.

Sets the material state setup object.
Using this method, you can extend or completely replace the gameengine material
to do your own advanced multipass effects.
Use this method to register your material class. Instead of the normal material,
your class's activate method will be called just before rendering the mesh.
This should setup the texture, material, and any other state you would like.
It should return True to render the mesh, or False if you are finished. You should
clean up any state Blender does not set before returning False.

.. method:: getRGBA()
Gets the colour of this vertex.
The colour is represented as four bytes packed into an integer value. The colour is
packed as RGBA.
Since Python offers no way to get each byte without shifting, you must use the struct module to
access colour in an machine independent way.
Because of this, it is suggested you use the r, g, b and a attributes or the colour attribute instead.
.. code-block:: python
import struct;
col = struct.unpack('4B', struct.pack('I', v.getRGBA()))
# col = (r, g, b, a)
# black = ( 0, 0, 0, 255)
# white = (255, 255, 255, 255)
:return: packed colour. 4 byte integer with one byte per colour channel in RGBA format.
:rtype: integer
.. method:: setRGBA(col)
Sets the colour of this vertex.
See getRGBA() for the format of col, and its relevant problems. Use the r, g, b and a attributes
or the colour attribute instead.
setRGBA() also accepts a four component list as argument col. The list represents the colour as [r, g, b, a]
with black = [0.0, 0.0, 0.0, 1.0] and white = [1.0, 1.0, 1.0, 1.0]
.. code-block:: python

v.setRGBA([1.0, 0.0, 0.0, 1.0]) # Red
v.setRGBA([0.0, 1.0, 0.0, 1.0]) # Green on all platforms.

.. attribute:: joint_rotation
Control bone rotation in term of joint angle (for robotic applications), read-write.
When writing to this attribute, you pass a [x, y, z] vector and an appropriate set of euler angles or quaternion is calculated according to the rotation_mode.
When you read this attribute, the current pose matrix is converted into a [x, y, z] vector representing the joint angles.
The value and the meaning of the x, y, z depends on the ik_dof_x/ik_dof_y/ik_dof_z attributes:
* 1DoF joint X, Y or Z: the corresponding x, y, or z value is used an a joint angle in radiant
* 2DoF joint X+Y or Z+Y: treated as 2 successive 1DoF joints: first X or Z, then Y. The x or z value is used as a joint angle in radiant along the X or Z axis, followed by a rotation along the new Y axis of y radiants.
* 2DoF joint X+Z: treated as a 2DoF joint with rotation axis on the X/Z plane. The x and z values are used as the coordinates of the rotation vector in the X/Z plane.
* 3DoF joint X+Y+Z: treated as a revolute joint. The [x, y, z] vector represents the equivalent rotation vector to bring the joint from the rest pose to the new pose.
:type: vector [x, y, z]
.. note::
The bone must be part of an IK chain if you want to set the ik_dof_x/ik_dof_y/ik_dof_z attributes via the UI, but this will interfere with this attribute since the IK solver will overwrite the pose. You can stay in control of the armature if you create an IK constraint but do not finalize it (e.g. don't set a target) the IK solver will not run but the IK panel will show up on the UI for each bone in the chain.
.. note::
[0, 0, 0] always corresponds to the rest pose.
.. note::
You must request the armature pose to update and wait for the next graphic frame to see the effect of setting this attribute (see :data:`BL_ArmatureObject.update`).
.. note::
You can read the result of the calculation in rotation or euler_rotation attributes after setting this attribute.

Usage:
For HTML generation
-------------------
- Run this script from blenders root path once you have compiled blender
./blender.bin -b -P doc/python_api/sphinx_doc_gen.py
This will generate python files in doc/python_api/sphinx-in/,
assuming that ./blender.bin is or links to the blender executable
- Generate html docs by running...
sphinx-build doc/python_api/sphinx-in doc/python_api/sphinx-out
assuming that you have sphinx 0.6.7 installed
For PDF generation
------------------
- After you have built doc/python_api/sphinx-in (see above), run:
sphinx-build -b latex doc/python_api/sphinx-in doc/python_api/sphinx-out
cd doc/python_api/sphinx-out
