Integrate Jinja2 for preprocessing Shaders

Jinja2 : Use Boost.Python to do more abstraction

Change Math::CMatrix interface

The aims is to reduce the complexity for uses :

Math::CMatrix4 positionMatrix, scaleMatrix;
positionMatrix.SetTranslation(m_Position.x, m_Position.y, m_Position.z);
scaleMatrix.SetScaling(m_Scale.x, m_Scale.y, m_Scale.z);
m_CachedLocalTransformationMatrix = scaleMatrix_m_Orientation.ToMatrix()_positionMatrix;

To :
m_CachedLocalTransformationMatrix = Math::CMatrix4::ScaleMatrix(...)_m_Orientation.ToMatrix()_Math::CMatrix::PositionMatrix(...);

And integrate Math::TVector3f for parameters

Imporve Python Scripts

Rewrite python script make.py for python 3.X

submodules, ...

Imporve Python Scripts

Rewrite python script make.py for python 3.X

submodules, ...

Add Custom attributes verifications

To be sure that : CUSTOM_ATTRIBUT + 1 not apply on an shaders that wait an other attribute.
Use std::string identifier :)

VBO one draw call

Regroup data in structures :

• http://www.opengl.org/wiki/VBO_-_more
• http://www.opengl.org/wiki/Vertex_Buffer_Object

Create Fattal2D technique

Port this technique to GPU.

Use python prototype.

Python Script imporvement

Convert old version of the python Scripts to new syntax to be compatible with python 3.X

Python interpreter error

Use boost::python to manage object and errors.

RenderingBuffer : Need to separate DYNAMIC | STATIC

Multiples changes need in GLBuffers :

• Indice Array is not needed for somes models
• See use of VAO
• Merge & entrelaces VBO data
• Put apart the dynamic VBO data
• Don't need to store CPU data VBO

Improve Define type (Shader)

Use one design pattern to encaspulate define type. (Get a more flexible system)

Improve CMake Findpackage

Use new syntax on FindPackage for CMake :

Example :

# - Find CBLAS
# Find the native CBLAS headers and libraries.
#
#  CBLAS_LIBRARIES    - List of libraries when using cblas.
#  CBLAS_FOUND        - True if cblas found.

Pass to OpenGL 3.1 pure context

Remove all depreciated functions :)

Py_DECREF Debug build window

Problem on Window in DEBUG version

CMake : ROOT_DIR Dependancies

See if there is an possibility to setup root dir for :

• Freetype2
• ZLIB
  Think about the boost integration

Improve geometry drawing

Some ideas :

• Occlusion culling (HWD)
• Instantiating Geometry
• Frustum Culling
• Batching

Jinja2 Input dependance system

Currently use these approch for template requirement :
/*

• Need requirement
• • GridDimension

*/

Might find a solution to have somethings like :
{% required 'GridDimension' 'vec2' %}

And in the child template :
{% variable 'uniform' 'vec2' 'GridDimension' %}
or
{% variable 'in' 'vec2' 'GridDimension' %}

to said : Ok i declare these variable, so dependancies is ok now :)

Python.h remove dependancy for tests

Currently, User need to add the path to 'Python.h'
The idea is to hide this use this ama3D::priv classes or some thing like that

FBO::DrawDebug 2 buffers

For the case there is only two buffer to display (without Depth buffer).

Comportement :
Only one is displayed.

Includes Dependencies

Add dependencies in Amaterasu3D build system to reduce the number of operation for developpers.

Jinja2 Root helpers dir

Set dynamically the root dir.

Remove SDL dependency

Remove SDL (Big dependency) and prefer something like PCM.

Update CMake package

Use new syntax for FindPackage CMake :

One Example :

# - Find CBLAS
# Find the native CBLAS headers and libraries.
#
#  CBLAS_LIBRARIES    - List of libraries when using cblas.
#  CBLAS_FOUND        - True if cblas found.

Create SceneGraph and SceneManager class

Integrate Camera and Light in the SceneGraph.

Choose the same approche used by Ogre3D or Irrlicht :

• API Ogre3D : http://www.ogre3d.org/docs/api/html/classOgre_1_1InstancedGeometry.html
• API Irrlicht : http://irrlicht.sourceforge.net/docu/classirr_1_1scene_1_1_i_scene_node.html

Change Font display technique

Currently, we use freetype lib to handle Font. But there is somes problems to display space, maj, ... etc.

So we need to improve how CGraphicsString are displayed.

One VBO for Font

Puts Only one VBO for Font system

Uniform name "Add methods" in RenderableObject

RenderableObject:

• void AddBuffer(RenderableObject::RenderableBuffer buffer, int typeID)
• void AddTextureMap(TextureType type, TTexturePtr texture)
• void AddMaterial(MaterialType type, Color color)

to :
void AddData(..., ...);
