- ASE loader is now able to load triangles. Well, their position is not correct, but at least triangles ... 

- jAssimp API WIP. assimp.Mesh interface finished, including JNI implementations. Maybe a few more native functions than necessary, but I want to keep the native parts as simple as possible
- Updates to the documentation

At the moment ASSIMP is able to read Lightwave Object files (.obj), Milkshape3D scene (.ms3d), DirectX scenes (.x),
old 3D Studio Max scene files (.3ds), Doom/Quake model files (.md1 to .md7), 3D Game Studio models (.mdl) and
PLY files (.ply). ASSIMP is independent of the Operating System by nature, providing a C++ interface for easy integration
ASSIMP is able to import the following file formats into your application:
<b>AutoDesk 3D Studio 4/5 (.3ds).</b> The old native format of 3DS max, now still supported and
widely used.
<br>
<b>AutoDesk 3D Studio ASCII Export (.ase).</b> Text format used by 3DS max. Supports bone animations
and highly complex materials.
<br>
<b>DirectX (.x)</b> A file format that can easily be read by D3DX and that is supported
as export format by most 3D modellers. ASSIMP supports both binary and ASCII X-Files.
<br>
<b>Stanford Polygon (.ply)</b> File format developed by the university of
stanford. Thanks to its flexibility it often used for scientific purposes. Supported by ASSIMP
are ASCII and binary PLY files, both LittleEndian and BigEndian.
<br>
<b>WaveFront Object (.obj)</b> File format that is widely used to exchange asset data
between different applications.
<br>
<b>Milkshape 3D (.ms3d)</b> Native file format of the well-known modeller Milkshape 3D.
ASSIMP provides full support for bone animations contained in ms3d files.
<br>
<b>Quake I (.mdl)</b> The file format that was once used by the first part of the
quake series. ASSIMP provides full support for loading embedded textures from Quake models.
<br>
<b>3D GameStudio (.mdl)</b> The file format of Conitecs 3D GameStudio tool suite.
Used by the freeware modelling tool MED. ASSIMP provides full support for all types of
3D GameStudio MDL files: <i>MDL3, MDL4, MDL5, MDL6, MDL7</i>. Bone animations are supported.
<br>
<b>Half-Life/CS:S (.mdl, .smd)</b> The file formats used in half life.
<b>Quake II (.md2)/ Quake III (.md3)</b> Used by many free models on the web, support for
Quake 2's and Quake 3's file formats is a must-have for each game engine. Quake 4 is
existing but not widely used. However, it is supported by ASSIMP (and RavenSoft .mdr is supported, too)
<br>
<b>Doom 3 (.md5)</b> The well-known native file format of the Doom 3 engine, used in
many games. Supports bone animation and advanced material settings.
ASSIMP is independent of the Operating System by nature, providing a C++ interface for easy integration
with game engines and a C interface to allow bindings to other programming languages. At the moment the library runs

Textures:
Textures can have various types and purposes. Sometimes ASSIMP is not able to
determine the exact purpose of a texture. Normally it will assume diffuse as default
purpose. Possible purposes for a texture:
<b>1. Diffuse textures.</b> Diffuse textures are combined with the result of the diffuse lighting term.
<br>
<b>2. Specular textures.</b> Specular textures are combined with the result of the specular lighting term.
Generally speaking, they can be used to map a texture onto specular highlights.
<br>
<b>3. Ambient textures.</b> Ambient textures are combined with the result of the ambient lighting term.
<br>
<b>4. Emissive textures.</b> Emissive textures are combined with the emissive base color of the material.
The result is then added to the final pixel color. Emissive textures are sometimes called
"Self ilumination maps".
<br>
<b>5. Opacity textures.</b> Opacity textures specify the opacity of a texel. They are
normally grayscale images, black stands for fully transparent, white for fully opaque.
<br>
<b>6. Height maps.</b> Height maps specify the relative height of a point on a triangle on a
per-texel base. Normally height maps (sometimes called "Bump maps") are converted to normal
maps before rendering. Height maps are normally grayscale textures. Height maps could also
be used as displacement maps on a highly tesselated surface.
<br>
<b>7. Normal maps.</b> Normal maps contain normal vectors for a single texel, in tangent space.
They are not bound to an object. However, all lighting omputations must be done in tangent space.
There are many resources on Normal Mapping on the internet.
<br>
<b>8. Shininess maps</b> Shininess maps (sometimes called "Gloss" or "SpecularMap") specify
the shininess of a texel mapped on a surface. They are normally used together with normal maps
to make flat surfaces look as if they were real 3d objects.
<br>
Textures are generally defined by a set of parameters, including
<br>
<b>1. The path to the texture.</b> This property is always set. If it is not set, a texture
is not existing. This can either be a valid path (beware, sometimes
it could be a 8.3 file name!) or an asterisk (*) suceeded by a zero-based index, the latter being
a reference to an embedded texture (@link textures more details @endlink). I suggest using code
like this to find out whether a texture is embedded:
@code
aiString path; // contains the path obtained via aiGetMaterialString()
const aiScene* scene; // valid aiScene instance
const char* szData = path.data;
if ('*' == *szData)
{
int index = atoi(szData+1);
ai_assert(index < scene->mNumTextures);
// your loading code for loading from aiTexture's ...
}
else // your loading code to load from a path ...
@endcode
<br>
<b>2. An UV coordinate index.</b> This is an index into the UV coordinate set list of the
corresponding mesh. Note: Some formats don't define this, so beware, it could be that
a second diffuse texture in a mesh was originally intended to use a second UV channel although
ASSIMP states it uses the first one. UV coordinate source indices are defined by the
<i>AI_MATKEY_UVWSRC_<textype>(<texindex>)</i> material property. Assume 0 as default value if
this property is not set.
<br>
<b>3. A blend factor.</b> This is used if multiple textures are assigned to a slot, e.g. two
or more textures on the diffuse channel. A texture's color value is multiplied with its
blend factor before it is combined with the previous color value (from the last texture) using
a specific blend operation (see 4.). Blend factor are defined by the
<i>AI_MATKEY_TEXBLEND_<textype>(<texindex>)</i> material property. Assume 1.0f as default value
if this property is not set.
<br>
<b>4. A blend operation.</b> This is used if multiple textures are assigned to a slot, e.g. two
or more textures on the diffuse channel. After a texture's color value has been multiplied
with its blend factor, the blend operation is used to combine it with the previous color value.
Blend operations are stored as integer property, however their type is aiTextureOp.
Blend factor are defined by the <i>AI_TEXOP_BLEND_<textype>(<texindex>)</i> material property. Assume
aiTextureOp_Multiply as default value if this property is not set. The blend operation for
the first texture in a texture slot (e.g. diffuse 0) specifies how the diffuse base color/
vertex color have to be combined with the texture color value.
