-jassimp
--------
-
-Java binding for assimp.
-
-The class model used by jassimp is not a one-to-one mapping of assimps class/
-structure model (due to performance considerations). Please read the javadoc
-descriptions of AiMesh and AiWrapperProvider.
-
-The jassimp.lwjgl package contains a LWJGL specific wrapper provider and some
-application examples using this wrapper
-
-
-
-How To Build
-------------
-
- I) native library, for example by issuing this command in jassimp-native/src:
-
-    $ gcc jassimp.cpp -I/usr/lib/jvm/default/include/ \
-      -I/usr/lib/jvm/default/include/linux -lassimp -shared -fPIC -o libjassimp.so
-
-    libjassimp.so is required at runtime and must be located in java.library.path.
-
-II) Java binding
-    The java library is built using ant. Executing "ant" in the port/jassimp
-    directory should be sufficient to build the library including docs. You
-    still need to build the native library separately, see above
-    
-    The java build is configured to create java 1.6 classes
-
-
-
-Limitations
------------
-
-Not all data imports have been tested yet, especially the countless texture
-parameters. If you find bugs please report them.
-
-jassimp supports most of assimps features. Current limitations are
-* only importing scenes is supported. There are some methods that allow a
-  modification of the returned objects, but these should be considered as
-  work in progress. Full blown export support is planned for a future release 
-* no support for mesh animations
-* no support for embedded textures
-* no support for importer configurations
-* some texture related material properties are not exposed via the API but only 
-  accessible by traversing the list of properties. However this limitation is
-  also present in the c-API ...
-
-
-License
--------
-
-The license for jassimp is the same as the main Assimp license.

-/** 
- * Helper structure to describe a virtual camera.<p> 
- *
- * Cameras have a representation in the node graph and can be animated.
- * An important aspect is that the camera itself is also part of the
- * scenegraph. This means, any values such as the look-at vector are not 
- * *absolute*, they're <b>relative</b> to the coordinate system defined
- * by the node which corresponds to the camera. This allows for camera
- * animations. For static cameras parameters like the 'look-at' or 'up' vectors
- * are usually specified directly in aiCamera, but beware, they could also
- * be encoded in the node transformation. The following (pseudo)code sample 
- * shows how to do it: <p>
- * <code><pre>
- * // Get the camera matrix for a camera at a specific time
- * // if the node hierarchy for the camera does not contain
- * // at least one animated node this is a static computation
- * get-camera-matrix (node sceneRoot, camera cam) : matrix
- * {
- *    node   cnd = find-node-for-camera(cam)
- *    matrix cmt = identity()
- *
- *    // as usual - get the absolute camera transformation for this frame
- *    for each node nd in hierarchy from sceneRoot to cnd
- *      matrix cur
- *      if (is-animated(nd))
- *         cur = eval-animation(nd)
- *      else cur = nd->mTransformation;
- *      cmt = mult-matrices( cmt, cur )
- *    end for
- *
- *    // now multiply with the camera's own local transform
- *    cam = mult-matrices (cam, get-camera-matrix(cmt) )
- * }
- * </pre></code>
- *
- * <b>Note:</b> some file formats (such as 3DS, ASE) export a "target point" -
- * the point the camera is looking at (it can even be animated). Assimp
- * writes the target point as a subnode of the camera's main node,
- * called "<camName>.Target". However this is just additional information
- * then the transformation tracks of the camera main node make the
- * camera already look in the right direction.

-/**
- * A mesh represents a geometry or model with a single material.
- * <p>
- * 
- * <h3>Data</h3>
- * Meshes usually consist of a number of vertices and a series of faces
- * referencing the vertices. In addition there might be a series of bones, each
- * of them addressing a number of vertices with a certain weight. Vertex data is
- * presented in channels with each channel containing a single per-vertex
- * information such as a set of texture coordinates or a normal vector.<p>
- * 
- * Faces consist of one or more references to vertices, called vertex indices.
- * The {@link #getPrimitiveTypes()} method can be used to check what
- * face types are present in the mesh. Note that a single mesh can possess
- * faces of different types. The number of indices used by a specific face can
- * be retrieved with the {@link #getFaceNumIndices(int)} method.
- * 
- * 
- * <h3>API for vertex and face data</h3>
- * The jassimp interface for accessing vertex and face data is not a one-to-one
- * mapping of the c/c++ interface. The c/c++ interface uses an object-oriented 
- * approach to represent data, which provides a considerable 
- * overhead using a naive java based realization (cache locality would be 
- * unpredictable and most likely bad, bulk data transfer would be impossible).
- * <p>
- * 
- * The jassimp interface uses flat byte buffers to store vertex and face data.
- * This data can be accessed through three APIs:
- * <ul>
- *   <li><b>Buffer API:</b> the <code>getXXXBuffer()</code> methods return 
- *     raw data buffers.
- *   <li><b>Direct API:</b> the <code>getXXX()</code> methods allow reading
- *     and writing of individual data values.
- *   <li><b>Wrapped API:</b> the <code>getWrappedXXX()</code> methods provide
- *     an object oriented view on the data.
- * </ul>
- * 
- * The Buffer API is optimized for use in conjunction with rendering APIs
- * such as LWJGL. The returned buffers are guaranteed to have native byte order
- * and to be direct byte buffers. They can be passed directly to LWJGL
- * methods, e.g., to fill VBOs with data. Each invocation of a
- * <code>getXXXBuffer()</code> method will return a new view of the internal
- * buffer, i.e., if is safe to use the relative byte buffer operations.
- * The Buffer API provides the best performance of all three APIs, especially 
- * if large data volumes have to be processed.<p>
- * 
- * The Direct API provides an easy to use interface for reading and writing
- * individual data values. Its performance is comparable to the Buffer API's
- * performance for these operations. The main difference to the Buffer API is
- * the missing support for bulk operations. If you intend to retrieve or modify
- * large subsets of the raw data consider using the Buffer API, especially
- * if the subsets are contiguous.
- * <p>
- * 
- * The Wrapped API offers an object oriented interface for accessing
- * and modifying mesh data. As the name implies, this interface is realized 
- * through wrapper objects that provide a view on the raw data. For each
- * invocation of a <code>getWrappedXXX()</code> method, a new wrapper object
- * is created. Iterating over mesh data via this interface will create many
- * short-lived wrapper objects which -depending on usage and virtual machine-
- * may cause considerable garbage collection overhead. The Wrapped API provides
- * the worst performance of all three APIs, which may nevertheless still be
- * good enough to warrant its usage. See {@link AiWrapperProvider} for more
- * details on wrappers.
- * 
- * 
- * <h3>API for bones</h3>
- * As there is no standardized way for doing skinning in different graphics
- * engines, bones are not represented as flat buffers but as object structure. 
- * Users of this library should convert this structure to the format required 
- * by the specific graphics engine. 
- * 
- * 
- * <h3>Changing Data</h3>
- * This class is designed to be mutable, i.e., the returned objects and buffers 
- * may be modified. It is not possible to add/remove vertices as this would 
- * require reallocation of the data buffers. Wrapped objects may or may not
- * propagate changes to the underlying data buffers. Consult the documentation
- * of your wrapper provider for details. The built in wrappers will propagate
- * changes.
- * <p>
- * Modification of face data is theoretically possible by modifying the face
- * buffer and the faceOffset buffer however it is strongly disadvised to do so
- * because it might break all algorithms that depend on the internal consistency
- * of these two data structures.
