+                (affecting the bumpiness) is being controlled by the
+                SMaterial::MaterialTypeParam member. If set to zero, the
+                default value (0.02f) will be applied. Otherwise the value set

+                with which scale the texture is mapped on the material. Too

+                You will not have to drop the pointer to the loaded texture,

-                a technique known as geo mip mapping

-                for reducing the detail of triangle blocks which are far away.

-                The code for the TerrainSceneNode is based on the terrain

-                renderer by Soconne and the GeoMipMapSceneNode developed by

-                Spintz. They made their code available for Irrlicht and allowed

-                it to be distributed under this licence. I only modified some

-                parts. A lot of thanks go to them.

-

-                This scene node is capable of loading terrains and updating

-                the indices at runtime to enable viewing very large terrains

-                very quickly. It uses a CLOD (Continuous Level of Detail)

-                algorithm which updates the indices for each patch based on

-                a LOD (Level of Detail) which is determined based on a patch's

-                distance from the camera.

-

-                The patch size of the terrain must always be a size of 2^N+1,

-                i.e. 8+1(9), 16+1(17), etc.

-                The MaxLOD available is directly dependent on the patch size

-                of the terrain. LOD 0 contains all of the indices to draw all

-                the triangles at the max detail for a patch. As each LOD goes

-                up by 1 the step taken, in generating indices increases by

-                -2^LOD, so for LOD 1, the step taken is 2, for LOD 2, the step

-                taken is 4, LOD 3 - 8, etc. The step can be no larger than

-                the size of the patch, so having a LOD of 8, with a patch size

-                of 17, is asking the algoritm to generate indices every 2^8 (

-                256 ) vertices, which is not possible with a patch size of 17.

-                The maximum LOD for a patch size of 17 is 2^4 ( 16 ). So,

-                with a MaxLOD of 5, you'll have LOD 0 ( full detail ), LOD 1 (

-                every 2 vertices ), LOD 2 ( every 4 vertices ), LOD 3 ( every

-                8 vertices ) and LOD 4 ( every 16 vertices ).

+                a technique known as geo mip mapping
+                for reducing the detail of triangle blocks which are far away.
+                The code for the TerrainSceneNode is based on the terrain
+                renderer by Soconne and the GeoMipMapSceneNode developed by
+                Spintz. They made their code available for Irrlicht and allowed
+                it to be distributed under this licence. I only modified some
+                parts. A lot of thanks go to them.
+
+                This scene node is capable of loading terrains and updating
+                the indices at runtime to enable viewing very large terrains
+                very quickly. It uses a CLOD (Continuous Level of Detail)
+                algorithm which updates the indices for each patch based on
+                a LOD (Level of Detail) which is determined based on a patch's
+                distance from the camera.
+
+                The patch size of the terrain must always be a size of 2^N+1,
+                i.e. 8+1(9), 16+1(17), etc.
+                The MaxLOD available is directly dependent on the patch size
+                of the terrain. LOD 0 contains all of the indices to draw all
+                the triangles at the max detail for a patch. As each LOD goes
+                up by 1 the step taken, in generating indices increases by
+                -2^LOD, so for LOD 1, the step taken is 2, for LOD 2, the step
+                taken is 4, LOD 3 - 8, etc. The step can be no larger than
+                the size of the patch, so having a LOD of 8, with a patch size
+                of 17, is asking the algoritm to generate indices every 2^8 (
+                256 ) vertices, which is not possible with a patch size of 17.
+                The maximum LOD for a patch size of 17 is 2^4 ( 16 ). So,
+                with a MaxLOD of 5, you'll have LOD 0 ( full detail ), LOD 1 (
+                every 2 vertices ), LOD 2 ( every 4 vertices ), LOD 3 ( every
+                8 vertices ) and LOD 4 ( every 16 vertices ).
+                \param heightMapFileName: The name of the file on disk, to read vertex data from. This should
+                be a gray scale bitmap.
+                \param parent: Parent of the scene node. Can be 0 if no parent.

-         * This scene node is capable of very quickly loading

-         * terrains and updating the indices at runtime to enable viewing very large terrains. It uses a

-         * CLOD (Continuous Level of Detail) algorithm which updates the indices for each patch based on

-         * a LOD (Level of Detail) which is determined based on a patch's distance from the camera.

-         *

-         * The Patch Size of the terrain must always be a size of ( 2^N+1, i.e. 8+1(9), 16+1(17), etc. ).

-         * The MaxLOD available is directly dependent on the patch size of the terrain. LOD 0 contains all

-         * of the indices to draw all the triangles at the max detail for a patch. As each LOD goes up by 1

-         * the step taken, in generating indices increases by - 2^LOD, so for LOD 1, the step taken is 2, for

-         * LOD 2, the step taken is 4, LOD 3 - 8, etc. The step can be no larger than the size of the patch,

-         * so having a LOD of 8, with a patch size of 17, is asking the algoritm to generate indices every

-         * 2^8 ( 256 ) vertices, which is not possible with a patch size of 17. The maximum LOD for a patch

-         * size of 17 is 2^4 ( 16 ). So, with a MaxLOD of 5, you'll have LOD 0 ( full detail ), LOD 1 ( every

-         * 2 vertices ), LOD 2 ( every 4 vertices ), LOD 3 ( every 8 vertices ) and LOD 4 ( every 16 vertices ).

-                FullScreen options will be ignored when using the WindowId

-                parameter. Default this is set to 0.

-                To make Irrlicht run inside the custom window, you still will

-                have to draw Irrlicht on your own. You can use this loop, as

-                usual:

-                while (device->run())

-                {

-                }

-                \endcode

-                Instead of this, you can also simply use your own message loop

-                using GetMessage, DispatchMessage and whatever. Calling

-                IrrlichtDevice::run() will cause Irrlicht to dispatch messages

-                internally too.  You need not call Device->run() if you want to

-                do your own message dispatching loop, but Irrlicht will not be

-                able to fetch user input then and you have to do it on your own

-                using the window messages, DirectInput, or whatever. Also,

-                you'll have to increment the Irrlicht timer.

-                An alternative, own message dispatching loop without

-                device->run() would look like this:

-                \code

-                MSG msg;

-                while (true)

-                {

-                        if (PeekMessage(&msg, NULL, 0, 0, PM_REMOVE))

-                        {

-                                TranslateMessage(&msg);

-                                DispatchMessage(&msg);

-

-                                if (msg.message == WM_QUIT)

-                                        break;

-                        }

-

-                        // increase virtual timer time

-                        device->getTimer()->tick();

+                To make Irrlicht run inside the custom window, you still will
+                have to draw Irrlicht on your own. You can use this loop, as

+                Instead of this, you can also simply use your own message loop
+                using GetMessage, DispatchMessage and whatever. Calling
+                IrrlichtDevice::run() will cause Irrlicht to dispatch messages
+                internally too.  You need not call Device->run() if you want to
+                do your own message dispatching loop, but Irrlicht will not be
+                able to fetch user input then and you have to do it on your own
+                using the window messages, DirectInput, or whatever. Also,
+                you'll have to increment the Irrlicht timer.
+                An alternative, own message dispatching loop without
+                device->run() would look like this:
+                \code
+                MSG msg;
+                while (true)

+                You can change the color of the highlights using
+                \code
+                sceneNode->getMaterial(0).SpecularColor.set(255,255,255,255);

+                The specular color of the dynamic lights
+                (SLight::SpecularColor) will influence the the highlight color
+                too, but they are set to a useful value by default when
+                creating the light scene node. Here is a simple example on how

+                \code
+                // load and display mesh
+                scene::IAnimatedMeshSceneNode* node = smgr->addAnimatedMeshSceneNode(
+                smgr->getMesh("data/faerie.md2"));
+                node->setMaterialTexture(0, driver->getTexture("data/Faerie2.pcx")); // set diffuse texture
+                node->setMaterialFlag(video::EMF_LIGHTING, true); // enable dynamic lighting
+                node->getMaterial(0).Shininess = 20.0f; // set size of specular highlights
+
+                // add white light
+                scene::ILightSceneNode* light = smgr->addLightSceneNode(0,
+                        core::vector3df(5,5,5), video::SColorf(1.0f, 1.0f, 1.0f));

-

- \section intro Introduction

-

-  Welcome to the irrXML API documentation.

-  Here you'll find any information you'll need to develop applications with

-  irrXML. If you look for a tutorial on how to start, take a look at the \ref irrxmlexample,

-  at the homepage of irrXML at <A HREF="http://www.ambiera.com/irrxml/">www.ambiera.com/irrxml/</A>

-  or into the SDK in the directory example.

-

-  irrXML is intended to be a high speed and easy-to-use XML Parser for C++, and

-  this documentation is an important part of it. If you have any questions or

-  suggestions, just send a email to the author of the engine, Nikolaus Gebhardt

-  (niko (at) irrlicht3d.org). For more informations about this parser, see \ref history.

-

-  \section features Features

-

-  irrXML provides forward-only, read-only

-     access to a stream of non validated XML data. It was fully implemented by

-        Nikolaus Gebhardt. Its current features are:

-

-        - It it fast as lighting and has very low memory usage. It was

-        developed with the intention of being used in 3D games, as it already has been.

-        - irrXML is very small: It only consists of 60 KB of code and can be added easily

-        to your existing project.

-        - Of course, it is platform independent and works with lots of compilers.

-        - It is able to parse ASCII, UTF-8, UTF-16 and UTF-32 text files, both in

-        little and big endian format.

-        - Independent of the input file format, the parser can return all strings in ASCII, UTF-8,

-        UTF-16 and UTF-32 format.

-        - With its optional file access abstraction it has the advantage that it can read not

-        only from files but from any type of data (memory, network, ...). For example when

-        used with the Irrlicht Engine, it directly reads from compressed .zip files.

-        - Just like the Irrlicht Engine for which it was originally created, it is extremely easy

-        to use.

-        - It has no external dependencies, it does not even need the STL.

-

-        Although irrXML has some strenghts, it currently also has the following limitations:

-

-        - The input xml file is not validated and assumed to be correct.

-

-    \section irrxmlexample Example

-

-    The following code demonstrates the basic usage of irrXML. A simple xml

-        file like this is parsed:

-    \code

-        <?xml version="1.0"?>

-        <config>

-                <!-- This is a config file for the mesh viewer -->

-                <model file="dwarf.dea" />

-                <messageText caption="Irrlicht Engine Mesh Viewer">

-                Welcome to the Mesh Viewer of the &quot;Irrlicht Engine&quot;.

-                </messageText>

-        </config>

-        \endcode

-

-        The code for parsing this file would look like this:

-        \code

-        #include <irrXML.h>

-        using namespace irr; // irrXML is located in the namespace irr::io

-        using namespace io;

-

-        #include <string> // we use STL strings to store data in this example

-

-        void main()

-        {

-                // create the reader using one of the factory functions

-

-                IrrXMLReader* xml = createIrrXMLReader("config.xml");

-

-                // strings for storing the data we want to get out of the file

-                std::string modelFile;

-                std::string messageText;

-                std::string caption;

-

-                // parse the file until end reached

-

-                while(xml && xml->read())

-                {

-                        switch(xml->getNodeType())

-                        {

-                        case EXN_TEXT:

-                                // in this xml file, the only text which occurs is the messageText

-                                messageText = xml->getNodeData();

-                                break;

-                        case EXN_ELEMENT:

-                                {

-                                        if (!strcmp("model", xml->getNodeName()))

-                                                modelFile = xml->getAttributeValue("file");

-                                        else

-                                        if (!strcmp("messageText", xml->getNodeName()))

-                                                caption = xml->getAttributeValue("caption");

-                                }

-                                break;

-                        }

-                }

-

-                // delete the xml parser after usage

-                delete xml;

-        }

-        parser has originally been a part of the

-        <A HREF="http://irrlicht.sourceforge.net" >Irrlicht Engine</A>. But because

-        the parser has become very useful with the latest release, people asked for a

-        separate version of it, to be able to use it in non Irrlicht projects. With

-        irrXML 1.0, this has now been done.

+
+ \section intro Introduction
+
+  Welcome to the irrXML API documentation.
+  Here you'll find any information you'll need to develop applications with
+  irrXML. If you look for a tutorial on how to start, take a look at the \ref irrxmlexample,
+  at the homepage of irrXML at <A HREF="http://www.ambiera.com/irrxml/">www.ambiera.com/irrxml/</A>
+  or into the SDK in the directory example.
+
+  irrXML is intended to be a high speed and easy-to-use XML Parser for C++, and
+  this documentation is an important part of it. If you have any questions or
+  suggestions, just send a email to the author of the engine, Nikolaus Gebhardt
+  (niko (at) irrlicht3d.org). For more informations about this parser, see \ref history.
+
+  \section features Features
+
+  irrXML provides forward-only, read-only
+     access to a stream of non validated XML data. It was fully implemented by
+        Nikolaus Gebhardt. Its current features are:
+
+        - It it fast as lighting and has very low memory usage. It was
+        developed with the intention of being used in 3D games, as it already has been.
+        - irrXML is very small: It only consists of 60 KB of code and can be added easily
+        to your existing project.
+        - Of course, it is platform independent and works with lots of compilers.
+        - It is able to parse ASCII, UTF-8, UTF-16 and UTF-32 text files, both in
+        little and big endian format.
+        - Independent of the input file format, the parser can return all strings in ASCII, UTF-8,
+        UTF-16 and UTF-32 format.
+        - With its optional file access abstraction it has the advantage that it can read not
+        only from files but from any type of data (memory, network, ...). For example when
+        used with the Irrlicht Engine, it directly reads from compressed .zip files.
+        - Just like the Irrlicht Engine for which it was originally created, it is extremely easy
+        to use.
+        - It has no external dependencies, it does not even need the STL.
+
+        Although irrXML has some strenghts, it currently also has the following limitations:
+
+        - The input xml file is not validated and assumed to be correct.
+
+    \section irrxmlexample Example
+
+    The following code demonstrates the basic usage of irrXML. A simple xml
+        file like this is parsed:
+    \code
+        <?xml version="1.0"?>
+        <config>
+                <!-- This is a config file for the mesh viewer -->
+                <model file="dwarf.dea" />
+                <messageText caption="Irrlicht Engine Mesh Viewer">
+                Welcome to the Mesh Viewer of the &quot;Irrlicht Engine&quot;.
+                </messageText>
+        </config>
+        \endcode
+
+        The code for parsing this file would look like this:
+        \code
+        #include <irrXML.h>
+        using namespace irr; // irrXML is located in the namespace irr::io
+        using namespace io;
+
+        #include <string> // we use STL strings to store data in this example
+
+        void main()
+        {
+                // create the reader using one of the factory functions
+
+                IrrXMLReader* xml = createIrrXMLReader("config.xml");
+
+                // strings for storing the data we want to get out of the file
+                std::string modelFile;
+                std::string messageText;
+                std::string caption;
+
+                // parse the file until end reached
+
+                while(xml && xml->read())
+                {
+                        switch(xml->getNodeType())
+                        {
+                        case EXN_TEXT:
+                                // in this xml file, the only text which occurs is the messageText
+                                messageText = xml->getNodeData();
+                                break;
+                        case EXN_ELEMENT:
+                                {
+                                        if (!strcmp("model", xml->getNodeName()))
+                                                modelFile = xml->getAttributeValue("file");
+                                        else
+                                        if (!strcmp("messageText", xml->getNodeName()))
+                                                caption = xml->getAttributeValue("caption");
+                                }
+                                break;
+                        }
+                }
+
+                // delete the xml parser after usage
+                delete xml;
+        }
+        \endcode
+
+        \section howto How to use
+
+        Simply add the source files in the /src directory of irrXML to your project. Done.
+
+        \section license License

+
+        As lots of references in this documentation and the source show, this xml
+        parser has originally been a part of the
+        <A HREF="http://irrlicht.sourceforge.net" >Irrlicht Engine</A>. But because
+        the parser has become very useful with the latest release, people asked for a
+        separate version of it, to be able to use it in non Irrlicht projects. With
+        irrXML 1.0, this has now been done.

+
+        This file includes everything needed for using irrXML,
+        the XML parser of the Irrlicht Engine. To use irrXML,
+        you only need to include this file in your project:
+
+        \code
+        #include <irrXML.h>
+        \endcode
+
+        It is also common to use the two namespaces in which irrXML is included,
+        directly after including irrXML.h:
+
+        \code
+        #include <irrXML.h>
+        using namespace irr;
+        using namespace io;
+        \endcode
+        */
+
+} // end namespace io
+} // end namespace irr

- *

- * \section intro Introduction

- *

- * Welcome to the Irrlicht Engine API documentation.

- * Here you'll find any information you'll need to develop applications with

- * the Irrlicht Engine. If you are looking for a tutorial on how to start, you'll

- * find some on the homepage of the Irrlicht Engine at

- * <A HREF="http://irrlicht.sourceforge.net" >irrlicht.sourceforge.net</A>

- * or inside the SDK in the examples directory.

- *

- * The Irrlicht Engine is intended to be an easy-to-use 3d engine, so

- * this documentation is an important part of it. If you have any questions or

- * suggestions, just send a email to the author of the engine, Nikolaus Gebhardt

- * (niko (at) irrlicht3d.org).

- *

- *

- * \section links Links

- *

- * <A HREF="namespaces.html">Namespaces</A>: A very good place to start reading

- * the documentation.<BR>

- * \section irrexample Short example

- *

- * A simple application, starting up the engine, loading a Quake 2 animated

- * model file and the corresponding texture, animating and displaying it

- * in front of a blue background and placing a user controlable 3d camera

- * would look like the following code. I think this example shows the usage

- * of the engine quite well:

- *

- * \code

- * #include <irrlicht.h>

- * using namespace irr;

- *

- * int main()

- * {

- *      // start up the engine

- *      IrrlichtDevice *device = createDevice(video::EDT_DIRECT3D8,

- *              core::dimension2d<u32>(640,480));

- *

- *      video::IVideoDriver* driver = device->getVideoDriver();

- *      scene::ISceneManager* scenemgr = device->getSceneManager();

- *

- *      device->setWindowCaption(L"Hello World!");

- *

- *      // load and show quake2 .md2 model

- *      scene::ISceneNode* node = scenemgr->addAnimatedMeshSceneNode(

- *              scenemgr->getMesh("quake2model.md2"));

- *

- *      // if everything worked, add a texture and disable lighting

- *      if (node)

- *      {

- *              node->setMaterialTexture(0, driver->getTexture("texture.bmp"));

- *              node->setMaterialFlag(video::EMF_LIGHTING, false);

- *      }

- *

- *      // add a first person shooter style user controlled camera

- *      scenemgr->addCameraSceneNodeFPS();

- *

- *      // draw everything

- *      while(device->run() && driver)

- *      {

- *              driver->beginScene(true, true, video::SColor(255,0,0,255));

- *              scenemgr->drawAll();

- *              driver->endScene();

- *      }

- *

- *      // delete device

- *      device->drop();

- *      return 0;

- * }

- * \endcode

- *

- * Irrlicht can load a lot of file formats automaticly, see irr::scene::ISceneManager::getMesh()

- * for a detailed list. So if you would like to replace the simple blue screen background by

- * a cool Quake 3 Map, optimized by an octree, just insert this code

- * somewhere before the while loop:

- *

- * \code

- *      // add .pk3 archive to the file system

- *      device->getFileSystem()->addZipFileArchive("quake3map.pk3");

- *

- *      // load .bsp file and show it using an octree

- *      scenemgr->addOctreeSceneNode(

- *              scenemgr->getMesh("quake3map.bsp"));

- * \endcode

- *

- * As you can see, the engine uses namespaces. Everything in the engine is

- * placed into the namespace 'irr', but there are also 5 sub namespaces.

- * You can find a list of all namespaces with descriptions at the

- * <A HREF="namespaces.html"> namespaces page</A>.

- * This is also a good place to start reading the documentation. If you

- * don't want to write the namespace names all the time, just use all namespaces like

- * this:

- * \code

- * using namespace core;

- * using namespace scene;

- * using namespace video;

- * using namespace io;

- * using namespace gui;

- * \endcode

- *

- * There is a lot more the engine can do, but I hope this gave a short

- * overview over the basic features of the engine. For more examples, please take

- * a look into the examples directory of the SDK.
