<p align="center" class="header">OGRE (Object-Oriented Graphics Rendering Engine)</p><P ALIGN="center" CLASS="header">The
Sample Applications</P><P ALIGN="center" CLASS="header"><A HREF="http://www.ogre3d.org">http://www.ogre3d.org</A></P><P CLASS="MainHeader">The
Samples</P><P CLASS="MainContent">The samples provided show you the kind of thing
you can do with OGRE. To be fair, we haven't ourselves done any major demos with
it; after all we spend all our time writing the engine! So these demos are just
short snippets showing you how quick it is to get an OGRE application up and running
with little fuss.</P><P>All the samples use a couple of framework classes to make
their jobs easier and the code shorter and more about WHAT you're rendering rather
than HOW you're doing it. Feel free to reuse the framework there, which consists
mainly of a base object called ExampleApplication. This handles all the engine
initialisation and all you need to do is subclass it and override the createScene
method to provide your own scene. You can optionally override any of the other
methods if you wish to have more control over the scene. By default the camera
is controllable via the standard freelook and WASD key combinations, but you can
change this by replacing or subclassing the ExampleFrameListener class.</P><P>How
do you find out what all the terms and classes mean? Take a look at the <A HREF="../Tutorials/index.html">tutorials
section</A> for more information, and the <A HREF="../api/html/index.html">API
reference</A> after this. </P><P CLASS="MainContent">Here's a summary of the examples:</P><TABLE WIDTH="100%" BORDER="1" CLASS="MainContent" CELLSPACING="0">
<TR> <TD WIDTH="114">BezierPatch</TD><TD WIDTH="994">Demonstrates the use of bezier
patches for approximating curved surfaces. Displays a single curved surface at
a predefined subdivision level.</TD></TR> <TR> <TD WIDTH="114"> <P>BSP</P></TD><TD WIDTH="994"><P>Demonstrates
a specialisation of the SceneManager class for a very specific kind of scene -
the indoor level as used by countless first-person shooter games. Loads Quake3Arena
levels.<BR><B>IMPORTANT NOTE:</B> For copyright reasons no Quake3 data can be
distributed with OGRE. You are expected to provide your own level data to use
this example - edit the quake3settings.cfg file to specify the location of your
pak0.pk3 file and the map you wish to load.</P></TD></TR><TR><TD WIDTH="114">BspCollision</TD><TD WIDTH="994">Demonstrates
the use of collision and physics with both movable objects and level geometry.
This demo uses the ReferenceAppLayer library to provide the linkage between OGRE
and ODE, the library which performs the physics. The ReferenceAppLayer is an example
of how to tie other libraries into your applications alongside OGRE for the graphics.</TD></TR><TR><TD WIDTH="114">CubeMapping</TD><TD WIDTH="994">Shows
the effect created when using a cubic reflection map to simulate reflections.
May not work on older cards.</TD></TR><TR><TD WIDTH="114">Dot3Bump</TD><TD WIDTH="994">Demonstrates
per-pixel bump mapping by using the DOT3 extenstion. May not work on older cards.
</TD></TR><TR><TD WIDTH="114">EnvMapping</TD><TD WIDTH="994">Demonstrates the
environment mapping effect which can be applied to texture layers, together with
the blending that can be used to combine multiple texture layers. Also now includes
a few billboards as flare effects</TD></TR><TR><TD WIDTH="114">Lighting</TD><TD WIDTH="994">Demonstrates
the use of dynamic coloured lights. </TD></TR><TR><TD WIDTH="114">ParticleFX</TD><TD WIDTH="994">Demonstrates
particle system effects, using predefined particle scripts.</TD></TR><TR><TD WIDTH="114">SkeletalAnimation</TD><TD WIDTH="994">Demonstrates
skeletal animation where a series of bones are used to animate a mesh (in this
case a walking robot)</TD></TR><TR><TD WIDTH="114">SkyPlane</TD><TD WIDTH="994">Shows
how a skyplane can be used, i.e. a fixed camera-relative plane which can be used
to create a flat sky.</TD></TR><TR><TD WIDTH="114">SkyBox</TD><TD WIDTH="994">Shows
how a skybox is used, creating a complete wrap-around sky</TD></TR><TR><TD WIDTH="114">SkyDome</TD><TD WIDTH="994">Demonstrates
the skydome feature, an illusion of a curved dome above the camera displaying
the sky.</TD></TR><TR><TD WIDTH="114">Transparency</TD><TD WIDTH="994">Shows what
happens when you apply scene-level transparency to an object, i.e. not just blending
between texture layers onthe same object by blending new objects with those already
in the scene.</TD></TR><TR><TD WIDTH="114">TextureFX</TD><TD WIDTH="994">A demo
of a few texture effects (scrolling, scaling, rotating) that can be done with
Ogre's 'Controller' architecture, a way of using input values from one object
(in this case time) to affect another (in this case texture coordinates) by translating
them through a function. This could be as simple as a scale factor, or be a little
more complex such as a wave function.</TD></TR><TR><TD WIDTH="114">Water</TD><TD WIDTH="994">An
example of using a custom Renderable to create a special effect; in this case
rippling water.</TD></TR> </TABLE><P>All the examples are controlled as follows:</P><TABLE WIDTH="100%" BORDER="1" CLASS="MainContent" CELLSPACING="0">

ascend </TD></TR><TR><TD WIDTH="139">PageDown</TD><TD WIDTH="969">Camera descend</TD></TR><TR><TD WIDTH="139">O
& P</TD><TD WIDTH="969">Yaw the root scene node (and thus all the movable
objects in the scene)</TD></TR><TR><TD WIDTH="139">I & K</TD><TD WIDTH="969">Pitch
the root scene node (and thus all the movable objects in the scene)</TD></TR><TR><TD WIDTH="139">F</TD><TD WIDTH="969">Toggle
frame rate stats on/off</TD></TR> </TABLE><P CLASS="MainHeader">Making your own
applications</P><P>Take a look at the <A HREF="../Tutorials/index.html">tutorials</A>,
this is the best place to start to learn OGRE. Note that you must include the
Ogre.material, Ogre.overlay and sample.fontdef in one of your application's resource
locations (see the tutorials for more info about resource locations) since these
provide core scripts for the system.</P><P CLASS="MainHeader"> </P><P CLASS="MainContent" ALIGN="CENTER"><A HREF="../ReadMe.html">Back
