!Description

((SkyX)) pretends to be a photorealistic, simple and fast __sky simulator__.

This page is related to the SkyX wrapper, which allows sky simulation for ((MOGRE|Mogre)) applications.

%help% Note: This wrapper wasn't updated for a longer time. Consider to use the alternative wrapper: [http://www.ogre3d.org/addonforums/viewtopic.php?f=8&t=29491|MSkyX]


!Features

Features of SkyX:

* Atmosphere manager (Atmosphere information, functions that returns the sky colour at a especified direction, ...)
* Sun, Moon and star field
* Layer clouds
* Full volumetric cloud system
* Ground atmospheric light absorcion pass (Allows you to simulate the atmospheric light absorcion in scene objects)
* HDR and LDR support
* Shader Model 2.0 capable (HLSL for the moment)
* Full integration with ((Hydrax)) (water simulation) and code example ([http://www.ogre3d.org/forums/viewtopic.php?f=11&t=52166|HydraxSkyXDemo])
* 2 example applications: Terrain & Volumetric cloud system

__Wrapper notes:__
Lot of classes are wrapped. If you need __missing methods or features__, then __just ask__ [http://www.ogre3d.org/addonforums/viewtopic.php?f=8&t=13172|here] and the wrapper author (boyamer) will add them.

!Download

__Binary download:__
http://code.google.com/p/skyxmogre/downloads/list

Just copy the compiled files into your binary directory (e.g. ''MogreSDK\bin\release'').

__Source code:__ 
[http://code.google.com/p/skyxmogre|code.google.com/p/skyxmogre]

For compilation of the source code you need to set the option "Allow unsafe code" in the project properties of Visual Studio.

How to start using SkyX wrapper for Mogre

__Introduction:__

SkyX wrapper is P/INVOKE wrapper for Mogre 1.7.1.
The wrapper is self included into the SkyX projects and added the export declaration.
To build the wrapper you have to open SkyX project and add Mogre include path into the inclusion path and Mogre lib path into the library path, call Build and if compilation went ok under ''SkyX\SkyX\release'' you should find ''SkyX.dll''.

Copy that dll into your project binary path (e.g. ''Mogre\Bin\Release'')

__.NET application:__

To use SkyX into your application, copy the media files from ''SkyX\media'' into your media path.

Open __resources.cfg__ and add this line to the end, referencing where your SkyX content is. 
Example:
{CODE(wrap="1")}
[SkyX]
FileSystem=../../Media/SkyX
{CODE}

Look also to the [http://code.google.com/p/skyxmogre/source/browse/wiki/HowToStart.wiki|repository description page] - maybe it contains newer information.

__Instruction of a forum post:__

You don't need to add any DLL reference to your project, just make sure the DLL is in the same directory like all your compiled .exe and .dll files (usually somewhere like bin\Debug or bin\Release) and add the files from boyamers repository (''AtmosphereManager.cs'', ''CloudLayer.cs'', and so on). These files contain the managed part (for C#) of the wrapper and contains all the functions and classes you need.


!Usage

Look into the source code of the demo applications.

__TODO: add code snippets__


!Notes

If you get this ''invalid parameters'' error in the ''ogre.log'' file
{CODE(wrap="1")}23:19:46: Parsing script SkyX.material
23:19:46: Compiler error: invalid parameters in SkyX.material(109): param_named and param_indexed properties requires at least 3 arguments{CODE}
Then you should modify the related line of the ''SkyX.material'' file. (The line number you find in the ogre log message. In this example it's line 109.)
{CODE(wrap="1")}param_named uRadius float 30000{CODE}

__Problems with Shadows__ 
''Stencil Shadows'' are used for old hardware with fixed function pipeline, as SkyX is shader based probably there is a problem.
{CODE(wrap="1", colors="c#")}
ShadowTechnique.SHADOWTYPE_STENCIL_ADDITIVE;               // shadows may work, SkyX BROKEN
ShadowTechnique.SHADOWTYPE_STENCIL_MODULATIVE;             // no shadows,       SkyX BROKEN

ShadowTechnique.SHADOWTYPE_NONE;                           // no shadows, SkyX WORKS
ShadowTechnique.SHADOWTYPE_TEXTURE_ADDITIVE;               // no shadows, SkyX WORKS
ShadowTechnique.SHADOWTYPE_TEXTURE_ADDITIVE_INTEGRATED;    // no shadows, SkyX WORKS
ShadowTechnique.SHADOWTYPE_TEXTURE_MODULATIVE;             // no shadows, SkyX WORKS
ShadowTechnique.SHADOWTYPE_TEXTURE_MODULATIVE_INTEGRATED;  // no shadows, SkyX WORKS{CODE}
