-======Yafaray======
-[[http://yafaray.org|Yafaray]] is a ray-tracing rendering engine that uses the Monte Carlo method (which depends on random sampling to speed along computations) in calculating a scene's light.
-<WRAP notice prewrap 50%>
-<WRAP rightalign>
-===== Strengths [Weaknesses] =====
-</WRAP>
-**Farm-Supported**
-<WRAP indent>
-Yafaray is a fairly well-known renderer and some commercial render farms officially support it, so you can submit jobs and have Yafaray work for you in the "cloud".
-</WRAP>
-**Features**
-<WRAP indent>
-Yafaray has a number of optimisations to help you get good performance without relying on OpenCL or CUDA. It has advanced features like volumetrics, several texture types, various illumination types.
-</WRAP>
-**Industry-Grade**
-<WRAP indent>
-Luxrender features professional-grade features, including lighting groups, volumetrics, instancing, motion blur, depth of field, tone mapping, de-noising, and much more. This is a serious renderer.

-===== Weaknesses [Strengths] =====
-</WRAP>
-**Big**
-<WRAP indent>
-Luxrender is a serious, professional renderer. If you're just learning how to model or light, it might be overkill as an initial rendering setup.
-</WRAP>
-**OpenCL/CUDA**
-<WRAP indent>
-Many of Luxrender's most advanced features expect you to have a powerful computer with a powerful GPU.

-===== Install =====
-Installing Yafaray broadly requires, like other renderers, the installation of the Luxrender base package, and then the plugin that will make it useful in your application of choice (probably [[blender]]).
-To get the basic Luxrender package installed, first install its dependencies; all of them are available from [[http://slackbuilds.org]] but some (like OpenCL) are optional.
-<code>
-BUILDPYTHON=yes ./yafaray.SlackBuild
-</code>
-Once the dependencies are installed, install Luxrender from [[http://slackbuilds.org]].
-==== OpenCL ====
-OpenCL is an open specification that enables a system to access and recruit any computing device for the computational workload. In practise, that usually means the graphics card (GPU) but in theory it could include more.
-OpenCL increases the render speed substantially, but it does require sufficiently powered hardware, and for LuxRender to utilise OpenCL, you must [[opencl|enable OpenCL]] on your system.
-The default behaviour of the SlackBuild is to install LuxRender with OpenCL support. To disable it, start the SlackBuild with a leading ''OPENCL=no'' variable setting:
-<code>
-$ OPENCL=no ./luxrender.SlackBuild
-</code>
-or, if you use ''sport'':
-<code>
-$ OPENCL=no sport i luxrender
-</code>
-If you do not know what OpenCL is, you probably do not //need// it.
-==== Blender ====
-The default behaviour of the LuxRender SlackBuild is to auto-detect whether you have Blender installed, and where its ''script'' directory is located, and to install the LuxRender Blender plug-in. You can forego this automatic detection process by just providing the path manually:
-<code>
-$ BLENDER=/path/to/blender/scripts ./luxrender.SlackBuild
-</code>
-Or, if you would rather the Blender plug-in not be installed, set it to ''no'':
-<code>
-$ BLENDER=no ./luxrender.SlackBuild
-</code>
-If you set ''BLENDER=no'' then the plugins are stored, uninstalled, in ''/usr/share/luxrender-X.X''.
-===== Usage =====
-LuxRender has several ways for you to interact with it. To try it out, use the ''LuxTime'' example stored in ''/usr/share/luxrender-X.X''. Copy the ''LuxTime'' directory to your home directory and then load the ''.lxs'' file to produce a render.
-LuxRender can be invoked as a shell application:
-<code>
-$ luxconsole /path/to/file.lxs
-</code>
-LuxRender has a stand-alone GUI frontend, which you can launch from the **K Menu** or from a shell:
-<code>
-$ luxrender&
-</code>
-[{{ luxrender.jpg?666 |The LuxRender GUI rendering an image by **freejack**.}}]
-And finally, the Blender plugin, which can be activated and used the same as any other Blender plugin:
-  - Activate the Blender plugin in the **User Preferences** panel → **Render**. (There is no need to install the plugin as you might other Blender addons, because the LuxRender installer from SlackBuilds has already installed it for you.)
-  - Make it your active renderer in the *Info* panel
