LuxRender is a most useful rendering engine. LuxRender is a physically based and unbiased rendering engine. Based on state of the art algorithms, LuxRender simulates the flow of light according to physical equations, thus producing realistic images of photographic quality.LuxRender is free program - both for personal and commercial use - and is licensed under the GPL. The software runs on Windows, Mac OS X and Linux. Fully functional exporters are available for many popular 3D packages.LuxRender will save the output image at regular intervals in the same folder as where you exported the .lxs file to. It is also possible to copy the rendered image to the clipboard.1. Physically based renderingLuxRender is built on physically based equations that model the transportation of light. This allows it to accurately capture a wide range of phenomena which most other rendering programs are simply unable to reproduce. This also means that it fully supports high-dynamic range (HDR) rendering.2. Spectral renderingThe core of Luxrender is fully spectral. Unlike traditional rendering software, which only operates on distinct colors (such as red, green and blue), Luxrender uses individual wavelengths. This allows LuxRender to correctly deal with wavelength dependent effects, such as dispersion, or accurately capture the color of incandescent lights. It also makes the rendered images look more natural.3. Optimised rendering methodsLuxRender features various render algorithms. Depending on the kind of scene and whether you're rendering a single image or an animation, choosing the right algorithms can speed up rendering significantly.4. Network renderingLuxRender features support for cooperative cross-platform network rendering. Whether it is on a local network or over the internet, multiple computers can render together, both on animations and on single images. There is no limit on the number of computers that can work together.5. InstancesWhen working on huge projects with multiple copies of the same object, LuxRender's support for instances will significantly save system resources, in particular memory consumption.6. Materials & TexturesLuxRender features a variety of material types. Apart from generic materials such as matte and glossy, physically accurate representations of metals and glass are present. Complex properties such as absorption, dispersive refraction and thin film coating are available.7. Subdivision and displacementUsing displacement, detailed shapes and patterns can be rendered with relatively light models. LuxRender supports subdivision, so detailed displacement can be realised on simple meshes.8. LightingLuxRender supports emitters and environment light sources. All light sources can be either a constant colour, a texture or a user defined spectrum - for example a blackbody colour temperature. For optimal realism, it is recommended to use meshes emitting light instead of point or spot lights.9. CamerasApart from the ubiquitous perspective camera, LuxRender supports orthographic and environment cameras. Using the orthographic camera, one can easily render a front or top view of a model, which can be very handy for architects. The environment camera can be used to produce 360 panoramas or to produce HDR environment map for image based lighting.10. Motion blur, Depth of field and Lens effectsLuxRender features true motion blur, both for the camera and individual objects. Just animate the camera or object, set the shutter time and you're done.11. Light groupsBy using light groups, one can output various light situations from a single rendering, or make adjustments to the balance between light sources in real time. For each light source, intensity and colour can be adjusted on the fly.12. TonemappingInternally, LuxRender stores the result of all light calculations as high dynamic range values. Using either linear or non linear (Reinhard) tone mapping algorithms, these values can be converted to an ordinary low dynamic range image. This process can be influenced in real time, while a histogram aids in finding optimal settings.13. Image denoisingWith strongl algoritms in hand you can rid off remaining noise from rendered images and shorten needed time for your considered final image.14. Fleximage (virtual film)LuxRender's virtual film allows you to pause and continue a rendering at any time. The current state of the rendering can even be written to a file, so that the computer (or even another computer) can continue rendering at a later moment.15. ExportersLuxRender is an external rendering software and relies on exporter scripts that export a scene from a 3d modeling program.16. Cross platformLuxRender is available for Windows, Linux and OS X.17. LicenseLuxRender is and will always be free software, both for private and commercial use. It is being developed by people with a passion for programming and for computer graphics who like sharing their work. We encourage you to download LuxRender and use it to express your artistic ideas.LuxRender is a rendering software and not a 3d modelling application. It relies on other programs to create the scenes to render, including the setup of materials and cameras. Through the use of exporters, all relevant scene information will be written to a file that LuxRender will be able to understand. After opening this file, the only thing LuxRender will do is render the scene. You can however tweak various post processing settings from the graphicall interface of the program.
