LuxRender 1.4RC1 release

Postby jeanphi » Sat Oct 11, 2014 9:13 am

Hi,

After a long development period we are very pleased to present you the first release candidate of version 1.4. This is going to be a major milestone towards LuxRender 2.0 with many features of LuxRender ported to LuxCore, the new rendering core and the foundation for LuxRender 2.0.
LuxRender itself hasn't gained much new features, but see below for LuxCore improvements, it's quite impressive and it even has brand new features like volume emission or volume precedence that were long awaited. Please remember though that LuxCore is still a RGB only renderer with no spectral capabilities.
There are a few known issues, they should be fixed in the next release candidate, please report any additional issue you might find here or in our bug tracker:
- bump mapping in LuxCore might not work properly in the absence of explicit UV mapping
- area lights intensity might be different in LuxCore compared to LuxRender

Another major fact is that LuxRender is now a member project of the Software Freedom Conservancy. The conservancy provides us with administrative and financial support, which means we can now for example receive donations to help us make an even better renderer and improve its visibility.

You can download packaged builds from our download area, or get the source from our mercurial repositories:
LuxCore: http://src.luxrender.net/luxrays/commit ... er_v1.4RC1
LuxRender: http://src.luxrender.net/lux/commits/tag/v14RC1
LuxBlend: http://src.luxrender.net/luxblend25/commits/tag/v14RC1

And now, the features! Enjoy!

LuxCore new features since v1.3.1:
- new biased path tracing renderer to allow for fast and noise free, but less accurate, renderings, it is available in both CPU and OpenCL flavours with a special realtime mode (Dade can you make a list of current features, tuning knobs, and what's supported in LuxBlend? There is a thread about it, but not sure it is up to date: viewtopic.php?f=34&t=10529)
- Arbitrary Output Values support enabling output of Z buffer, position, material, normal, ... data (Dade, is there a full list? Is it fully supported in LuxBlend?)
- support for light groups
- direct visibility flag to hide objects in direct sight
- full C++ and Python bindings for the API (we should definitely write documentation for that)
- object, camera, materials, ... editing within the API to update the scene on the fly
- fixed mattetranslucent material
- the code is now Apache Public License v2
- new telnet interface
- port of blender procedural textures
- new lxs parser for backward compatibility with LuxRender
- support for quads in mesh definitions (they are split into triangles)
- support for LuxRender tonemappers (autolinear, linear
- point light support with IES support
- IES support to area light source
- support for spot light source
- support for projection light source
- support for constant infinite light source (without image map)
- support for distant light source
- support for velvet material
- support for sky2 light source
- improved VCM bidir implementation
- replaced FreeImage library with OpenImageIO
- support for cloth material
- support for carpaint material
- improved bump and normal mapping to match LuxRender output
- support for area light with null material
- support for volume absorption and scattering (single or multiple)
- support for clear, homogeneous and heterogeneous volumes
- support for volume precedence (to make it easier to work with liquids for example)
- support for arbitrary camera clipping planes
- support for volume emission (with light group support)
- support for gaussian pixel filter
- support for laser light
- support for Blackman-Harris pixel filter
- support for camera response
- support for rough matte material (Oren-Nayar model)
- support for camera autofocus
- support for rough matte translucent material
- support for motion blur (camera, lights, objects, but no deformation yet)
- pixel filters can now have arbitrary sizes

LuxRender new features since v1.3.1:
- update of LuxCore renderer (biaspath support, new light types, new materials, new textures, volumes, new pixel filters, bias path halt condition, light strategies, motion blur)
- fix hair mesh normals
- new interface to render on MS Azure
- FreeImage replaced by OpenImageIO
- antialiasing of the render view

LuxBlend new features since v1.3.1:
- improved hair and particles export
- various fixes to the nodes system
- update LuxCore rendering modes
- default pixel filter is now Blackman-Harris
- render to viewport when using LuxCore
- direct volume data access for Blender >2.71 (faster)
- support for LuxCore specific material settings
- support for LuxCore materials, emission, bump and normal maps

I'm excited about the new laser light support. Is it possible that someone could write a quick tutorial on how to set up laser beams?
