LuxRender v1.3 发布!LuxRender 是一款物理真实的、无偏差的开源渲染器。
改进记录包括:
Changes since v1.3RC2:
- SLG renderer will now accept moving objects, but they will be rendered without motion blur
- more fixes to subdivision surfaces (hopefully no crash should happen anymore)
- support for thickness variation along hairs
- lens effects can now be configured from the scene file
- better parameter mapping for SLG renderer
- improved volume export for Blender
- improved hair export for Blender
- lens effects export in Blender
- fix IOR selection in Blender
- fix wood texture export in Blender
- OSX specific fixes for SLG
Other changes since v1.2.1:
- Improved support for Strands (hair).
- Support for vertex colors and alpha.
- Improved lower bound on glossy roughness (0.000001 vs old limit of 0.006), can be made mirror-like now.
- Better out-of-gamut color clamping.
- New "darken" color clamping mode.
- New "abbe" fresnel texture for specifying IOR using Abbe numbers.
- New false color tonemapper.
- New obstacle-map based glare, much faster and much better looking.
- New "heterogeneous" volume type (for smoke etc), along with 3d textures "cloud", "exponential" and "densitygrid".
- New "autopowerimp" light strategy.
- New Catmull-Rom and Blackman-Harris pixel filters.
- New renderer "slgrenderer", which integrates the SLG rendering engine in LuxRender (not interactive though).
- LuxRender now also has "sobol" sampler, faster alternative to the "lowdiscrepancy" sampler.
- Arealights can now be instanced, this allows for motion blurred lights.
- Support for deferred loading of meshes.
- LuxRender executable location has moved to addon preference panel, see Blender Addon page in user preferences.
- Support for node editor!!! Note this is still under development, which may later render your node materials invalid, so use for testing/playing only at this time please.
- support for bump and normal maps when using the mix material and the SLG renderer
- fix for the MQBVH accelerator in SLG when all primitives have the same bounding box
- improved preview in Blender (faster and more accurate)
- fix normal generation for loop subdivided meshes and make loopsubdivision more robust (it should no longer hang nor crash)
- make the IES parser accept more valid IES files
- properly compute sky power so that it can be used with importance light sampling strategies
LuxRender渲染是根据渲染方程来模拟光的传输,生成物理真实的图像。但LuxRender 只是一款渲染程序而不是3D建模程序,它需要其它3D程序来创建包含材质设置和相机设置的场景,然后通过导出脚本,将场景的所有信息都写入一个 LuxRender文件格式的文件中。用LuxRender打开这个文件后,要做的事情只是渲染这个场景。LuxRender基于PBRT项目,但不同之 处在于它关注的是产品渲染和艺术效果而非学术和科学目的。
LuxRender包含一个交互式的用户界面和多个不同的3D程序的导出脚本,包括Blender,Maya和XSI。提供了命令行工具并且还提供 C/C++ API 以使LuxRender能被集成到第三方应用程序。
LuxRender自0.8版本开始提供OpenCL加速渲染功能。
