Refactored my implementation for Artistic Friendly Marschner to RSL 2.0 format. Still have no free time to accomplish my multiple scattering stuff for hair. Just rendered two samples according the real photo, sorry for my poor artistic creativity. Code is here http://ortholab.codeplex.com/SourceControl/list/changesets.
这是一个相当simple & naive的方法，几行代码完成的CSR稀疏矩阵格式的优化，剔除0元素。由于目前AMD的OpenCL SDK依旧没有赶上NVIDIA CUDA SDK的进度——新的CUDA 4我认为在库的丰富程度上以及易用上已经远远的超过了AMD的实现。虽然如此，今后还是得希望开源社区能够贡献基于OpenCL的数学库，或者我自己搞一个？
This is a rare simple & naive method which is used to optimize sparse matrix, cull the all zero elements. I think the AMD’s OpenCL libraries is stil not as good as NVIDIA CUDA’s. Whatever, I wish there would be some mathmatics libraries from open source society, or I make one in person ?
After spent some time on Alembic, a Mudbox plugin was finished.
The code is at my Ortholab, youi should compile this plugin by your self. Current Alembic has not supplied a pre-built Windows binary so that it will be more comfortable on Linux platform, at the same time, as we know, the most studios are working on Linux platform too.

More compiling details here,
http://ortholab.codeplex.com/wikipage?title=AbcTranslator
At the default compression level, the .abc size will be larger than .fbx about 40% but the both exporting/importing progresses will be much faster than the FBX format.
Here are some basic models from Mudbox, you may load it by my Mudbox plugin or put them into Maya and take a look.
Mar. 2
Compiled AbcTranslator by MSVC10 with Alembic 1.0.5 and boost 1.42 for Mudbox 2012 x64, you may DOWNLOAD from Ortholab.
BTW, Mudbox 2013 has been GOLD, the final version will be shipped soon, and I will supply built binary plug-in for it in future.
Apl. 8
Our Creative Suite 2013 has been released, you may download the binary plug-in for Mudbox 2013 x64 Windows.
最近开始在CentOS 6下修Mudbox的BUG，编译完毕了之后发现启动不了，猛然想起新系统没装NVIDIA的驱动，直接进入init 3后跑下载下来的驱动发现提示启用了Nouveau Driver，得先禁用之，下面的命令说明了如何禁用这个内置驱动的方法。
yum install gcc kernel-devel
reboot
重启了之后将Nouveau加入到黑名单，不加载之
sed -i '/root=/s|$| rdblacklist=nouveau vga=791|' /boot/grub/grub.conf
echo "blacklist nouveau" >> /etc/modprobe.d/blacklist.conf
修改initd
mv /boot/initramfs-$(uname -r).img /boot/initramfs-$(uname -r)-nouveau.img
dracut /boot/initramfs-$(uname -r).img $(uname -r)
移除Nouveau Driver
yum remove xorg-x11-drv-nouveau
reboot
重启后安装NVIDIA的官方驱动
init 3
sh ./NVIDIA-Linux-x86-260.19.29.run
