Vaa3D is a cross-platform (Mac, Linux, and Windows) tool for visualizing large-scale (gigabytes, and 64-bit data) 3D/4D/5D image stacks and various surface data. It is also a container of powerful modules for 3D image analysis (cell segmentation, neuron tracing, brain registration, annotation, quantitative measurement and statistics, etc) and data management. Vaa3D is very easy to be extended via a powerful plugin interface. For example, many ITK tools are being converted to Vaa3D Plugins. Vaa3D-Neuron is built upon Vaa3D to make 3D neuron reconstruction much easier. In a recent Nature Biotechnology paper (2010, 28(4), pp.348-353) about Vaa3D and Vaa3D-Neuron, an order of magnitude of performance improvement (both reconstruction accuracy and speed) was achieved compared to other tools. 2010-6-24 Production/Stable v2.475 2010-5-14 Production/Stable V3D 2.466, V3D-Neuron 2.0, Plugin Interface 0.92 Vaa3D and Vaa3D-Neuron Win32 (MS Windows), Gnome, KDE, Other Environment, V3D License 2010-April, English, Production/Stable, Windows NT/2000, C++, Shape Analysis, Windows Vista, Other Audience, Developers, End Users, MacOS, Linux, C, Cygwin, Windows 95/98/2000, Windows XP, Atlas Application, Segmentation, Resampling, Warping, Registration, Surface Analysis, Other Format, Image Display, Position, Volumetric Analysis, Neuronal Characterization, Fiber Tracking, Platform or Development Environment, Algorithm or Reusable Library, Rendering http://www.nitrc.org/projects/v3d/, http://www.vaa3d.org v3d.list@gmail.com
