For example, our library enables software developers to visually assess the correctness of individual algorithmic steps, such as the 3D shape of a mesh deformation. This reduction in the difficulty of visualizing 3D information commoditizes the usage of a 3D scene. With our library, we empower the ImageJ scientific community to rapidly implement custom analytical tools for 3D/4D data sets, with a minimal investment of time and resources in handling the complex details of a hardware-accelerated 3D environment. Over the years, the scientific community has contributed a very large number of ImageJ extensions, known as plugins, which provide readily accessible implementations of numerous computer vision algorithms. Via ImageJ, our library has access to hundreds of biological image file formats. We have designed our library to enrich the core functionality of ImageJ (and its descendant Fiji ), an open source image processing application. Our library removes all the complexity of creating and interacting with image volumes and meshes in a 3D environment. We have created a software library for 3D/4D visualization, with functions for surface extraction, volume rendering and interactive volume editing. The application programming interfaces of existing packages range from the non-existent for most closed commercial solutions, to the very detailed and comprehensive open source VTK environment. While end-users benefit from well-documented, special-purpose commercial applications, the development of custom analytical tools is better handled by open source packages. These packages offer excellent solutions for the specific problems they were designed to solve.
Numerous image processing packages exist, either commercial (Amira, Visage Imaging MeVisLab, Mevis Imaris, BitPlane Volocity, PerkinElmer) or open source (VOXX, VTK and VTK-based applications such as Slicer3D, BioImageXD, and V3D UCSF Chimera VolumeJ and Volume Viewer ). We have identified a lack of accessible 3D/4D visualization software libraries for biological image processing. These libraries must provide (1) means to load and save any of the large diversity of image file formats (2) implementations for computer vision algorithms and (3) graphical user interfaces for data access by a human operator. The development of novel analytical tools is greatly facilitated by the existence of well-documented software libraries. In addition to the general requirement for visualization, the unique characteristics of each data set may demand specialized analysis. The first step in the analysis of biological image data is its visual inspection.

The acquisition of large three-dimensional (3D) data sets, often as time series (4D), has become the new standard. The number of images is exploding with the availability of high-throughput and high-resolution technologies. Images are the primary data of developmental and cell biology.

The Graphviz layout programs take descriptions of graphs in a simple text language, and make diagrams in useful formats, such as images and SVG for web pages PDF or Postscript for inclusion in other documents or display in an interactive graph browser. It has important applications in networking, bioinformatics, software engineering, database and web design, machine learning, and in visual interfaces for other technical domains. Graph visualization is a way of representing structural information as diagrams of abstract graphs and networks. Graphviz is open source graph visualization software.
