CodeQuery is a tool for indexing and then querying or searching C, C++, Java, and Python source code. It builds upon the databases of cscope and ctags, which are processed by the cqmakedb tool to generate a CodeQuery database file. This can be viewed and queried with a GUI tool. The features include auto-completion of search terms and visualization of function call graphs and class inheritance. The following queries can be made: Symbol, Function or macro, Class or struct, Functions calling this function, Functions called by this function, Class which owns this member or method, Members and methods of this class, Parent of this class (inheritance), Children of this class (inheritance), Files including this file, and Full path for file.
DAE Tools is cross-platform equation-oriented process modelling, simulation, and optimization software. Various types of processes (lumped or distributed, steady-state or dynamic) can be modelled and optimized. They may range from very simple to those which require complex operating procedures. Equations can be ordinary or discontinuous, where discontinuities are automatically handled by the framework. Model reports containing all information about a model can be exported in XML MathML format, automatically creating high-quality documentation. The simulation results can be visualized, plotted, and/or exported into various formats.
ECM is demo software for planetary-scale terrain rendering. It implements Ellipsoidal Cube Maps (ECMs), as described in M. Lambers and A. Kolb, Ellipsoidal Cube Maps for Accurate Rendering of Planetary-Scale Terrain Data, Proc. Pacific Graphics (Short Papers), Sep. 2012. It consists of three parts: libecmdb, which implements the basic model and projection; ecmdb, which builds ECM databases from remote sensing data; and ecmview, which renders ECM databases interactively.
Genius is an arbitrary precision integer and multiple precision floating point calculator. It includes its own programming language similar in some aspects to C, bc, or Pascal. It can deal with rational numbers and complex numbers. It has matrix support as well. It uses the gmp library so it is very fast for calculations of large numbers. It has a command line and a GNOME interface. The GNOME interface supports plotting functions and 3D surfaces.
Gerbil consists of an interactive visualization tool targeted at multispectral and hyperspectral image data, and a toolbox of common algorithms, e.g. for segmentation. Multispectral imaging has been gaining popularity and has been gradually applied to many fields besides remote sensing. However, due to the high dimensionality of the data, both human observers and computers have difficulty interpreting this wealth of information. Gerbil facilitates the visualization of the relationship between spectral and topological information in a novel fashion. It puts emphasis on the spectral gradient, which is shown to provide enhanced information for many reflectance analysis tasks. It also includes a rich toolbox for evaluation of image segmentation and other algorithms in the multispectral domain. The parallel coordinates visualization technique is combined with hashing for a highly interactive visual connection between spectral distribution, spectral gradient, and topology.
Hypercube is a graph visualization tool for drawing DOT (graphviz), GML, GraphML, GXL and simple text-based graph representations as SVG and EPS images. It comes with a Qt-based GUI application and a Qt-independent commandline tool. Hypercube uses a simulated annealing algorithm to lay out the graph, which can be easily parameterized to achieve the desired look.
