    lottie vectors

    lottie vectors

    Create, display and process 2D vectors in a 3D window.

    Lottie Vectors is an application for Matlab that alows you to do some pretty neat things -with vectors. More exactly -displaying them in ways that hopefully will allow you to explore and better understand your vector data. The basic idea is simple, take a vector defined in one of a few different types of data formats and map it on the screen. Add another vector and you start to form a 'route'. Each route or position vector can be accompanied with a 'force' vector. This can be used to...

    TIM

    A raytracer for forbidden optics

    *** TIM's (now Dr TIM's) source code has moved to https://github.com/jkcuk/Dr-TIM *** TIM is a raytracer that was originally developed to simulate optical components called METATOYs, but it has since then developed into something much more general. Amongst other things, TIM can also calculate random-dot stereograms and anaglyphs and visualise ray trajectories.

    SPARTA

    Direct Simulation Monte Carlo (DSMC) Simulator

    SPARTA is a parallel DSMC code for performing simulations of low-density gases in 2d or 3d. Particles advect through a hierarchical Cartesian grid that overlays the simulation box. The grid is used to group particles by grid cell for purposes of performing collisions and chemistry. Physical objects with triangulated surfaces can be embedded in the grid, creating cut and split grid cells.

    datasw

    datasw, a tool for rapid processing of HPLC-SAXS data.

    Small-angle X-ray scattering (SAXS) in solution is a common low-resolution method which can efficiently complement high-resolution information obtained by crystallography or NMR. Sample monodispersity is key to reliable SAXS data interpretation and model building. Beamline setups with inline high-performance liquid chromatography (HPLC) are particularly useful for accurate profiling of heterogeneous samples. The program DATASW performs averaging of individual data frames from HPLC-SAXS...
