## SPlisHSPlasH

SPlisHSPlasH is an open-source library for the physically-based simulation of fluids. The simulation in this library is based on the Smoothed Particle Hydrodynamics (SPH) method which is a popular meshless Lagrangian approach to simulate complex fluid effects. The SPH formalism allows an efficient computation of a certain quantity of a fluid particle by considering only a finite set of neighboring particles. One of the most important research topics in the field of SPH methods is the simulation of incompressible fluids. SPlisHSPlasH implements current state-of-the-art pressure solvers (WCSPH, PCISPH, PBF, IISPH, DFSPH) to simulate incompressibility. Moreover, the library provides different methods to simulate viscosity and surface tension.

Features
• Fluid simulation based on Smoothed Particle Hydrodynamics (SPH)
• The library implements state-of-the-art pressure solvers (WCSPH, PCISPH, PBF, IISPH, DFSPH) to simulate incompressibility
• Simulation of viscosity

## PositionBasedDynamics

This library supports the physically-based simulation of mechanical effects. In the last years position-based simulation methods have become popular in the graphics community. In contrast to classical simulation approaches these methods compute the position changes in each simulation step directly, based on the solution of a quasi-static problem. Therefore, position-based approaches are fast, stable and controllable which make them well-suited for use in interactive environments. However, these methods are generally not as accurate as force-based methods but still provide visual plausibility. Hence, the main application areas of position-based simulation are virtual reality, computer games and special effects in movies and commercials.

The PositionBasedDynamics library allows the position-based handling of many types of constraints in a physically-based simulation.

Features
• Physically-based simulation with position-based constraint handling.
• Library supports many constraints: point-point, point-edge, point-triangle and edge-edge distance constraints, dihedral bending constraint, isometric bending, volume constraint, shape matching, FEM-based PBD (2D & 3D), strain-based dynamics (2D & 3D), position-based fluids and position-based rigid body dynamics.
• Simple interface
• Demos
• Library is free even for commercial applications.

## CompactNSearch

CompactNSearch is a C++ library for parallel computation of neighboring points in a fixed radius in a three-dimensional point cloud. The implemented algorithm is a variant of the Compact Hashing approach proposed by Ihmsen et al. The neighborhood information can be efficiently updated when the points spatially move. Moreover, the library offers the possibility to reorder the points (and other array-stored per point information) according to a space-filling Z curve to improve the cache efficiency in later queries or accesses.

This is just a small Latex Add-In for PowerPoint. It enables to add and edit Latex equations or symbols in a PowerPoint slide easily. The Add-In is based on ScintillaNET and supports syntax highlighting, code snippets etc.

With the add-in you can open a dialog, enter something like $y = \sum_{i=0}^n x_i$ and you will get an equation in your slide. This is done by embedding your Latex code in a template. Then, latex.exe is called in order to create a DVI which is afterwards converted in a PNG file by Ghostscript. The PNG is then inserted in your slide. Your Latex code is stored in the genertated PowerPoint object. Hence, you can edit your code later.

## Tex & Paste

Tex&Paste is a small tool which translates your Latex code to generate an image in the clipboard. This means you can directly paste the resulting image in applications like Powerpoint, CorelDraw or Illustrator. Tex&Paste enables you to add Latex equations or symbols in any application that can handle images easily. The tool is based on ScintillaNET and supports syntax highlighting, code snippets etc.

Using Tex&Paste you can enter a Latex equation easily and you will get an image of this equation in your clipboard. This is done by embedding your Latex code in a template. Then, latex.exe is called in order to create a DVI which is afterwards converted in a PNG file by Ghostscript. The resulting image of the equation can be pasted in applications like Powerpoint, CorelDraw, Illustrator, Inkscape etc.
