Open Source C++ Physics Software

MuJoCo, developed and maintained by Google DeepMind, is a high-performance physics engine designed for simulating complex, articulated systems that interact through contact. It is widely used in research fields such as robotics, biomechanics, computer graphics, animation, and machine learning, where fast and accurate physics simulations are essential. The engine provides a robust C API optimized for real-time computation, making it suitable for scientific research and advanced simulation environments. MuJoCo’s core architecture is performance-tuned and utilizes preallocated data structures created through an XML-based compiler. The platform includes built-in interactive visualization using OpenGL and a native graphical interface for analyzing and testing simulations. Additionally, it offers extensive utility functions for physics computation, Python bindings for developers, and a Unity plug-in to enable integration with game engines and visualization tools.

gVirtualXRay is a C++ library to simulate X-ray imaging. It is based on the Beer-Lambert law to compute the absorption of light (i.e. photons) by 3D objects (here polygon meshes). It is implemented on the graphics processing unit (GPU) using the OpenGL Shading Language (GLSL). SimpleGVXR is a smaller library build on the top of gVirtualXRay. It provides wrappers to Python, R, Ruby, Tcl, C#, Java, and GNU Octave.

ANNOUNCEMENT Project has moved to a proprietary website! http://www.instruman.it Updated source code available at https://instruman.codeplex.com/ This is an interface used to program and control Voltcraft DPPS-32-15 Power Supply, and to log data from Victor 86C Multimeter. It's an all-in-one solution to use the two instruments at the same time for Scientific, Research and Study purposes. Features avaible are the following: -Victor 86C USB HID connection protocol -86C data reading and logging -COM port selection -Continuous reading of Voltage and Current -Continuous logging of Voltage and Current in a Chart with the option to export data to csv file -Possibility to set logging rate from 50 ms -Turn ON and OFF instrument -Set Voltage and Current -Set a custom voltage loop to play and reiterate -Reiteration possible in three ways: for a fixed time, for a fixed number of cycles and until the STOP button is pressed

DIANNA (Diffraction Analysis of Nanopowders) is a free software developed to simulate atomic models of structures from an ensemble of nanoparticles and to calculate their whole X-ray powder diffraction patterns and the radial distribution function. The main objects of investigation are the particles whose coherent scattering domains do not exceed several nm. DIANNA is based on the ab initio method using the Debye scattering equation. This method makes it possible to obtain information on the atomic structure, shape and size of nanoparticles. It can be applied also to non-periodic materials or coherently ordered structures. How to use: 1. Unzip the archive. 2. Run the "Dianna_Startup.exe" file. 3. Use "Help" through the menu. Required: • Windows 7 or newer • Microsoft .NET Framework 4: www.microsoft.com/en-US/download/details.aspx?id=17851 (Web Installer, 1 Mb) www.microsoft.com/en-us/download/details.aspx?id=17718 (Standalone Installer, 48 Mb) • Microsoft Visual C+
