MegaMol is a visualization middleware used to visualize point-based molecular data sets. This software is developed within the ​Collaborative Research Center 716, subproject ​D.3 at the ​Visualization Research Center (VISUS) of the University of Stuttgart and at the ​Computer Graphics and Visualization Group of the TU Dresden.

MegaMol succeeds ​MolCloud, which has been developed at the University of Stuttgart in order to visualize point-based data sets. MegaMol is written in C++, and uses an OpenGL as Rendering-API and GLSL-Shader. It supports the operating systems Microsoft Windows and Linux, each in 32-bit and 64-bit versions. In large parts, MegaMol is based on VISlib, a C++-class library for scientific visualization, which has also been developed at the University of Stuttgart.

1. Clone the MegaMol repository

2. Create a build folder

3. Invoke cmake inside the build folder

4. Execute make to build MegaMol

5. Run make install to create your MegaMol installation

6. Test Megamol with

    ./megamol.sh -p ..\examples\testspheres.lua
   

1. Clone the MegaMol repository

2. Use the cmake GUI to configure MegaMol

3. Open the generated sln file with Visual Studio

4. Use the ALL_BUILD target to build MegaMol

5. Use the INSTALL target to create your MegaMol installation

6. Test Megamol with

    mmconsole.exe -p ..\examples\testspheres.lua
   

MegaMol offers a configurator GUI (C#) that runs with .Net Framework 4. It runs also on Linux with Mono 3.2.8 (except for the analysis function and indirect-start functions).

are located in the projects folder in the source directory of MegaMol. To run the project in MegaMol, run one of the following commands from within the projects folder:

path/to/mmconsole -p "topoinvis_buoyant_I.mmprj" -i TopoInVis_(Buoyant_I) inst
path/to/mmconsole -p "topoinvis_buoyant_II.mmprj" -i TopoInVis_(Buoyant_II) inst
path/to/mmconsole -p "theisel.mmprj" -i Theisel3D inst

Using the GUI, you can modify the parameters, run the computations, and visualize the results. To just load the results provided in the data folder, expand ::inst::implicit_topology1 in the GUI, press the load_computation button, and follow up by starting the computation by clicking on start_computation.
