A simple tool for the visualisation of coarse-grained systems
cogli2 (formerly known as cogli1) is a simple tool to visualise configurations of coarse-grained simulations. It is straightforward to use and it has a few features that make it very handy to produce publication-ready figures. It supports its own file format but implementing additional parsers is fairly easy. As of now it is not well documented, but this is something we will improve upon in the near future.
Demonstrates a quadtree for spatial indexing of triangles
This C++ demo allows users to interactively explore a quadtree's behavior.
For this purpose the demo uses a quadtree data structure based on axis-aligned bounding boxes to speed up the search for triangles in a mesh. Depending on a search point all triangles of a quadtree's region are retrieved and relevant information about the search is shown.
Quadtree creation can be parametrized by three parameters:
- Maximum tree depth.
- Maximum number of triangles per region.
- Percentage...
