Delta is a small toolbox/library to administer triangular meshes as they stem from CAD geometries and to do basic geometric checks such as collision checks. Delta’s objective is to do these operations fast on modern hardware. We call the project Delta as the code is written for triangles. If you type in \Delta in TeX, you get a triangle.


Delta is strongly influenced by research started by Konstantinos Krestenitis and Tomek Koziara under the umbrella of the project Frequency Response of Multibody Structures with Clearances and Validation of an Implicit Multibody Contact SOLFEC code. This project had been funded by EPSRC and EDF Energy (ICASE).

Later, we got support by EPSRC and Archer through the project Project Meshes (project no eCSE12-04).
