Source code for GJK collision detection project during the course DH2323 Computer Graphics and Interaction.
This is the .dll code, in a Visual Studio 2019 project, used for https://github.com/frilel/GJK_tester. See https://docs.unity3d.com/Manual/UsingDLL.html under the heading “Create a DLL with Visual Studio” for how to create a .dll to use in Unity. Or just grab it from the GJK_tester/Assets/Plugins/CLCollision.dll.
