It has been a long long time that I have not blogged in VRMath2 community site. From time to time, I still use the VRMath2 Editor to create 3D worlds for work and leisure. Since about 2018, I started using a tetrahedron as a model or visual representation of integrated STEM (science, technology, engineering, mathematics). I presented in the 2019 ICTE Conference, as well as in many classes to pre-service teachers. Finally in 2026, I created a 3D model of this to showcase some ideas about STEM integration.
