interactive physics simulation engine with vr too

youtu.be/4c-qngZI4PU like this you see in this engine we can play around with objects and fluids drop cubes into fluids and they will drown and result will be different if properties are changed and if collide two objects they will bounce off also we can test aerodynamics of our models and we can walk around our models and do some size estimates for 3d printing comparisons to get the right size or we can compare ourself to our model give it some weight and test its dynamics and then ride it if it crashs and breaks down then there is a mechanical also inclusion of programming too so we can program our own physics do some calculations so what im saying to be simple a place where physics exist our own programmed physics basically a sandbox of physics where we can test things out basically physics simulator and animate them
