In short: get comfortable with vectors. The first thing you should do is write a simple vector class that does vector addition, subtraction, multiplication, dot product, cross product, and rotation. That’s all you need. The rest of your physics engine will be built atop vectors. Newton’s...
That’s not surprising- dot products and cross products don’t have a fast path. In fact, Vector3’s cross product is implemented in a completely scalar way. SOA Doofy is the ‘compute a single operation at a time and evict entire cache’ implementation noted in the SOA section. Not ...
For vectors * represents dot product, x represents scalar cross product (v1.x * v2.y - v2.x * v1.y). I also write +90deg to mean rotate a vector 90 degrees counterclockwise. Given object a with position Ra (vector), initial velocity Va, mass Ma, initial angular velocity Wa, ...
The infinitesimal work done by the resultant F of all the forces applied (including conservative forces and dissipative friction forces) to a point-mass of velocity v is equal to the dot product of that force into the displacement (v dt) of its point of application during a time dt. Namely...
