    Yeah, i was refering to building the fundamental equations, deriving all things in a left handed way and forgetting a - sign.

    Like the tensors for building the movement of rigid bodies in a left handed way, calculating jacobians, etc. The - signs start coming and don’t stop coming.

    I never built something on these abstractions, just made the equations themselves.

      It’s okay. The equations have been done since a long time ago. Devs don’t have to think about it much. Essentially, computer simulations already have their own body of math that you probably were not taught in physics, because they aren’t relevant for real world physics study.

        I did research in numerical calculus and physical simulations hahaha. Sound wave and polarized electromagnetic wave propagation in porous media.

          Yeah, and you probably used libraries that abstracted the math away so you could focus on your simulations instead of thinking about transforming negative signs for the GPUs. That’s already figured out.
