To remind, font2curves converts fonts to a list of uneven bezier curves* which can be directly rendered on the GPU. No atlases or fancy font rendering techniques required. *I provide the uneven bezier curve shader within font2curves

Above is based on: shadertoy.com/view/MlKcDD from @iquilezles

It can also be useful for cases where Hershey fonts are used, such as CNC machines and so on.

my dev machine will be an AMD Zen 4, so i'll be optimizing the physics core for AMDs now. This won't change things that much tho, back in the Zen 1 days, there were scheduling sequences that benefited Intel CPUs and were suboptimal for AMD CPUs. Nowadays these are rarer to find.

The problem is to find the rotation between two sets of corresponding 3d points. Luckily for me, i've created an algorithm that is simpler than above and only requires a quat and vector library, so i didn't had to implement a matrix library.

As an example, the game/gfx engine side is more biased towards matrix math whereas i don't even have a matrix library inside the physics core, i only use vector math. Physics vector math library is targeted towards performance, whereas game engine's one is more traditional. 2/3

The hardest filtering problem that we have is in our force feedback, as sim-driving is sensitive to response delay. I tested higher order IIR, kalman filters and others but they had delay or overshooting problems. We now use a 2nd order low delay filter, of my own devising.

On the other hand, Euler angles can safely roundtrip with rotation matrixes. Quaternions cannot. This is useful for save formats, if one doesn't want to generate unnecessary diffs on the version control system.
