I wrote https://github.com/EsportToys/TPMouse a while back with the “grid mode” that moves the mouse cursor by bisecting the screen coordinate incrementally.

You can trivially calculate the time-to-peak overshoot using the closed form equation. It’s the first (0-indexed) zero of the velocity response, i.e. happens at t = (pi / scale) And obviously it would only apply for the underdamped cas

A middleground is to use fixed timesteps with the closed form solution. Then the integration factors can be statically precomputed as constants, and every frame becomes just a 2x2 matrix multiplication. And even if you are to calculate the

It’s the general solution to a damped harmonic oscillator/mass-spring-damper system: m * x’’ + c * x’ + k * x = f(t) See https://web.archive.org/web/20230604215211/https://esporttoy...

Speaking of 2nd-order linear ODEs w/ const factor (a.k.a. mass-spring-damper systems), I wrote a blog post[0] deriving all possible general solutions in a concise matrix that makes it easily implementable in code. The following is the

Actuall you're missing ClipCursor as another way of moving the cursor. Also, mouse_event is just a wrapper around what's basically SendInput(mouse)

The friction/acceleration awkwardness can be solved by using a physically based timestep-independent formulation, which I implemented in TPMouse[0] and explained its derivation in a previous comment reply[1]. The gist of it is that the

And for Windows, my https://github.com/EsportToys/TPMouse was inspired by warpd itself but more focused on making direct cursor motion more usable using momentum.

Shameless plug, but you may like the Inertia Mode of my TPMouse script[0] if you need a keyboard-based workflow systemwide. [0] https://github.com/EsportToys/TPMouse

Try running the exe version with wine and see if it works on your system -- this uses only very old/stable WinAPIs so I'd imagine that wine would have it well-covered by now.

I use the G305 which is even more barebones in the buttons, however I remapped the dpi button to be a sort of "omnifunctional activator" that I combine Lua scripting from LGS with other Autoit scripting for accessing WinAPI to ach

Glad that you like it! You might also find my MouseTray utility useful (which I mentioned in another comment), since seeing from your bio that you're familiar with esports you might care a bit more about configurations.

I'm actually in the process of reworking it so that the keybinds can be fully remapped via a GUI. In fact, LibreScroll is my first step experimenting with multi-process delegation that will enable that functionality, since the current

Thank you! Another applet I made that I personally think is neat, although I see why it's not something many would care about, is the MouseTray[0] utility that gives me a quick "volume popup" but for mouse cursor speeds, it m

Thanks! It was actually inspired by rvaiya's warpd [0] which has a similar grid mode but with quadrants instead. I thought that needing to choose out of four quadrants at once is a bit overwhelming on cognitive load for something that

I'm curious about what you think of Hold mode vs Flick mode? I personally use Flick mode myself but thought that it might confuse the user on first-impression, so I have it default to Hold mode to be on the safe side.

Thank you for the kind words! I’ve never used Linux before, I wonder if it will work well with Wine since this script only uses very old WinAPIs, namely SendInput+RawInput+ClipCursor, and native win32 controls/tray, I would imagine tha

I highly recommend anything in Finite Element Methods, it gives you an immediate grounding to a concrete application. I personally really benefitted a lot in the following YouTube lecture series: https://www.math.colostate.edu&#x

I think the most common application is describing mesh connectivity in Finite Element Methods, where each entry in the matrix represents the influence each node has on each other. Basically any N^2 table can be constructed to describe the g

Fun fact: this is only valid for domains that have a notion of "selfness", i.e. that there is such thing as an "identity matrix" for the quantities. Consider the following square matrix: TSLA APPL GOOG MSFT
