### EASING.BI 0.6 [updated June 17th 2024]

Hi everyone.

I've just posted a little easing library on GitHub. It can be found here: https://github.com/guillaumerangheard/easing.bi.
It contains two classes. The first one (which is more of a type alias, really) is easing.equation. It's basically a function that takes a double and returns another double. All the classics are here: circular, cubic, exponential, linear (of course), quadratic, quartic, quintic, sine and smooth(er)step easing. The second class, easing.curve, emulates CSS's cubic-bezier. It takes four numbers (as doubles) : x1, y1, x2, and y2, corresponding to the curve's second and third keypoints (as the other two are implicit). Once you've created your curve, just call its .compute method (which takes a double and returns a double, and voilà.
Any and all feedback, criticism, and/or suggestion is of course welcome.
I believe the code is self-explanatory, but here's a little example:

Code: Select all

``````#include "easing/easing.bi"

using easing

print !"easing.equation:\n"
for i as double => 0d to 10d
print i, cubicInOut(i / 10d)
next i

print !"\neasing.curve:\n"
dim as curve c => curve(0d, .42d, .58d, 1d)
for i as double => 0d to 10d
print i, c.compute(i / 10d)
next i

sleep
``````

In easing.bi I have added an underscore to line 4.

Hi everyone.

Just a quick post to tell you that I just wrote a little manual for easing.bi.
Also, as for the next version, and for the sake of flexibility, I was planning to add the option to switch to single precision. How does that sound?

Cheers,

V.

Hi everyone.

I just posted an update. easing.curve's can now be exported to CSS and JSON (see https://github.com/guillaumerangheard/e ... /README.md).

Have a nice day.

Hi everyone.

I just updated easing.bi.
I refactored some of the code in the previous version, and added easing.back, easing.bounce, and easing.elastic.
I also added clamping to every function to make sure that t is always in the [0,1] range.

Have a nice day.
