'tis impolite and quite a bit ungentlemanly to go overboard with compliments toward a Lady young of age.

@@chickenduckhappy agreed. chill out Matthew.

Fettes DoubleDislike für Matthew Winston ! 👎👎

some ppl got salty over your compliments lol

The people commenting here hating on your comment are ridiculous. Looks like they never left their moms basement.

are you gay?

@@commandershepard1944 he's talking about the work

@@commandershepard1944 wut?

@the nexus shes trans aint she?

Lol cry me a river, didn't know, don't care 😘

If I understand things correctly it's just the _map_ function that's provided in the Arduino framework. I've found this function so useful that I started using it in non-Arduino projects as well.

"She"? What "she"?

Lol turns out I'm not the only one who is rewatching haha

She's a bro

Mm, don't really understand what u mean. The graphics look clear and I can follow along easily.

Not that it matters much anyway. Most of your performance isn't being used on lerp

@@JasminUwU only if you use lerp whenever possible, which the talk is promoting

​@@devforfun5618you might also argue that in this case you'd want the numerically more stable convex-combination version she's shown in the talk

Figure something out

Ihkhihi

just skip the degree part and go work in a cafe or something

@@qqqq-dp4rv Well, just look at these right wing f(R)auds, high school drop outs to ivy league, leading part of the country. I don't think solving for the quadratic equation made a difference. We actually need cafe workers. That's not an insult.

it's a guy.

@FVRS I’m not kidding, it’s a trans guy. Look at his old videos and you will see.

@FVRS Are you questioning yourself yet? hahaha

@FVRS lol

@FVRS i mean, doesn t his voice make it obvious?

Same equation

So "a+t*(b-a)" and "(1-t)*a+b*t" are the two standard ways of implementing lerp. Mathematically, yes, they are exactly the same, but when running on actual hardware with IEEE 754 floating point numbers, they are /not/ necessarily the same! Why? Rounding errors. With the version Freya presented, for t=0 you are guaranteed to get back exactly a, and for t=1 you are guaranteed to get back exactly b. That is not the case with the simplified version. There you are only guaranteed to get back exactly a for t=0, but you are /not/ guaranteed to get back exactly b for t=1, due to rounding errors with IEEE 754 floating point values. That said, for the most part, especially with nice simple values for a and b, you will get back exactly b, and even if you don't, depending on your use case, it will be close enough to not matter. But that is why many developers prefer the version Freya presented.

@@Zguy1337 Thanks a lot :) it makes a lot of sense now. I'm like it wasn't that hard to see, why didn't she use a simpler way. But it still means we're performing less operations in the simpler method, aren't we? (my use case was games programming, mostly dealing with floats, though Unity already has a built in Lerp function)

from my custom library static public float Lerp(float t, float min, float max) => min * (1f - t) + max * t; // more robust computation of: min + t * (max - min) static public float InverseLerp(float lerp, float min, float max) { float denom = max - min; return denom.IsCloseToZero()? min : (lerp - min) / denom; } static public bool IsCloseToZero(this float value, float epsilon = 1E-6f) => Mathf.Abs(value) < epsilon;

@@krissloo143 "we're performing less operations in the simpler method, aren't we?" don't pay too much attention to it. if you don't believe me, benchmark it, it's practically negligible in terms of performance. multiplication is VERY fast.

Everyone DOES use these all the time, but the logic underpinning the techniques is seldom actually discussed. That's the point of the video, not to introduce lesser known techniques, but to explain the details of some commonly known techniques.

​@@DGFISH88 Unless the subject is how a quaternion is implemented i think most programmers also know whay say a lerp does internally.

@@erikm9768 a LOT of game programmers learn through doing, either starting with visual scripting in gamemaker and moving up to stuff like unity, and they won't know the fundamentals

Because that is
