#TodayILeaned I can use #py5's #lerp (Linear intERPolation, also very much liked in #Processing & p5.js) function with #NumPy arrays (and why wouldn't it work, right?) I should write a post about this... I used to have a slow recursive function called lerp_tuple to interpolate between two polygons or collections of point positions and I can probably retire it!

I don't have time to go through the math now, but this looks pretty good. "Fixing the iterative damping interpolation in video games".

See also Improved Lerp Smoothing for a more thorough explanation of how to do the speedup lerp correctly (using exponential function). It also explains how to convert existing lerps with fixed values to ones using exp2() and deltaTime.

https://www.gamedeveloper.com/programming/improved-lerp-smoothing-

value = lerp(target, value, exp2(-rate*deltaTime))

With a rate of 1.0, the value will move halfway to the target each second. If you double the rate, the value will move in twice as fast.

Improved Lerp Smoothing.

Using value = lerp(value, target, speed) to smoothly animate a value is a common pattern. A trivial change can make it frame rate independent and easier to tune.

I thought this deltaTime video was well-done. It's a light-hearted look at getting mathematically correct results for changes over time with the opportunity to come up with your own answer before he explains. It completely avoids the "Fix your timestep" discussion and is all about writing gameplay code instead. https://www.youtube.com/watch?v=yGhfUcPjXuE

#Processing drawing infrastructure, out of the box, doesn't come with a "dashed line" primitive, or sophisticated line styles. Golan Levin and Tega Brain (Code as Creative Medium, 2021) propose writing a function for that as a small exercise. How to tackle it? How would you draw a dashed line if you only had a simple line() function for drawing?

My first intuition I think would be to use #lerp to get intermediary points along the line. I have often used some kind of "lerp tuple" strategy for coordinates. What would you do?
