Does any body know how to throw a ball so to speak? As in the image in 2D from one point to the other?

years ago i asked a young scholar this same question and he wandered off and came back ~1/2 an hour later with 4 pages of "work".

his eyes were intense and un-blinking (he'd just slain the beast, after all) as i took the pages and thanked him.

i wandered off (read "hid") and tried piecing it together. unable to make heads nor tails from it, i stuffed the notion deep under my mind.

now you've prompted me to revisit so i watched a series of (4) videos beginning HERE.

in short (from part 3):


(that's solving the angle with a given initial velocity)

i'll need to watch it again once my brain forgives me before attempting to code the functions, but it's a start? (unless someone's already done it... i should have searched before diving into the rabbit hole)

btw, IIRC correctly, the beginning of the series declares that this will not account for (air?) resistance (and, no wind). i expect that's a 10-part series.

I searched "ballistic" on the forum and it returns quite a few results. I haven't looked at any of them but there might be some gold dust amongst them.

A quadratic B├ęzier curve would solve the this, No?

Edit: fixed bug in code!

For even greater control of the curve arc, a Cubic Bezier curve (I like this one)
