My program takes about 3 minutes to render the projectile motion image. Is this normal? Thanks!

It depends. But speaking generally, no, that isn't normal.

As a datapoint: a 900x550 "projectile motion" canvas takes about 1s to render on my Raspberry Pi 400 (not exactly a computational powerhouse).

If you post some code, maybe we can help?

Mmmm, that's good thanks for the reply. I'll have a look at my code and try to optimise it. If I can't figure it out, I'll post the code then

Edit: So, I just optimised it. I went from using strings to build up the ppm, to using a byte array. Strings are immutable in Go, so I was creating MANY of them! Renders super quick now.
