I understand that an ease-in-out curve starts slow, gets fast in the middle, and then ends slow. But what if I want the opposite of that? Starts fast, slow in the middle, ends fast? The reason is that I want to simulate a super-high jump. I'd like to use it but can't find any info about it because I don't know what it's called, and searching for "inverse in-out-ease" is not working out for me.
I'm sure people use this all the time on their websites but I just can't find any info on how to do it.
Thanks in advance.
