Answer:
i'm not so much of an expert but i do know a thing or two. this is not the complete list since i'm not so involved in the actual animation industry and what goes on behind there. i still do animations the historical way for fun. stuff like flipbooks. but here it is
<u>current vs historical comparison</u>
- use of 2d or 3d art/modeling programs to graph movements and do character designs vs having to draw by hand, or mold by hand (clay stop motion etc) for everything
- the use of some modelling programs can automatically graph movements and you just have to make the character vs draw every frame or mold every fram of movement by hand, frames aren't produced automatically
- though some animators still prefer to use traditional/ historical ways, many are changing to the digital way because computers are a thing vs there's no stuff like computers
- colouring may be done digitally instead vs everything done by hand. this is getting redundant but they really had to do everything without computers
of course, there are more points but i think this is enough already. i recommend watching the asadora called "natsuzora" if you'd like to see historical animation in action. they show a lot about animations in the times with no computers. they show processes and also explain some steps to it. it's really nice!
<u>things that they have in common</u>
- i don't think there is anything else if the question is trying to ask what technologies that developed in the present time have something in common with the old. the whole point of separating current tech with old tech is because there is an upgrade. and the upgrade would not have super clear similarities to the olden. but even with the upgrade. the technology is meant to help with animation.
- like i said before, current tech is an upgrade from the old tech. for example, animation tables that have light at the bottom, currently may be equipped with more advanced functions that didn't exist in the old times
- but humans still need to be in charge of the making of animations. even if you use digital programs, people still have to monitor and make small changes because programs are not 100% perfect on its own. in historical times they did everything haha
<u>difference in tech</u>
- only limited to drawing with pencil on paper in olden times, but now you can also choose to draw with stylus on digital
- no computers, but now there are computers with softwares and stuff that helps with animation
- in current times, you can transfer files with computers and you can work anywhere. it can be transferred to different people at different places, even overseas. the olden times require you to be there
that's all that came up on the top of my head. hope it helped :)
