I watched this movie wearing 3D glasses. (It might be good to say which movie in the sentence, and when)

The photo in the middle is of the 3D glasses. (In English, we take pictures "of" things. So for example "I have a picture of you.")

It was a bit annoying to wear them throughout the whole the movie, but the 3D images were amazing.

At that time, we had to wear a cheap paper glasses with blue and red cellophane in order to see the 3D images.

However, even though I wore them, I couldn't see in 3D. (I'm not sure what you mean by "I couldn't realize 3D")

Now that I think about it, the technological advancements have been tremendous.

As you know, in this movie, a technology called "performance capture" is used.

Actually I don't like how humans are presented by it.

They are like dolls that are too human-like. (Often in English it is easiest to just say _____-like to describe something).

I feel like I don't know about 70% of all the words in the book. (We usually use "I feel that..." when saying an opinion. For example, "I feel that we should give money to the poor.")

Does Charles Dickens tend to write with some difficult words?

The photo in the middle shows the 3D glasses which I wore.

However, even though I wore them, I couldn't see them in 3D.

I think we will be able to see 3D images without glasses sometime in the future.

Does Charles Dickens tend to use words which are a bit too difficult?

However, even though I wore them, I couldn't feel that it was three-dimensional. (もしかして、その眼鏡をかけても、３Dに感じることができなかった）

It was a bit annoying to wear them throughout the whole movie, but the 3D images were amazing.

When I was a kid, "The Wizard of Oz" was on TV in 3D.

At that time, we had to wear the cheap paper glasses with blue and red cellophane in order to see 3D images. Jean's corrections for this sentence are fine also.

In this movie, the technology called "performance capture" is used. This sounds fine as written. Except I didn't know it.. I'm not as smart as you, :o*

Actually I don't like the way it makes humans look. I don't like changing your sentence so much, but this is the most natural way to say it. In this context, "look" means "appear"

They are like dolls that are too much like humans.

At that time, we had to wear a cheap paper glasses made with blue and red cellophane in order to see the 3D images.

As you may know, in this movie a technology called "performance capture" is used.

They are like dolls that are much too human looking.

S-s-scary!!(if you want to express stuttering (どもり？) then using dashes (the '-' symbol) would be better)　

However, even though I wore them, I couldn't realize see anything in 3D.

Now that I think about it, the technological advancements since then have been is tremendous.

As you may know, in this movie, the a technology called "performance capture" is used.

Having to wear them for the whole movie was a bit annoying, but the 3D images were amazing. (offering a different, more natural wording)

Back then, we had to wear a cheap paper glasses with red and blue cellophane in order to see 3D images/the movie in 3D. ("At that time" is often used by Japanese [そのときに], but "back then" sounds better to me. For some reason, "red and blue" sounds better in that order -- I asked 2 other people.)

Suggestion: As you may know, this movie was made using a technology called "performance capture".

Actually, I don't like the way humans are rendered with this technique. ("render" refers to the process that creates human-like creatures in the making of the movie)

Does Charles Dickens tend to use difficult words?

It might just be because of my poor vocabulary. (this is the right order)

I watched this movie wearing 3D glasses.

However, even though I wore them, it didn't really look 3D.
