If there were a superman/superwoman I would expect him/her as benign to us as we to other life forms on earth or even towards one another historically.

Regarding good versus bad aliens, one of my most favorite movies is The Thing (1982), which I found to be much more convincing than E.T. The Extra-Terrestrial released in the same year.

While trying to draw a child, I realized that it would require shape and shading, which I have yet to master, in addition to contours, which I have been focusing on so far.
So I switched to a movie still that I liked a lot and is easier to draw from – a half covered face with plenty contours.

As an interesting coincidence, after finishing a privacy training I watched this movie.

The last one to watch the last Jedi?

Filed under: Real — liyiwei @ 10:02 pm

I finally watched the latest Star Wars movie on Sunday night. Avoiding spoilers is a good practice in discipline.

The movie is highly entertaining and has this tinge of smacking the tradition. But I still prefer the original series and even the prequels which are telling the background story of Darth Vader, the most important character of the entire Star Wars universe. The Force Awakens is refreshing, but I am not sure what The Last Jedi is trying to achieve in terms of the story line.

VR space warp is interesting and challenging enough, but VR time warp appears even more so.
At least I have no idea how to achieve that for the next SIGGRAPH project.

Ghost in the Shell

Filed under: Imaginary,Real — liyiwei @ 5:20 pm

There is a peculiar kind of pleasure for senior people to reminisce their junior experiences, as I discovered after getting older.

The first trailer closely matches the original anime, which is also available on Netflix.

Like many contemporary Japanese anime, the story can be confusing for people not familiar with the genre. But it seems quite clear from the second trailer, and different from the original story.

Race can be a sensitive issue for Hollywood, but watch how the Japanese react to the casting of this movie. This should be no surprise for people who understand the Japanese culture in general.

Double-edged sword

I found Bobby Fischer against the World a fascinating documentary about a particular kind of talent (chess) of a unique individual (Bobby Fischer, widely considered as the greatest chess player of all time who later self-destructed into an outcast) at a particular era (cold war, with chess being one of the competitions to showcase US/Soviet supremacy).

One interesting point pursued in the movie is about the specific type of brain that enables superior chess play may also cause certain psychological issues.
One can make a more general point in that unusual brains, as double-edged swords, can produce special talents as well as abnormal behaviors, as have been seen in geniuses across different disciplines such as musicians, artists, scientists, and mathematicians.

The matrix concert

I went to the Matrix in Concert with the San Francisco Symphony conducted by Don Davis, who is also the composer for the Matrix trilogy.

Basically, what they did is to play the first matrix movie with music accompanied by the orchestra.
I enjoyed the show for a variety of reasons: I am a fan of the original movies, the visual setup (black dressing + green lighting) is fitting, and the music integrates seamlessly with the movie.

The most interesting aspect is that the music adds (yet) another layer of performance + reality, over the original movie, which is already layered. The music starts with the opening scenes and ends after the end credits. So the entire show starts before the movie starts and ends after the movie ends. In a movie theater, most audience would walk out during the end credits, but we should sit through this one. (It was very funny to see a few folks who left during the end credits.)

What has not changed is that I want to be agent Smith if I can choose to become one of the characters.

Liberal art

Filed under: Imaginary,Real — liyiwei @ 6:40 pm

This is a random collection of thoughts after watching this movie, liberal arts, on a recent flight.

I like the movie; it is funny, informational, and the characters are cute (especially the one played by Elizabeth Olsen).

I finally got what it meant by liberal art college: basically, the kind of schools that trains one to be a generalist rather than for a specific profession. Quote from the movie: “I majored in English and minored in history just to make sure I am fully unemployable”.

I think computer science is some kind of liberal art: writing good codes is a lot like writing good proses, designing good algorithms is a lot like designing good plots, and making good UIs is a lot like making good plays!

From now on I am going to proclaim I do liberal art, in a more employable fashion.

I highly recommend this documentary, about a world renowned sushi chef achieving perfectionism. I agree with a lot of what he said, many of which are applicable for any profession.

My one word movie review: tensor.

Explanation: Inception is a layered version of The Matrix.

Overall, Dark City, The Matrix, and Inception are my 3 most favorite movies in this category.

Toon shading

Appleseed: Ex Machina is the best toon shaded animation I have ever seen. It really beats 2D cel animation.
I am too busy right now to write down more details, but just checkout this movie if you like anime or computer graphics.

Also, don’t miss the bonus features. I find it particularly interesting that the American crew talked about the “amazing collaboration” between Chinese (John Woo, producer) and Japanese (Shinji Aramaki, director) as though these two countries ought to start the third world war instead of collaborating on animation projects.

I watched this movie a few nights ago. It is about Genghis Khanโ€™s early life, between his childhood and his unification of the Mongolian tribes. I guess people might expect or want to see his more (in)famous later life for conquering the entire world, but that belongs to a (rumored) sequel. I actually prefer to watch his early life as that part is less well known.

The movie is unique in several aspects. The dialogues are primarily in Mongolian with occasional Mandarin. Mongolian sounds interesting, kind of halfway between Mandarin and Korean, even though the Mongolian spoken by most actors in the movie are not very authentic. (I have probably heard more authentic ones from real Mongols in Beijing airport.) The scenery is gorgeous, and in fact so difficult to film that the director has been thinking about cutting short or even canceling the sequels. The plot is a bit loose and incoherent, but the style nicely (and maybe coincidentally) reflects the mythological nature of Genghis Khanโ€™s early life and the nomadic Mongolian life style around that time.

The Mongols also possess certain historical fascination to me. The Chinese history books, authored primarily by the Han Chinese, naturally debased the Mongols (and any other ethnic minorities) as barbarians and describe their histories mainly as window dressings of the greatness of the Middle Kingdom. As far as I could recall I have never read a sufficiently accurate and non-biased recount of the Mongolian history. (The history text books authored by the Nationalist government in Taiwan around my time did not even recognize Mongol as an independent country.) This is sad, as the Mongols have made major impacts to world history and geography during their great conquering around the thirteenth century, however short living their empire was. As analyzed by certain historians (e.g. see False Economy: A Surprising Economic History of the World, by Alan Beattie), the Mongols could be responsible for the formation of dictatorship/authoritarian countries like Russia, Iran, and China, which were actually more liberal than the Europeans prior to the Mongolian invasion.

If I were a character in The Matrix, I want to be Anti-Neo who drags everyone from the real world back into the matrix. The synthetic world is so much easier to manipulate than the real one.

Waltz with Bashir

The phrase “animated documentary” may sound like an oxymoron, but that is exactly what I would use to describe Waltz with Bashir. I was originally attracted to this movie due to its graphics effects, especially on the masterful use of large regions of monotonic colors. What I did not expect was thought provoking storytelling, and I was thrilled to find plenty in this movie.

I highly recommend this movie, as well as the behind the scene bonus features on how the movie is made.

Renaissance is a stylish binary animation. By binary, I mean it is rendered in only two colors, black and white, not even gray scales which the movie used only rarely for special effects like transparency.


I watched this movie because it was mentioned in a research paper titled Artistic Thresholding, and I am curious about the artistic and technical effects. In particular, even though binary rendering has been performed on static images (e.g. posters), these are usually abstract renditions. Thus, it was not clear to me how the effect would carry over for 3D animations, for which frame-to-frame coherence is required in addition to single frame stylization.

Overall, the binary rendering of the movie looks very good, in terms of both intra frame stylization and inter frame coherence. The binary rendering, combined with the nature of the story line, pushes the film noir genre to the extreme.

In the bonus materials, the creators explained that the movie was authored as a combination of motion capture and 3D polygonal rendering. This is quite comprehensible. Unfortunately, no explanation was given to the binary shading part. From what I could see, no published research algorithms have achieved binary animation anywhere near what is shown this movie. The usual suspect is heavy manual work, but even with that I still cannot figure out how things were really done.

Looks like this is still a open research problem, and probably a darn hard one.

Being a romance/drama, Dolls is not my kind of movie, but I watched it nonetheless for the sake of family duty. It is a very interesting movie. At the time of viewing it is a bit slow and bland, but strangely the message gradually sinks in afterward. I guess it is like drinking some sort of wine that tastes gentle but with strong after effects.

This is all I am going to say about this movie, to avoid spoiler as well as the fact that I believe this movie is better to be felt than described.

A Scanner Darkly

Filed under: Imaginary,Real — liyiwei @ 1:26 pm
Tags: ,

A Scanner Darkly is a movie that I have wanted to see for a long time but somehow did not manage to do so until recently. And it turned out to be so good that I regret haven’t watched it earlier.

The movie depicts the world and life seen from the view points of a group of drug addicts. To convey the distorted views from these druggies with impaired perceptions and brain functions, the movie deployed not only the traditional story line and dialogues, but also a cartoonish, non-photorealistic rendering achieved by rotoscoping.
The combined effect is so realistically surreal (oxymoron?) and disoriented that for the first time I kind of be able to feel what it is like to be a druggie. Rotoscoping not only preserves the original acting, but also facilitates hallucinatory or science-fiction effects such as bugs crawling all over oneโ€™s body and the “scramble suit” that disguises an undercover’s identity by constant shifting through the difference appearances of millions of people.

And yes, like all good movies, this one has a great story as well.

I believe this is one of these movies that are so unique that it is going to hang in my head for a long time.
