digital wizardry in the dream factory - touch screen digital picture frame

The success of "youth school" depends largely on Ang Lee's performance, and Ang Lee won his second Oscar for best director with his second protagonist
Richard Parker, Bengal Tiger
The director, of course, did not tame a fierce creature to get an extraordinary performance, but instead found the right team to revive the tiger on a 3D screen.
The sequence about the tiger involved was generated by the visual effects company Rhythm & Hues computer.
In fact, nowadays, the amazing scenes in Hollywood movies are often generated by computers.
So how do these real computer graphics come into being?
About 600 artists from the rhythm and hue team spent hundreds of hours working together the visual effects of the Bengal tiger and other flashing graphic sequences in Pi's life.
Unlike Shrek, Kung Fu Panda and other films, Lee Kai-Fu's Oscar-winning film is not strictly animated, but uses a large number of computer graphics;
Scene action lens as the basis.
For example, in a scene involving boys and tigers on board, the live action captures the boys and the boat, but the tiger is pasted into the scene by the visual effects team.
At the first level, computer graphics are like drawing comics.
The original design was drawn by artists, not on paper, but on the digital slate.
Digital artists draw the first form using tablets such as Samsung's 7-series tablet or iPad.
Touch screen displays capture artist strokes through digital pens and store them in digital format, which are further enhanced through Adobe's After Effects or using tools such as specialized program processing.
Proprietary tools Maya and free software Blender can also create computer graphics directly on the software platform.
This method is used when the whole landscape or character is to be created independently, just like most animated movies.
The miracle of 3D is not only the sunglasses worn when watching movies.
Making 3D movies has its own complexity.
When we look closely at an object, each eye sees something extra (
Verify this by looking at an object with only one eye at a time).
This difference provides 3D or stereo vision for humans.
So, the trick to making a 3D movie is to use two different lenses to capture the scene, which are very small apart, like the human eye, or to replicate similar effects by using computer-generated images.
3D glasses isolate these two captures and provide a slightly offset visual feedback to each of our eyes to convince our brain that we see it in 3D.
Using sophisticated software can make this creation look real, but if Richard Parker doesn't look wet when he jumps into the water, no matter how realistic the tiger looks, digital artifacts still seem unconvincing.
Simulation of physics with good fidelity is a key aspect of achieving special effects.
Rhythm and hue seek the help of researchers in the Department of Applied and Computational Mathematics at California Institute of Technology to model the tiger's response mathematically.
This complex mathematical model is applied to the digital tiger, which can roar, pounce, jump and swim like a real tiger.
Once the graphic content and physics are ready, combine the art with the behavioral model in the scene.
This is often referred to as "rendering ".
This step requires a lot of calculations.
Pi's life is shot at 48 frames per second, which means we will be watching 48 real high resolution images in a second.
Render each of these frames in 127-
The minute movie requires a lot of computing power. A single high-
The terminal computer is not enough even the server.
Nowadays, movie rendering uses computer grids, and cloud computing services are increasingly used.
For example, using Intel's DreamWorks
The power Xeon processor rendering movie "Kung Fu Panda" running the cloud server takes 55 million hours of rendering time, which is executed in parallel on multiple CPU cores in the cloud.
It takes a lot of work to make a movie, not an actor's performance, but a better opportunity for technology to bring you an unforgettable movie experience.
