What Is CGI And How Does It Work?

If you like a big budget Hollywood movie, then this one is for you. You've probably heard about CGI so many time and just like you know, Hollywood movie use a lot of CGI and it was awesome. Sometimes, you can't tell the difference between the real one and the CGI. But did you ever stop and think what is CGI exactly? Who invented it? and mostly, how does it work? We will get there.

But first, did you know what CGI stands for? According to Wikipedia, CGI stands for Computer-Generated Imagery. So that means all of the 3D animation that you see on the movie, was made by computer. CGI was used for everything not only a movie, but it was also used in a Video Game, Commercial, Television Show, Animation, etc. In Video Game, CGI technology used at the cut scene and trailer. But in movie, CGI is mostly used for create a fantasy character like elf, dwarf,etc. And also for create a monster like in Pacific Rim or giant robot like in Transformers. But some movie, use CGI to make a superhero suit like Iron Man.

Well if we are talking about CGI, it's never far from the animation world. In fact, today's cartoon also used CGI to smooth the character movement. The first animation was produced in 1901 and created by a man named Walter Disney. He build a famous animation company called Walt Disney, at first Walt Disney is not so popular. But because of the Walter Disney's persistence, Disney become more and more famous. And because of that, many people try to do the same thing. So many animation or cartoon began to popping up like Tom and Jerry, Looney Tunes, The Simpsons, etc. And finally, in June 1976 CGI animation was invented. Since then, CGI become more sophisticated and look like it was real.

How Does It Work?

There are two type of CGI, 2D and 3D. Just like I said before, 2D CGI is used in cartoon while 3D CGI is used in today's movie. They used it to create objects with real shapes, lighting, textures, even the object can move as if were alive. So many applications that you can use to make CGI, like 3DS Max, Blender, Light Wave 3D, Maya, and Autodesk Softimage.

Even though the CGI was invented in 1976, CGI has been used in the movie Westworld that came out in 1973. But it was only 2D, so the CGI isn't very good and not as sophisticated as now. And it looks like an ordinary animation. Take a look at this picture, if you want to know how CGI works.

Twilight
There's no way Kristen Stewart is petting a real giant wolf. They make a wolf on the computer, then replace the person with the wolf they had made earlier. If  that was a real wolf, She will be dead by now. Well, at least that guy is having the best time of his life.

Doctor Strange
As you can see, the portal that Doctor Strange made was actually a giant circle made from neon lights (or maybe that was a hulahoop). Basically they just replace the giant neon circle with a portal and then add some effect to make it real.

Guardians Of The Galaxy
This scene is the same with the scene in Twilight movie earlier. They replaced that poor guy with a talking racoon. That guy will never sleep well at night.

Man Of Steel
In this movie, the superman is not really flying. As you can see here, that guy is pretending like what every normal actor do. They just add a background and wind effect to his cape. If he was really flying, CIA office will be busy right now.

Iron Man
Like every superheroes movie, the suit in that Tony Stark had is just a CGI. In real life that guy is just wearing a special shirt and the only one that real was the helmet.

And that is how CGI works, with the technology that keep growing. I'm pretty sure that real actors will not be needed in the future. Every actors that we see in the movie are animation, and the only thing that was real is the film crew.

How To Eliminate Malware From Your Computer

Last time I already give you an article about how to eliminate spyware. And this time, I'm going too give the same article. But, in this article, we're gonna talking about how to remove malicious software or malware from your computer. 

Sometimes virus can be dangerous for your computer. You can loss some of your files or maybe worse, you can't open your application or data. But malware in the other hand, is far more scary. Your computer can be infected by malware, if you try download or install an application that has been cracked. Sometime they add a malicious application inside an application that you want to download. So that's why you better buy the application that you want to download from the developer itself. But still, you have to be careful when you are about download something on the internet.

Anyway without further ado, let's just go with how to eliminate a malicious software from your computer. But before that, I'm just gonna remind you that I only give you how to eliminate malware for windows only.

Use Offline Scanner
Did you know that windows 10 have a tool that allow you to eliminate malware? Yes, and it's called Windows Defender Offline. It's called offline because Windows Defender doing scanning outside of Windows. So the process of scanning and cleaning the malware is done before you go into Windows.

Well, It's easy to run it. Just go to Settings> Update & Security> Windows Defender> scroll down and select Scan Offline. After that Windows 10 will automatically restart and offline scanning process will start. The process will last 15 - 20 minutes and automatically enter Windows once the entire process is complete.

Update Your Anti Virus
This is the basic thing you should do, always update you anti virus definition. Otherwise, your computer will be vulnerable to virus or malware attack. Because just like the technology that always evolving, computer virus and malware will always evolved and become more dangerous.

In that case, you should evolve your anti virus by updating it. To do this, you will need an anti virus. And then open your anti virus, find the update button and click it. That way, you will be protected against all of the virus and malware that will attack your computer.

Clean The Temporary Files
Temporary files, including cache and cookies on the browser often become the nesting place of malware. For that, clean the temporary file on the browser, as well as windows (including the recycle bin) if you want to remove malware from your computer. To delete temporary files in windows, go to RUN then type % temp%. Delete all the contents of the temporary file.

Then remove the contents of the recycle bin, and then right click on the recycle bin icon on the desktop and select empty recycle bin. To delete temporary files in the Chrome browser, go to history, click menu and then select the option to delete browsing data. Check all options to delete all data.

Delete / Reset System Restore
Windows also has a System restore feature, which is actually very useful if there is a problem with the system. With system restore we can restore the system back like when point restore point in save. But unfortunately system restore is also often used as the safe house for malware.

I personally prefer to turn off all system restore. To reset system restore is quite easy, you just need to turn off system restore then turn off computer. After that restart the system restore, then the previously saved file system has been removed and replaced with the latest one.

Reinstall Your Computer
This is the last way and probably the most powerful way to remove malware from your computer. With a note, other partitions besides file system must also be scanned first, so it will not infect your computer system again. But too often re-install the OS also gives a bad impact, so you should be careful here.

So it's all up to you. If you are not careful enough, you will break your computer and probably lose all of your data and files. And just for your information, Most malware attacks the Windows OS, while other OS including Linux is very rarely attacked because of its open source nature that makes linux has a pretty tough security system. So there is no harm in switching to the program and Open Source Operating System. Or if you didn't like linux, you can use Apple Mac Computer that never attacked by virus.
