How are 2D cartoons animated today?




Captain Ca


I understand how 3D images are made, they generate models and send them through animations. However, how do they do 2D cartoons? I asume they don't draw each individual frame anymore. But, backgrounds that don't move do appear to be hand-drawn in some shows. How do 2D cartoons go through animations?


Answer
Depending on the budget, deadlines, technology, experience and preference that 2D animations are made one way or another.

Small budgeted shows, destined for the weekly TV slots are mostly done on Flash these days. Characters are created from simple shapes with movable body parts (mouths, hands etc.) are pasted onto individual layers and animated individually or in concert with the other parts.

The good thing about Flash is that you can position key drawings (important, story-telling character poses of say, a hand) out and the computer will fill in the in-between drawings (all the other drawings between the key drawings to smooth out the movements) automatically. So you can position the hand at one location (a key), and then program the computer to move it to another location (another key) and it will fill in all the in-between drawings by itself (timing is done by the animator). Computers are only good at moving objects around perfectly and stretching/squashing them according to preset rules so you are limited to certain expressions. Of course, complex scenes still need to be animated by hand, but to keep the cost and the time consumed down, animators don't get to do them frequently, if at all.

You can recognize these shows by the extremely smooth movements exhibited by the characters, as well as the bold and uniformed outlines and colors throughout. Backgrounds can be painted by hand, either digitally or on papers( and then scanned into the computer), or created from bodies of static shapes and colors.

Bigger, movie-length animated films use specialized softwares, either developed in-house, or bought commercially like the Toon Boom Animation program. These, however, are almost completely hand-drawn (characters-wise), since you can only create good character animation when you have a feel of the lines and forms of the characters, a thing that is quite difficult to program on a computer.

Some studios use papers and scanners, some use graphic tablets like the Wacoms to imput drawings into their computers. Some parts of a character can be animated while others are put on a different layer and remain static.

You can recognize these films by the slight jittery outlines of the character when he/she/it moves, since each line was drawn to match up with the previous drawings', though never perfectly so, no matter how hard the animators tried. The backgrounds are usually painted by hand (either digitally or manually on papers), or in 3D models that mimic a particular style or both.

Having said all that, yes, most animated shows are still drawn by hand. Some are done on papers and scanners, some are done on computers with Wacom tablets, some combine both in the production process. 2D animation is a craft, and unless computers can draw imaginatively, animators will still have their jobs, drawing them lovingly frame by frame. I hope that helped.

what is realy ActiveX control?

I have realy problem with this messase whe i try to connect some web sites:(ur current setting prohibit running ActiveX control.as result the page may cannot be displayed.)
How can I escape from this problem?



Answer
ActiveX controls are software modules based on Microsoft's Component Object Model (COM) architecture. They add functionality to software applications by seamlessly incorporating pre-made modules with the basic software package. Modules can be interchanged but still appear as parts of the original software.

On the Internet, ActiveX controls can be linked to Web pages and downloaded by an ActiveX-compliant browser. ActiveX controls turn Web pages into software pages that perform like any other program launched from a server.

ActiveX controls can have full system access. In most instances this access is legitimate, but one should be cautious of malicious ActiveX applications.


ActiveX controls are components that add dynamic and interactive features to Web pages. With ActiveX tools, multimedia effects, animation, and functional applications can be added to Web sites. HouseCall, Trend Micro's online virus scanner is an example of the application of ActiveX.

ActiveX controls are typically installed with user permission. However, security measures can be circumvented. In some instances, ActiveX components in Web pages are able to run automatically when the Web pages are opened. Visiting users are also sometimes tricked into accepting unwanted ActiveX controls. The unauthorized installation and execution of ActiveX controls can open opportunities for malicious code to install components or to make modifications on visiting systems.


An ActiveX control is essentially a Windows program that can be distributed from a web page. These controls can do literally anything a Windows program can do. A Hostile ActiveX program does something that its user did not intend for it to do, such as erasing a hard drive, dropping a virus or trojan into your machine, or scanning your drive for tax records or documents. As with other Trojans, a Hostile ActiveX control will normally appear to have some other function than what it actually has.

This technology is used, among other things, to improve the functionality of web pages (adding animations, video, 3D browsing, etc). ActiveX controls are small programs that are inserted in these pages. Unfortunately, as they are programs, they can also be targets for viruses.
