Understanding The Difference Between 2D And 3D Animations

You have no doubt heard the term “animation” and the technical definition is the filming of a sequence of positions or drawings to create an illusion of motion. With the advent of computers, animation evolved from hand drawings to perhaps the most recognized forms of computer 2D animations and 3D computer animation. While the entertainment industry continues to create amazing computer generated 3D animations, what used to take a great deal of manpower, not to mention pencils, cels, etc. can now be accomplished by a single individual.

The most familiar form of 2D animations can be found by watching Saturday morning cartoons with your kids, or even simpler animations every day when you surf the web. It takes on the forms of advertisements, e-cards, etc. The basic starting point for all animations is a storyboard that lays out the basic script in a visual format, much like an extra large comic strip.

From that point a rough audio track of the script is created to give animators something to sync with their drawings. This form of animation uses “vector graphics,” meaning that the images are based upon mathematical equations, rather than by an array of pixels, such as in “raster graphics.”

Although similar in some ways to 2D animations, 3D computer animation is a different process, as a scene being done in 3D is created long before any actual animation begins. Even in general terms, most people automatically think 3D when they are speaking or reading about computer animation, partly due to its flexibility.

What many people do not realize is that the entertainment industry and specifically motion picture applications, while possibly being the forerunners in advancing technologies, only account for a fraction of the 3D animations market. Actually, there is very little difference between computer animation and what is called traditional animation.

The main difference is the tools that are used to create animations, the effort and the price. Traditional 3D animation was more like claymations, and was done by using stop-motion filming techniques. Essentially, the true concept of 3D animations did not really catch on until the use of computers for animation became more cost effective and practical.

Although the entertainment industry is largely responsible for the advances in 3D computer animation, they make up only a small part of the market that uses 3D animations. Animation designs sell products; it is also used as a teaching aide because it presents information in a more understandable way.

Many animations can be created completely on a computer, but depending on the type of animation desired, such as cartoon animations, there may be the need for some hand-penciling work to be done.

A whole world of information about 3d computer animation eagerly awaits you from Mike Selvon portal. We appreciate your feedback at our computer animation design and production blog.

Windows Vista: Time Servers, Synchronisation and Time Zone Advice

It can be really annoying. You have just got off the plane, booted up your lap top and set the clock to local time. Yet all your appointments suddenly move, not just the ones on that side of the ocean either, when you return home and reset the clock the appointments refuse to go back.

This problem occurs because of the way a computer handles time. In general computers ignore time zones and base their time on UTC (Coordinated Universal Time) the international time standard.
Time can cause havoc with computers, not just with lap tops either. Computers all over the world need to be telling the same time particularly if they have to perform time sensitive transactions or need to keep their networks secure.

Most computer networks use NTP servers (Network Time Protocol) to keep synchronized.NTP time servers use an UTC timing reference either from the Internet or from a radio or GPS transmission. A UTC timing reference originally comes from an atomic clock and is as accurate as humanely possible.

When travelling abroad it is good advice NOT to adjust the system clock as your computer (and its associated programs such as Outlook) stores all time in UTC form and only offsets for a particular time zone (So in France the time is UTC+1 while in the US (EST) it becomes UTC-6.

However there are several features on Windows Vista that can make keeping track of the time a lot easier for travelers.

To keep track of the time zone you are travelling to, windows Vista can display more than one clock in the task bar (up to three).

To enable multiple clocks to be displayed simply double click on the time display in the system tray (bottom-right corner), click the’ change date and time settings tab’ to bring up a date and time” dialog box, click Additional Clocks tab, tick the check-box of Show this clock, select the time-zone of the clock, enter the display name and click OK button.

Next time your mouse pointer goes over the system tray your new clock should be displayed besides the original (which should be larger).
The clocks can also be placed on the Windows sidebar although this can use precious processing power.

Another useful application in Windows Vista is being able to synchronise the system clock with a UTC time source.

Vista already comes equipped with a NTP service called Windows Time Service (w32tm.exe) which can synchronise to a UTC time source over the Internet. To do this merely double click on the clock in the system tray and await the Internet Time tab. Click it an enter the name of the UTC server you wish to connect to (such as windows.time or nist.gov).

Vista can handle daylight savings time too. If the system clock (the main one not additional ones) is set to adjust for daylight saving then the computer should automatically do it. However it must be noted that some countries in the same time zone do not practice daylight saving hours so the correct time should always be double checked.

Configuring Windows 2003 to run as a NTP Network Time Server

Time synchronisation in modern computer networks is essential, all computers need to know the time as many applications, from sending an email to storing information are reliant on the PC knowing when the event took place.

Microsoft Windows Server from 2000 onwards has a time synchronisation utility built into the operating system called Windows Time (w32time.exe) which can be configured to operate as a network time server.

Windows 2003 Server can easily set the system clock to use UTC (Coordinated Universal Time, the World’s time standard) by accessing an Internet source (either: time.windows.com or time.nist.gov). To achieve this, a user merely has to double click the clock on their desktop and adjust the settings in the Internet Time tab.

It must be noted however, that Microsoft and other operating system manufacturers strongly advise that external timing references should be used as Internet sources can’t be authenticated.

To configure the Windows Time service to use an external time source, click Start, Run and type regedit then click OK.

Locate the following subkey:
HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesW32TimeParametersType
In the right pane, right-click Type then click Modify, in edit Value type NTP in the Value data box then click OK.

Locate the following subkey:
HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesW32TimeConfigAnnounceFlags.

In the right pane, right-click AnnounceFlags and click Modify. The ‘AnnounceFlags’ registry entry indicates whether the server is a trusted time reference, 5 indicates a trusted source so in the Edit DWORD Value box, under Value Data, type 5, then click OK.

Network Time Protocol (NTP) is an Internet protocol used for the transfer of accurate time, providing time information along so that a precise time can be obtained
To enable the Network Time Protocol; NTPserver, locate and click:

HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesW32TimeTimeProvidersNtpServer
In the right pane, right-click Enabled, then click Modify.

In the Edit DWord Value box, type 1 under Value data, then click OK.

Now go back and click on
HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesW32TimeParametersNtpServer

In the right pane, right-click NtpServer, then Modify, in the Edit DWORD Value under Value Data type In the right pane, right-click NtpServer, then Modify, in the Edit DWORD Value under Value Data type the Domain Name System (DNS), each DNS must be unique and you must append 0×1 to the end of each DNS name otherwise changes will not take effect.

Now click Ok.

Locate and click the following
HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesW32TimeTimeProvidersNtpClientSpecialPollInterval
In the right pane, right-click SpecialPollInterval, then click Modify.

In the Edit DWORD Value box, under Value Data, type the number of seconds you want for each poll, ie 900 will poll every 15 minutes, then click OK.
To configure the time correction settings, locate:
HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesW32Timeconfig

In the right pane, right-click MaxPosPhaseCorrection, then Modify, in the Edit DWORD Value box, under Base, click Decimal, under Value Data, type a time in seconds such as 3600 (an hour) then click OK.
Now go back and click:

HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesW32Timeconfig
In the right pane, right-click MaxNegPhaseCorrection, then Modify.

In the Edit DWORD box under base, click Decimal, under value data type the time in seconds you want to poll such as 3600 (polls in one hour)
Exit Registry Editor

Now, to restart windows time service, click Start, Run (or alternatively use the command prompt facility) and type:

net stop w32time && net start w32time
And that’s it your time server should be now up and running.

Windows Time Server: Synchronising Your Network with NTP

Nearly all a computers activity involves time whether logging a timestamp for when a network was accessed to sending an email, knowing the time is crucial for computer applications.

All computers have an on-board clock that provides time and date information. These Real Time Clock (RTC) chips are battery backed so that even when off they can maintain time, however these RTC chips are mass produced and cannot maintain accurate time and tend to drift.

For many applications this can be quite adequate, however if a computer is on a network and needs to talk to other machines, failing to be synchonised to the correct time can mean many time-sensitive transactions can not be completed and can even leave the network open to security threats.

All versions of Windows Server since 2000 have included a time synchronization facility, called Windows Time Service (w32time.exe), built into the operating system. This can be configured to operate as a network time server synchronizing all machines to a specific time source.

Windows Time Service uses a version of NTP (Network Time Protocol), normally a simplified version, of the Internet protocol which is designed to synchronise machines on a network, NTP is also the standard for which most computer networks across the global use to synchronise with.

Choosing the correct time source is vitally important. Most networks are synchronized to UTC (Coordinated Universal Time) source. UTC is a global standardized time based on atomic clocks which are the most accurate time sources.

UTC can be obtained over the Internet from such places as time.nist.gov (us Naval Observatory) or time.windows.com (Microsoft) but it must be noted that internet time sources can not be authenticated which can leave a system open to abuse and Microsoft and others advise using an external hardware source as a reference clock such as a specialized NTP server.

NTP servers receive their time source from either a specialist radio transmission from national physics laboratories which broadcast UTC time taken from an atomic clock source or by the GPS network which also relays UTC as a consequence of needing it to pin point locations.
NTP can maintain time over the public Internet to within 1/100th of a second (10 milliseconds) and can perform even better over LANs.
To configure Windows Time Service to use an external time source simply follow these instructions.

Locate the registry subkey.
HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesW32TimeParameters
Right click type then Modify the Value by inserting NTP in the Value Data box.

Right click ReliableTimeSource, then Modify the Edit DWORD Value box, by inserting 0 (zero).

Right-click NtpServer then Modify the Edit Value by typing the Domain Name System (DNS), (note each DNS must be unique).

Now locate the original subkey and right-click Period Modify the Edit DWORD Value box with the poll interval (how often a NTP server polls the time), under Value Data (recommended 24)

Run the following command line, Net stop w32time && net start w32time.

Now enable NTP by locating the subkey, HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesW32TimeTimeProvidersNtpServer

Right click Enabled and modify the Value data box by typing 1.

Right Click SpecialPollInterval in the right pain of the subkey HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesW32TimeTimeProvidersNtpClientSpecialPollInterval.

Edit the DWORD value box the time you want for each poll (900 will poll every 15 minutes)

Locate HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesW32Timeconfig

To configure the time correction settings right click MaxPosPhaseCorrection, then modify the DWORD Value box with a time in seconds such (select decimal under base first, 3600 = one hour)

Now do the same for MaxNegPhaseCorrection the restart windows time service by running (or alternatively use the command prompt facility) net stop w32time && net start w32time.

To synchronise each machine simply type W32tm/ -s in the command prompt and the time server should now be working correctly (note it may take several polls before the correct time is displayed).
