3DEqualizer4 là một giải pháp 3D tracking hàng đầu hiên nay trong lĩnh vực VFX, được phát triển từ năm 2009 bởi Science-D-Visions của Đức. Ngay từ lúc ra mắt nó đã tạo ra một hiệu ứng rất tích cực đối với cộng đồng làm VFX trên toàn thế giới. Đến nay, 5 trong 10 hãng làm hậu kỳ hàng đầu thế giới đã lựa chọn 3DEqualizer4 cho hệ thống matchmove cảu mình, đó là: Double Negative, Prime Focus World, Cinesite, Weta Digital và MPC.

3DEqualizer4 is by no doubt the world’s leading 3D tracking solution, for merging live action footage with digital visual effects. Since its introduction in 2009, it has taken the vfx community by storm. Up to now, five of the ten world leading post-production houses decided to acquire a facility-wide site license, making 3DEqualizer4 their major matchmove system: Double Negative, Prime Focus World, Cinesite, Weta Digital and MPC.

But this is just the tip of the iceberg. In fact, 3DEqualizer4 is widely being used throughout the entire industry, which means if you go to the box office today to watch the latest visual effects driven blockbuster movie, you will most likely be entertained by the help of our work!

3DEqualizer is not just software!

The best product is nothing worth without reliable support – this is even more important for professional users. To make sure we provide the best possible, professional service, every support request is handled directly by those developer who is responsible for that specific part of 3DEqualizer. In addition, support requests are worked on with the highest priority, which means we usually respond within just a few hours. As a side effect, our developers immediately learn first hand about any existing problems and furthermore are constantly in touch with our users, discussing new feature requests and how to improve 3DEqualizer in general. On top of that, some of our developers go out from time to time and visit a client for a couple of weeks, in order to work on large-scale productions.

The things we learn, while using 3DEqualizer under real production conditions, makes us understand our client’s demands much better, which usually ends up in the development of entirely new features. Good examples of this cooperation – thanks to Weta Digital – has been our work on “Return of The King”, “King Kong”, “The Hobbit” and “Man of Steel”!

The most important cornerstone of our development philosophy is to do our own research. Almost every piece of technology that leaves our lab, represents a unique, proprietary solution which cannot be found in any other product. These proprietary pieces of technology are ranging from 3D calculation cores, over 2D tracking engines to realtime image decompression/manipulation routines – to name just a few. Doing our own research is time consuming and expensive, but it let’s us fully understand the technology we build, and thus we are able to provide our clients with highest quality tool sets!

 

 

• Unique Solver

 

3DE4’s calculation core applies a unique technique which automatically computes individual weighting curves for each point on a frame-by-frame basis. It allows to identify and get rid of so-called outliers on-the-fly (points of inconsistent or totally wrong 2D tracking). This new technology and a few other, up to now unseen, methods cause 3DE4’s calculation core to be very robust and extraordinary precise.

 

 

• High Speed Optimization

 

Parameter optimization is mandatory for a modern matchmoving application and 3DEqualizer4 provides countless options for doing just that. To increase productivity dramatically however, 3DE4 distributes optimization jobs over the network which results in up to 1000 times faster response times and thus essentially leads to better solves in the end.

 

• Deep Python Integration

 

Integrating 3DEqualizer4 into any existing production pipeline, is made easy through its Python scripting interface. More than 650 individual commands provide access to 3DE4’s internal data structures. In addition, complex and feature rich user interface extensions can be scripted which makes 3DE4 even more flexible.

 

• Lens Distortion

 

3DEqualizer4 is designed to handle every possible lens distortion scenario for spherical, anamorphic or fisheye lenses through its build in distortion models. On top of that, dynamically changing distortion caused by a zoom, focus pull or both at the same time poses no threat either, because of 3DE4’s powerful 1D- and 2D-lookup table tools, as well as parameter curve optimization.

 

• Academy Award® Winner

 

3DEqualizer is the matchmove software of choice for the world’s leading vfx facilities. Out of 17 productions, honored with an Academy Award for Best Visual Effects since 1998, 11 utilized 3DEqualizer as their major 3D tracking solution: Gladiator, The Lord Of The Rings, Avatar, Inception, Gravity, Interstellar – to name just a few.

 

• 20 Years Experience

 

Founded in December 1995, Science-D-Visions is among the pioneers of modern matchmoving. Our 20 years of experience in this field led us to the development of 3DEqualizer4, which in our eyes represents by far the world’s most powerful 3D tracking software!

New in R4

• added new “ScriptDB Installer” (download & installation of 3DE.com “ScriptDB” custom scripts)
• removed some old, obsolete scripts
• removed some custom scripts from standard installation (now found in 3DE.com “ScriptDB”)
• re-release of PLE version
• bugfixes and (stability) improvements for flcd4 (v2.0b3)
• when in “LICENCE_MANAGER_3DE4_USER_ONLY_MODE” configured “3DE ID” isn’t shown anymore
• fixed a bug which caused 3DE to add unwanted whitespaces to a user’s “3DE ID”
• introduced an all new “rolling shutter to nuke export” script now based on “gridwarp” instead of “cornerpin”
• added new command “flushConsoleOutput()” which forces 3DE to update its console while a script is still running
• added new “TIMER” & “ADJUSTMENT” hints (for python command “getCurrentScriptCallHint()”)
• fixed a bug which could cause 3DE to crash when adjusting large numbers of parameters (>50)
• fixed a bug which could cause 3DE to crash when calling command “addOptionMenuWidget()” with large “item” strings
• added some eye candy to script “filter curves” (v1.6)
• added some more eye candy to script “save out rendered frames” (v1.6)
• added new “-focal_length” command line option to warp4 (v1.4)
• fixed a number of calculation core related bugs
