Wavefront The Advanced Visualizer 4.2.1 for SGI IRIX

The Advanced Visualizer (TAV) 是一個3D圖形軟件包，是Wavefront Technologies從1980年代到1990年代的旗艦產品。

與許多現代（2011）計算機圖形動畫軟件相比，TAV是一組獨立的程序，每個程序都專注于圖像合成的一個方面，而不是單一的產品。這些較小程序的集合形成了整個套件，基于大多數ASCII文件格式（如OBJ）的簡單交換。

TAV軟件套件的主要組件包括：模型，繪畫，動態，動畫，預覽和檢查。也可作為圖像合成的附加組件使用。許多原始實用程序（如圖形轉換）都包含在工具包中，并且經常用于通過 shell 腳本進行批處理。

模塊化特性允許這些松散耦合的輕量級程序以相對較小的內存占用快速啟動。運行模型或預覽包的多個實例的情況并不少見，每個實例處理同一項目的不同方面。

由于TAV僅在Silicon Graphics平臺上運行，因此由于它使用了SGI支持OpenGL前身IrisGL的專用圖形硬件，因此與僅基于軟件的解決方案相比，它具有顯著的性能優勢。

The Advanced Visualizer (TAV), a 3D graphics software package, was the flagship product of Wavefront Technologies from the 1980s until the 1990s.

In contrast to many modern day (2011) computer graphics animation software, TAV was a set of independent programs that each focused on one aspect of image synthesis as opposed to a monolithic product. The collection of these smaller programs formed the entire suite based on simple interchange of mostly ASCII file formats such as OBJ.

The major components of the TAV software suite included: Model, Paint, Dynamation, Kinemation, Preview, and fcheck. Composer was also available as an add-on for compositing of imagery. Many primitive utility programs such as graphics conversion were included in the toolkit and were frequently employed for batch processing via shell scripts.

The modular nature allowed these loosely coupled lightweight programs to start-up quickly with relatively small memory footprints. It was not uncommon to run several instances of the Model or Preview package, each working on different aspects of the same project.

As TAV only ran on the Silicon Graphics platform it enjoyed significant performance advantages over software-only based solutions due to its use of SGI's specialized graphics hardware supporting IrisGL, a precursor to OpenGL.
