Wavefront The Advanced Visualizer 4.2.1 for SGI IRIX
The Advanced Visualizer (TAV) 是一个3D图形软件包,是Wavefront Technologies从1980年代到1990年代的旗舰产品。
与许多现代(2011)计算机图形动画软件相比,TAV是一组独立的程序,每个程序都专注于图像合成的一个方面,而不是单一的产品。这些较小程序的集合形成了整个套件,基于大多数ASCII文件格式(如OBJ)的简单交换。
TAV软件套件的主要组件包括:模型,绘画,动态,动画,预览和检查。也可作为图像合成的附加组件使用。许多原始实用程序(如图形转换)都包含在工具包中,并且经常用于通过 shell 脚本进行批处理。
模块化特性允许这些松散耦合的轻量级程序以相对较小的内存占用快速启动。运行模型或预览包的多个实例的情况并不少见,每个实例处理同一项目的不同方面。
由于TAV仅在Silicon Graphics平台上运行,因此由于它使用了SGI支持OpenGL前身IrisGL的专用图形硬件,因此与仅基于软件的解决方案相比,它具有显着的性能优势。
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.
