I&#x27;ve been doing 3D and film&#x2F;video at the time on SGIs. While true that CPUs gained in performance on other platforms, IRIX machines were 64-bit, had great 3D accelerators (OpenGL was SGI&#x27;s in fact) and - most importantly - they had bus bandwidth which was very important for large amount of data image processing required. Also, proprietary I&#x2F;O was available for video and film which was only starting to come out for PCs (FAST and TARGA cards were getting cheap). It&#x27;s all funny considering there was a void in the market. SGI (and discreet for video and A|W and Softimage for 3D) was great, if you could afford it, for high end broadcast and film and PC was nearly usable for video, but not for film still. Mac was great for video editing, but not for 3D... etc. Amiga was great for everything for video (not film), but it was, at that point, dead for several years.
