Alias/Wavefront RLE Image Format (.pix)
The PIX file extension stands for Alias/Wavefront Run-Length Encoding (RLE) Image Format. Developed by Alias Systems Corporation (later acquired by Autodesk), it was designed for storing bitmap images in PowerAnimator and Alias 3D software. This format was instrumental in creating high-resolution 3D models and animations for movies and video games in the 1990s. The RLE compression minimized file size without compromising image quality, optimizing performance for graphics-heavy tasks. Although its usage has declined in favor of more versatile formats, PIX played a significant role in the evolution of computer graphics technology.
