Adaptive Scalable Texture Compression (ASTC) using the SeeMore demo
This demo takes the SeeMore demo previously developed to show OpenGL® ES 3.0 and Geomerics’ global illumination engine, Enlighten™, and uses ASTC as the primary compression format.
The benefit of ASTC is that it has many texture compression options that allow the artist to specify the desired quality and memory footprint characteristics very precisely. In this video we show comparisons of memory usage and image quality between raw, ETC2, ASTC 5×5 and ASTC 6×6.
The overall result when textures are compressed with ASTC is an improved image quality, lower bandwidth usage and significantly reduced energy consumption.
