Intro
-----
Basis Universal™ v2.0 is an open source [supercompressed](http://gamma.cs.unc.edu/GST/gst.pdf) LDR/HDR GPU compressed texture interchange system from Binomial LLC that supports two intermediate file formats: the [.KTX2 open standard from the Khronos Group](https://registry.khronos.org/KTX/specs/2.0/ktxspec.v2.html), and our own ".basis" file format. These file formats support rapid transcoding to virtually any compressed [GPU texture format](https://en.wikipedia.org/wiki/Texture_compression) released over the past quarter century.

Our overall goal is to simplify the encoding and efficient distribution of *portable* LDR and HDR GPU texture, image, and short [texture video](https://github.com/BinomialLLC/basis_universal/wiki/Encoding-ETC1S-Texture-Video-Tips) content in a way that is compatible with any GPU or rendering/graphics API.
## GPU Textures are Infrastructure
Our overall goal is to simplify the encoding and efficient distribution of *portable* LDR and HDR GPU texture, image, and short [texture video](https://github.com/BinomialLLC/basis_universal/wiki/Encoding-ETC1S-Texture-Video-Tips) content in a way that is compatible with any GPU or rendering/graphics API.
The system supports seven modes (or codecs). In the order they were implemented:
1. **ETC1S**: A supercompressed subset of ETC1 designed for very fast transcoding to other LDR texture formats, low/medium quality but high compression, slightly faster transcoding to other LDR texture formats vs. libjpeg.
