Arm announces astcenc 2.0 ASTC compression tool

Arm is delighted to announce astcenc 2.0! The ‘astcenc’ ASTC compression tool was first developed by Arm while ASTC was progressing through the Khronos standardization process seven years ago. astcenc has become widely used as the de facto reference encoder for ASTC, as it leverages all format features, including the full set of available block sizes and color profiles, to deliver high-quality encoded textures that are possible when effectively using ASTC’s flexible capabilities. This is a major update which provides multiple significant improvements for middleware and content creators. Learn move about astcenc 2.0 in the Khronos blog ‘Create ASTC textures faster with the new astcenc 2.0 open source compression tool’ written by our guest, Peter Harris, from Arm.

New ASTC Guide Released by Arm

Arm has released a new comprehensive ASTC Guide to help developers who wish to use ASTC technology to compress textures for 3D games and applications. The new guide contains a detailed ASTC algorithm overview, explains ASTC benefits, provides developers advice for achieving best compression results, and contains information on popular encoding tools—as well as usage with game engines.

In February 2020, Arm made its open source ASTC encoder available under the widely accepted Apache 2.0 license, enabling developers everywhere to easily generate ASTC textures during application development. Meanwhile, Khronos’ glTF™ 3D asset format standard, is adding ASTC support to enable glTF Universal Textures to be decoded into ASTC on the fly on the target system. With these recent developments we wanted to reach out to the developer community to explore how ASTC is being used, and whether there are remaining barriers to adoption that Khronos and Arm can help address. Consequently, Arm conducted a game developer survey to learn.

Google’s new Android Extension Pack and OpenGL ES 3.1 are supported in the upcoming Android L release. The Android Extension Pack is a set of extensions to OpenGL ES which provides features like tessellation to improve the detail of geometry rendered onscreen, and geometry shaders which can also be used to add detail to what is rendered onscreen as well as to add shadows to a scene. The Android Extension Pack also includes support for compute shaders, and Adaptive Scalable Texture Compression (ASTC).
