Khronos KTX 2.0 Textures Enable Compact, Visually Rich, glTF 3D Assets

KTX LogoThe ratification of KTX™ 2.0, adds support for Basis Universal supercompression for reliable, ubiquitous distribution of GPU textures. Basis Universal is a compression technology developed by Binomial that produces compact textures that can be efficiently transcoded to a variety of GPU compressed texture formats at run-time. Additionally, Khronos® has released the KHR_texture_basisu extension enabling glTF™ to contain KTX 2.0 textures, resulting in universally distributable glTF assets that reduce download size and use natively supported texture formats to reduce GPU memory size and boost rendering speed on diverse devices and platforms. Lastly, Khronos has released open source tools and transcoders, together with developer and artist guidelines, to enable and encourage widespread usage of KTX 2.0 textures throughout the glTF ecosystem, including the three.js, Babylon.js and Gestaltor viewers that have already integrated support.

New Vulkan Website

Vulkan is enjoying a boom in adoption by world class developers and in order to showcase this exciting content, Khronos has created a new homepage for Vulkan. One of the first things you’ll notice is the prominent use of imagery across the site that will be updated periodically with new content. There is also a dedicated “Made with Vulkan” showcase, which is a living list of Vulkan content and reveals just how powerful and versatile the API is. If you have a Vulkan project that you would like to let us know about, please use the linked form on the "Made with Vulkan" page above the showcase. Please explore the new site and let us know what you think!
