Watki is an offline field guide to open graphics, compute and XR standards. Every call, built-in and type, with what it does, what it takes and where it fits, set in a quiet black-and-white reader that works without a connection. WHAT'S INSIDE 21 volumes and more than 12,000 entries, including: • Vulkan 1.4 and Vulkan SC 1.0, with extensions • OpenGL ES 2.0 to 3.2, OpenGL 4.6 core and OpenGL SC 2.0 • EGL 1.5 and WebGL 1.0 and 2.0, with extensions • OpenCL 3.0 and OpenCL C, SYCL 2020 and SPIR-V 1.6 • OpenXR 1.1, OpenVX 1.3.1, OpenVG 1.1 and ANARI 1.1 • The Slang core module • glTF 2.0, KTX 2.0, COLLADA 1.5 and NNEF 1.0.5 • Short overviews of machine learning and safety-critical work HOW IT READS • Each volume opens to its sections; each section lists its entries in groups you can jump between. • Entries show the signature, parameters, return values and the version or extension that added them. • Search across every volume at once. • Keep the entries you use most and come back to recent ones. • See how much of each volume you have read. MADE TO BE LOOKED AT A slow mist drifts behind the pages and changes with the time of day. You can thicken it, slow it, freeze it or give it a new pattern. In the darkroom you can develop any photo as a 1-bit print and save it. PRIVATE AND OFFLINE Everything ships inside the app. No account, no ads, no tracking and no data collected.
