Simulating fluids, fire, and smoke in real-time
Summary: Andrew Chan discusses simulating fluids, fire, and smoke in real-time using GPUs. He explains the math behind fluid dynamics, parallel algorithms for modeling fluids, and the extra combustion bits that make fire special. The article covers fluid simulation, the Navier-Stokes equations, vorticity confinement, and fire simulation. The author demonstrates how to implement these simulations using WebGL and provides examples of their applications in movies and video games.

Vulkan video extensions for accelerated H.264 and H.265 encode
Summary: Khronos has finalized Vulkan Video extensions for accelerated H.264 and H.265 encoding. The release of Vulkan 1.3.274 enables a standardized, seamless, low-overhead, and highly controllable way to produce H.264 and H.265 video using hardware accelerators. The extensions offer improved rate control configuration, quality vs. performance trade-offs, and advanced hardware capabilities. An AV1 decode extension release is imminent, with an AV1 encode extension development underway.
