### AI overview

This article explains how tetrahedral cages reduce BVH memory usage and update costs when ray tracing independently animated geometry. In an AMD sample with animated plants, the technique uses about 1.7 GB of BVH memory and approximately 3.3 ms for BVH updates per frame, compared with up to 80 GB and more than 300 ms for conventional dense triangle BLAS updates on a Radeon RX 9070 XT GPU.

### Source excerpt

The AMD tetrahedral cage technique ray traces 25,000 independently animated plants at 60+ FPS while slashing BVH memory and update costs for massive dynamic scenes.

### AI overview

The article explains a ray-tracing method for massive animated scenes that uses low-resolution tetrahedral cages to deform geometry while reusing static mini-meshes and mini-BLASes. This reduces per-frame update and memory costs, with the paper demonstrating roughly 585 million animated triangles at 60 frames per second on an AMD Radeon RX 9070 XT at 1080p.

### Source excerpt

Animate compact tetrahedral cages and reuse static mini-BLASes to ray-trace hundreds of millions of triangles in real time, dramatically cutting per-frame update and memory costs for dense foliage, grass, and crowds.

### AI overview

ReactOS Newsletter 40 reports that the Microsoft DirectX runtime loads on ReactOS after required files are copied manually. The installer and 3D support still do not work, but simple hardware-accelerated 2D works in VMware Workstation. The newsletter also describes timing, locking, and memory-manager fixes, including a reported 150% installation performance improvement in Alex Ionescu's tests.

### Source excerpt

Microsoft DirectX Runtime First, let me state that legally, according to the whole Windows Genuine Advantage and EULA, you're not supposed to install the MS DirectX runtime on nongenuine Windows systems. On the other hand, the runtimes that come with various games as a prerequisite to playing the game aren't technically bound by the WGA. That aside, the MS DirectX runtime now loads on ReactOS. To get DX on, you need to manually copy the following files: dxg.
