+
+[Rusty Vangers] ([GitHub][vangers-src], [Itch-io][vangers-itch]) is an
+experimental re-implementation of the [Vangers] game,
+using GPUs and multi-threading in Rust.
+
+The project has started with a strong focus on rendering,
+since efficient GPU implementation of a Voxel world as large as
+2048x16384x256 (that's about 8 giga-voxels!) turned into a tough challenge,
+even though the original game from 1998 easily does it on CPU.
+
+Finally, after years of experiments, a method has been implemented
+that is fast and universal when it comes to viewing angles. It's based
+on an acceleration structure in the form of a voxel octree.
+This work has landed at the start of November, and now it's possible
+to [ride through][vangers-video] the strange worlds
+while looking from behind the car, or even from inside it.
+
+This method runs on all APIs (including OpenGL!), thanks to wgpu/naga
+portability. It's suitably fast, regardless of perspective, even on
+an old macBook with an integrated GPU. It concludes the rendering story
+of the project, and the devs can shift focus on other areas.
