An unholy fusion of Rust and C++ in physx-rs

Unsafe automatically-generated Rust bindings for the NVIDIA PhysX C++ API.

At SEED we developed a mini-game for autonomous agents: PICA PICA. It was the cutest Skynet implementation around.
It used a hybrid renderer: rasterization meets raytracing meets specialized denoising. I worked on global illumination, reflections, shadows, and a bunch more.
Runtime loading of object files, relocation of DLLs. Mostly harmful stuff.
Practical application of the GCN hacks: indirect dispatch of lots of unique compute shaders and native barycentric coordinate access. Those allows for efficient surface shading in a deferred manner without the use of ubershaders. Geometry and material descriptions can be decoupled, and we gain a lot of control over shading frequency. Slides here!
AMD’s Graphics Core Next GPU architecture has a number of interesting features which one cannot access via standard APIs. I show how to hack around the OpenGL driver, and feed it native shaders written in GCN ISA instead of GLSL. Slides here!
Importance sampled screen-space reflections with a novel spatiotemporal filter. I prototyped it in a toy engine written in the Rust language, and later ported to Frostbite, working closely with Yasin Uludag. It first shipped in Mirror’s Edge and Need for Speed.
