Defines the WgpuAppAction trait and a winit event-loop driver (WgpuAppHandler) that normalizes async init, resize handling (including the wasm startup sizing quirk where no resize event fires), input events, and render dispatch across every example. A clean, self-contained app harness that can seed a new wgpu project for both native and wasm targets with minimal modification.

Encapsulates a GPU buffer pre-filled with per-frame animation data and a dynamic-uniform-offset bind group, a memory-efficient pattern for passing per-object or per-frame data without recreating or rebinding buffers. Extraction requires only the wgpu crate and is directly applicable to particle systems, skeletal animation, or per-instance time-varying uniforms.

A render-node abstraction that draws a fullscreen triangle strip without any vertex buffer by generating positions in the vertex shader. Reusable as-is for tone mapping, HDR presentation blits, Gaussian blur, and any post-processing pass; the pattern is decoupled from scene logic and demonstrates a non-obvious wgpu optimization.

Implements a complete HDR pipeline: offscreen 16F color target, ACES-style tone mapping in WGSL, and a final presentation pass, plus equirectangular-to-cubemap environment conversion for skyboxes and image-based reflections. A strong reference implementation that can be lifted into any wgpu renderer needing HDR output.

Generates heightfield terrain entirely on the GPU with a compute shader using FBM simplex noise, writing vertex/index data directly to storage buffers within a chunk-based abstraction. A reusable template for GPU-driven procedural mesh generation that avoids CPU round-trips and demonstrates storage-buffer vertex feeding.

Renders frames to an offscreen surface and reads the completed framebuffer back to CPU memory using the map/poll/copy sequence, then encodes the frames as a GIF. Demonstrates the GPU-to-CPU readback pattern required for screenshots, video capture, or extracting analytical data from a wgpu context.
