04 · wgpu Image Texture

A native Tauri 2 + wgpu example showing the complete path from encoded image bytes to a sampled GPU texture.

Run

npm install
npm run dev

What it teaches

• Decode a bundled PNG in Rust with the image crate.
• Upload RGBA8 pixels with Queue::write_texture.
• Use an sRGB texture format so sampling produces linear color values.
• Bind a texture, sampler, and uniform buffer to WGSL.
• Compare nearest and linear filtering.
• Implement contain, cover, and stretch without CSS or a browser canvas.

The renderer window is a native wgpu surface. The WebView is used only for controls.

Backend and version policy

This project pins Tauri 2.11.5 and wgpu 29.0.4. It requests wgpu::Backends::PRIMARY, so native rendering uses Metal, Vulkan, or DX12 rather than a GL/GLES fallback.
