# cvkg-render-gpu
**cvkg-render-gpu** (Project Surtr) is the primary high-performance GPU renderer for CVKG, built on `wgpu`.
## Features
### `SurtrRenderer`
The "Forge" that translates CVKG drawing commands into GPU draw calls.
* **Muspelheim Pipeline**: A multi-pass rendering pipeline supporting advanced effects.
* **Bifrost (Frosted Glass)**: Real-time backdrop blur for refractive UI elements.
* **Gungnir (Neon Glow)**: Additive bloom pass for emissive borders and text.
* **Mjolnir (SDF Clipping)**: Sharp, geometric clipping for Cyberpunk aesthetics.
* **Vector Iconography (Lyon)**: Direct GPU tessellation of SVG paths for resolution-independent icons.
* **Multi-Window Architecture**: Shared `wgpu::Device` and `Queue` across multiple window surfaces for resource efficiency.
* **Batching**: Efficiently batches primitives into high-throughput vertex buffers.
* **Telemetry**: Built-in tracking for frame times, draw calls, and vertex throughput.
### Typography (Runic-Text)
* Integrates `cvkg-runic-text` for high-fidelity text layout.
* Maintains a dynamic GPU texture atlas for glyph caching.
* Supports subpixel positioning and custom font embedding.
### Integration
* Implements the `Renderer` trait from `cvkg-core`.
* Supports `accesskit_winit` for integrated accessibility.
* Handles native window surface management and configuration.
