# Prism

A node-based image compositing tool. Images flow through a directed acyclic
graph (DAG) of processing nodes (read, blend, colour-grade, etc.) and are
rendered via GPU shaders.

## Status

Early development. Scaffolding and exploratory scratchpad work.

## Language & Tooling

- **Language**: C11 / C++11 (dual-mode), following conventions in `src/wapp/`
- **GPU API**: Vulkan, abstracted behind a Rendering Hardware Interface (RHI)
- **Shading language**: Slang (`src/shaders/`)
- **Build**: TBD

## Dependencies

- `src/wapp/` — local utility library (vendored, provides allocators, arrays,
  strings, platform abstractions, etc.)
