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.)
