shimmer

“The shimmer is a prism but it refracts everything.”- Annihilation (2018)

Image transformation in wasm using Go.

LIVE DEMO at https://agniva.me/shimmer/

Just a demo project done on a weekend to play with images inside the browser using WASM. Performance lag is noticeable for images over 100KB.

Setup

• Run make build-prod
• Serve the files using any HTTP server. (Note that .wasm files need to be served with application/wasm mime type. So the server must be capable of doing that.)
