Official repository for the Vector Prism paper. This project implements the pipeline used in the paper to animate SVGs: SVG input → semantic parsing → LLM/VLM-driven planning → CSS/HTML generation.

Export per-frame PDFs/PNGs (headless Chrome required):

python utils/export_frames.py --input_file path/to/animation.html --fps 24 --duration 5 --format pdf
