ORIPA

Per i progettisti e gli appassionati di origami - pareggio e modelli di prova piega in movimento!

Based on Jun Mitani's ORIPA desktop application, ORIPA for Android enables origami designers and enthusiasts to test their crease pattern ideas even while on the go! ORIPA for Android retains the ability to check crease patterns against local flat foldability rules and test fold valid crease patterns. Useful for when inspiration for a new origami design strikes while you're away from your computer, or during long flights to origami conventions with no Wi-Fi.

Features:

- Tools to draw, check, and fold crease patterns

- Compatible with desktop ORIPA - import and export crease patterns as OPX or CP files

- Save images of crease patterns and folded models as PNG or SVG

- Undo/redo drawing actions

- Multi-touch gestures such as pinch-to-zoom, two-fingered panning, two-fingered rotating of folded models

- Both landscape and portrait orientations are supported

Notes:

- ORIPA can only fold 2D models; checking and folding of 3D origami models is currently not supported

- ORIPA can only draw straight lines; curved lines are not supported

- ORIPA assumes existing knowledge of crease pattern analysis (e.g. Kawasaki's and Maekawa's theorems) and basic geometry (angle bisectors, etc.)

- ORIPA will not teach the user how to design or understand origami crease patterns
