# 3D Spherical Projection Animation — Jetpack Compose

**[droidcon](https://daily.dev/sources/droidcon)** · 7 min read · 0 upvotes · 0 comments

## Summary

Learn to build a 3D spherical projection animation in Jetpack Compose using mathematical concepts like spherical-to-Cartesian coordinate conversion, perspective projection, and rotation matrices. The tutorial covers transforming 3D coordinates to 2D screen space without camera APIs, implementing user interaction for sphere rotation, and using the Fibonacci sphere algorithm for even element distribution. Includes complete code examples with trigonometry, graphics layer transformations, and techniques for creating depth and scale effects.
