Let's Build a Cross-Platform 3D Engine with Kotlin/Multiplatform
summary
A runnable prototype shares core matrix math, skeleton animation and asset formats across browser, JVM, Android and iOS using Kotlin/Multiplatform. Rendering uses OpenGL/WebGL/OpenGL ES, shared content uses kotlinx.serialization, and the talk explains the concrete process for converting a pure Kotlin/JVM library into Kotlin/Multiplatform and the platform adapters needed. It also reports limits: inability to build a single common API across different engines and practical issues like Kotlin/JS name conflicts and other nuisance bugs.
