Graphics Programming with Kotlin
summary
Kotlin code shows concrete recipes: Android KTX provides extension properties to pack/unpack 32-bit color ints, plus destructuring operators and operator overloads for rectangle union/intersection and pixel get/set so bitmap[x,y] and sub-rect ranges read cleanly. A GLSL ray tracer ports to Kotlin math with minimal changes and runs on CPU using coroutines and a 3x CPU dispatcher to move from ~50% to ~99.9% core utilization. Kotlin 1.3 adds inline classes and unsigned types that give zero-cost abstractions with caveats about boxing.
