James is also currently looking at making a Skia backend for the Canvas (to replace Shiva), and Skia already has quite intensive SSE/NEON optimisations, in addition to an optimised OpenGL render which he expects to be substantially more performant than the current OSG Node/Drawable hierarchy.<ref>{{cite web | James is also currently looking at making a Skia backend for the Canvas (to replace Shiva, making a solution using Skia ([https://skia.org https://skia.org]) as the backend, because this would give good performance via its OpenGL backend, make people who don’t want to use Qt happier, and could also replace the OSG rendering of the Canvas within FlightGear itself, allowing us to ditch ShivaVG (which is unmaintained) and probably improve performance substantially. (Skia can do SSE3/NEON optimised software rendering in a background thread, so Canvas wouldn’t eat into our OSG / triangle budget)<ref>{{cite web | ||
