Hi, I would like to promote performance & quality improvements on the rasterizer that I could do in jdk10 within a tiger team focused on fx rendering:
- multithreaded rendering (Marlin is thread-safe) ie the javafx could do parallel rendering of layers or shapes - software rasterizers: optimize inner / outer strokes, clipping in particular for dashes, intersection of curves with scanlines (integer maths) - rendering quality: use exact pixel coverage (agg approach), gamma corrected blending - in general: optimize array/buffer copies and memory allocations in the complete javafx stack (jvmstat + profiling) - use value types and more generally, enjoy vahalla, panama integration to improve java and c code in the rendering pipeline - gpu / shader upgrade ? Finally all these items represent an important workload that need both Oracle and OSS contributors = manpower. The main issue consists in building a team with new contributors. Maybe some Oracle or OpenJDK sponsorship is needed to fund such team ie donate some money for some contributions... at least to organise meetings. Let me cite the GNU philosophy: Thus, “free software” is a matter of liberty, not price. To understand the concept, you should think of “free” as in “free speech,” not as in “free beer”. Cheers, Laurent
