- x86 - 32bit (SSE, SSE2, ...), 64bit
|
|
- Arm - thumb, arm, NEON, ... 64bit?
|

Optimize for GPU variety
|
|
- Nvidia

|
- Qualcom
|
|
- Imagination
|
|
- ...
|
|
- ES2 -vs- ES3 -vs- Desktop profiles
|
|
|
|
Lots of testing and measuring
|
|
- build-bots
|
|
-- unittests, micro-benchmarks, image-regressions
|
|
-- http://108.170.217.252:10117/console
|
|
- webpage archives (in progress)
|
|
-- "map-reduce" server for saerching/historgrams
|
|
-- macro-benchmarks, image-reressions
|
|
-- gpu : cpu fuzzy compares

|
|
|
Roadmap in a nutshell
|
|
- GPU performance
|
|
- Pictures
|
|
- Images
|
|
- Fonts
|
|
- PDF
|
|
|
|
Roadmap : GPU Performance
|
|
- Clipping changes are expensive
|
|
- Texture cache optimizations
|
|
- Better batching / reordering
|
|
- Rely more on multi-sampling
|
|
- ES3/desktop features (e.g. path-rendering)
|
|
- ... continuo ad absurdum
|
|
|
|
Roadmap : Pictures
|
|
- Playback performance
|
|
-- improve culling
|
|
-- multi-core support
|
|
- Record performance
|
|
-- improve hash/cache
|
|
-- improve measuring/bbox computation
|
|
- Feedback to clients
|
|
-- annotations
|
|
-- heat-map for time spent drawing
|
|
-- peep-hole optimizations
|
|
|
|
Roadmap : Images
|
|
- HQ filtering and mipmaps
|
|
- Unpremul support
|
|
- sRGB support (future)
|
|
- Improve cache / lazy-decoding
|
|
|
|
Roadmap : Fonts
|
|
- Color emoji
|
|
- DirectWrite on windows
|
|
-- subpixel positioning!
|
|
- new FontMgr -- extended styles
|
|
|
|
Roadmap : PDF
|
|
- Android
|
|
-- perspective, color-filters
|
|
- New Viewer project
|
|
-- print-preview and more
|
|
-- can output picture / gpu directly
