Optimization: UI transform calculation #50

Open skejeton opened 4 months ago

skejeton commented 4 months ago

The main problem is that during font rendering each glyph is rendered as a separate bitmap, and each time a glyph is rendered, push_transform is called, which takes a lot of time to compute with so many calls.

What I understand to be possible solutions:

  1. glyph batching - combined bitmap / texture atlas
  2. transform caching - use hash table to store transform results
  3. gpu acceleration?

What do you think are tradeoffs of various approaches and which ones you prefer and why?

I'll get back to it when optimizing, I think caching will be the easiest.
