Add improved text rendering #1363

Open ghutchis opened 1 year ago

ghutchis commented 1 year ago

Right now, the text labels aren't great, particularly compared to high-resolution anti-aliased text on retina screens.

We need a better solution, for example multi-channel signed distance fields: https://github.com/Chlumsky/msdfgen

We can also use open source fonts (e.g., STIX fonts: https://github.com/stipub/stixfonts)

@ghutchis do you still need help?

ghutchis commented 11 months ago

Yes, definitely. Here's how text labels look in the current renderer on my Mac Retina screen. Some of this work may require updating to the OpenGL core profile (e.g., using pixel shaders)
