I was kinda hoping the triangle PR would make the cut…

We had to get this release out, as it was meant to be a smaller release, but between moving to GitHub, writing a wiki from scratch, helping Fedora migrate to sdl12-compat, etc, we were months behind schedule.

The triangle rendering pull request is flagged for the 2.0.18 milestone, and if we don’t have a major disaster, we really do want to ship on a shorter timeline this time. Famous last words though, I know.

I just had a geek orgasm over SDL_RenderGeometry. This is huge! It’s even more exciting than when float rendering functions were added. I’m not even being sarcastic here, lol. This feature adds so many possibilities. Thank you so much to the devs who finally put this together :heart_eyes:

@icculus Is it feasible to add a version of SDL_RenderGeometry that takes 4 points to make a 4 vertex shape? :pray:

I played around a bit with the upcoming SDL_RenderGeometry() function.
Even though I use OpenGL nowadays for such rendering, it’s very nice to see such functionality coming to SDL itself!
