0.31.0 - 2025-02-04 - Scene container, improved rendering quality

Highlights ✨

Scene container

This release adds the Scene container to egui. It is a pannable, zoomable canvas that can contain Widgets and child Uis. This will make it easier to e.g. implement a graph editor.

Clearer, pixel perfect rendering

The tessellator has been updated for improved rendering quality and better performance. It will produce fewer vertices and shapes will have less overdraw. We've also defined what CornerRadius (previously Rounding) means.

We've also added a tessellator test to the demo app, where you can play around with different values to see what's produced:

tessellator-test.mp4

Check the PR for more details.

CornerRadius, Margin, Shadow size reduction

In order to pave the path for more complex and customizable styling solutions, we've reduced the size of CornerRadius, Margin and Shadow values to i8 and u8.

Migration guide

• Add a StrokeKind to all your Painter::rect calls #5648
• StrokeKind::default was removed, since the 'normal' value depends on the context #5658
  • You probably want to use StrokeKind::Inside when drawing rectangles
  • You probably want to use StrokeKind::Middle when drawing open paths
• Rename Rounding to CornerRadius #5673
• CornerRadius, Margin and Shadow have been updated to use i8 and u8 #5563, #5567, #5568
  • Remove the .0 from your values
  • Cast dynamic values with as i8 / as u8 or as _ if you want Rust to infer the type
    • Rust will do a 'saturating' cast, so if your f32 value is bigger than 127 it will be clamped to 127
• RectShape parameters changed #5565
  • Prefer to use the builder methods to create it instead of initializing it directly
• Frame now takes the Stroke width into account for its sizing, so check all views of your app to make sure they still look right. Read the PR for more info.
