Tessellation quality options

Fields

feathering: bool

Use “feathering” to smooth out the edges of shapes as a form of anti-aliasing.

Feathering works by making each edge into a thin gradient into transparency. The size of this edge is controlled by Self::feathering_size_in_pixels.

This makes shapes appear smoother, but requires more triangles and is therefore slower.

This setting does not affect text.

Default: true.

feathering_size_in_pixels: f32

The size of the the feathering, in physical pixels.

The default, and suggested, value for this is 1.0. If you use a larger value, edges will appear blurry.

coarse_tessellation_culling: bool

If true (default) cull certain primitives before tessellating them. This likely makes

prerasterized_discs: bool

If true, small filled circled will be optimized by using pre-rasterized circled from the font atlas.

round_text_to_pixels: bool

If true (default) align text to mesh grid. This makes the text sharper on most platforms.

debug_paint_clip_rects: bool

Output the clip rectangles to be painted.

debug_paint_text_rects: bool

Output the text-containing rectangles.

debug_ignore_clip_rects: bool

If true, no clipping will be done.

bezier_tolerance: f32

The maximum distance between the original curve and the flattened curve.

epsilon: f32

The default value will be 1.0e-5, it will be used during float compare.
