Struct epaint::tessellator::Tessellator

pub struct Tessellator { /* fields omitted */ }

Converts Shapes into triangles (Mesh).

For performance reasons it is smart to reuse the same Tessellator.

Se also tessellate_shapes, a convenient wrapper around Tessellator.

Implementations

impl Tessellator

pub fn from_options(options: TessellationOptions) -> Self

Create a new Tessellator.

pub fn tessellate_shape(
    &mut self,
    tex_size: [usize; 2],
    shape: Shape,
    out: &mut Mesh
)

Tessellate a single Shape into a Mesh.

• tex_size: size of the font texture (required to normalize glyph uv rectangles).
• shape: the shape to tessellate.
• out: triangles are appended to this.

pub fn tessellate_text(
    &mut self,
    tex_size: [usize; 2],
    text_shape: TextShape,
    out: &mut Mesh
)
