Struct GeometryBatch 

pub struct GeometryBatch { /* private fields */ }

CPU-side geometry batch flushed each frame through the UI render pipeline.

Implementations

impl GeometryBatch

pub fn new( device: &Device, pixel_format: TextureFormat, size: (i32, i32), ) -> Self

Creates a geometry batch with pre-allocated vertex capacity and a UI render pipeline.

pub fn resize_vertices(&mut self, size: (i32, i32))

Updates the viewport size stored in all pre-allocated vertices.

pub fn flush(&mut self, render_pass: &mut RenderPass<'_>, queue: &Queue)

Uploads accumulated vertices to the GPU and draws them.

Resets the vertex count after drawing. No-op if no vertices were added.

pub fn triangle(&mut self, positions: &[UIPosition; 3], color: UIColor)

Adds a filled triangle (3 vertices).

pub fn quad(&mut self, positions: &[UIPosition; 4], color: UIColor)

Adds a filled quad as two triangles (6 vertices).

pub fn line( &mut self, position: UIPosition, length: f32, angle: f32, thickness: f32, color: UIColor, )

Adds a line segment as a thin quad rotated by angle degrees.

pub fn arc( &mut self, origin: UIPosition, radius: f32, degree_begin: f32, degree_end: f32, thickness: f32, color: UIColor, )

Adds an arc outline approximated by line segments.

pub fn filled_arc( &mut self, origin: UIPosition, radius: f32, degree_begin: f32, degree_end: f32, color: UIColor, )

Adds a filled arc (pie slice) approximated by triangles.

pub fn rectangle( &mut self, position: UIPosition, size: UIPosition, thickness: UIBorderThickness, color: UIColor, radii: UICornerRadii, )

Adds a rounded rectangle border outline.

pub fn filled_rectangle( &mut self, position: UIPosition, size: UIPosition, color: UIColor, radii: UICornerRadii, )

Adds a filled rounded rectangle.
