Struct DrawBatch 

pub struct DrawBatch {
    pub circles: Vec<[f32; 7]>,
    pub rects: Vec<[f32; 8]>,
    pub lines: Vec<[f32; 9]>,
}

Draw call batching for GPU efficiency.

Fields

circles: Vec<[f32; 7]>

Batched circles (center_x, center_y, radius, color_rgba)

rects: Vec<[f32; 8]>

Batched rectangles (x, y, w, h, color_rgba)

lines: Vec<[f32; 9]>

Batched lines (x1, y1, x2, y2, width, color_rgba)

Implementations

impl DrawBatch

pub fn new() -> Self

Create a new batch.

pub fn add_circle( &mut self, x: f32, y: f32, radius: f32, r: f32, g: f32, b: f32, a: f32, )

Add a circle to the batch.

pub fn add_rect( &mut self, x: f32, y: f32, w: f32, h: f32, r: f32, g: f32, b: f32, a: f32, )

Add a rectangle to the batch.

pub fn add_line( &mut self, x1: f32, y1: f32, x2: f32, y2: f32, width: f32, r: f32, g: f32, b: f32, a: f32, )

Add a line to the batch.

pub fn clear(&mut self)

Clear all batches.

pub fn unbatched_draw_calls(&self) -> usize

Total draw calls if not batched.

pub fn batched_draw_calls(&self) -> usize

Actual draw calls with batching (3 max: circles, rects, lines).
