Implementations

impl Renderer

pub fn new(device: Device, queue: Queue) -> Self

pub fn read_texture_rgbau8( &self, texture: &Texture, size: (u32, u32), ) -> Vec<u8>

Reads RGBA pixel data from a GPU texture into a CPU-accessible byte vector.

Arguments

• texture - The texture to read from
• size - The (width, height) dimensions of the texture

Returns

A Vec containing RGBA pixel data in row-major order

pub fn render<C: Camera>( &mut self, texture: &Texture, texture_format: TextureFormat, instances: &mut [RenderInstance], camera: &C, clear_color: &Color<f64>, )

Renders a collection of instances to a texture using the specified camera and clear color. Updates shared camera matrices, processes each render instance, and submits commands to the GPU.

Arguments

• texture - The target texture to render to
• texture_format - The format of the target texture，used to build a render pipeline
• instances - Mutable slice of render instances to draw
• camera - Camera providing view and projection matrices
• clear_color - Background color to clear the texture with
