Struct MultiBackendRenderer 

pub struct MultiBackendRenderer {
    pub backend: Box<dyn BackendContext>,
    pub capabilities: BackendCapabilities,
    /* private fields */
}

The main renderer that dispatches draw calls and compute through a BackendContext.

Fields

backend: Box<dyn BackendContext>

capabilities: BackendCapabilities

Implementations

impl MultiBackendRenderer

pub fn new( backend: Box<dyn BackendContext>, capabilities: BackendCapabilities, ) -> Self

pub fn software() -> Self

Create a renderer backed by the software context.

pub fn from_existing_pipeline(_pipeline: &()) -> Self

Build a renderer from an existing pipeline’s backend selection. In practice this would inspect the live Pipeline; here we default to Software.

pub fn begin_frame(&mut self)

Begin recording a new frame.

pub fn end_frame(&mut self)

Finish recording and submit all commands.

pub fn present(&mut self)

Present the current frame to the display.

pub fn frame_count(&self) -> u64

Number of frames completed so far.

pub fn draw(&mut self, _pass: &RenderPass, calls: &[DrawCall])

Execute a series of draw calls within a render pass.

pub fn dispatch_compute( &mut self, pipeline: ComputePipelineHandle, workgroups: [u32; 3], buffers: &[BufferHandle], )

Dispatch a compute shader.

pub fn read_buffer(&self, buffer: BufferHandle) -> Vec<u8>

Read data back from a GPU buffer.

pub fn upload_buffer(&mut self, buffer: BufferHandle, data: &[u8])

Upload raw bytes to a GPU buffer.

pub fn upload_texture(&mut self, texture: TextureHandle, data: &[u8])

Upload raw pixel data to a texture.

pub fn create_vertex_buffer(&mut self, data: &[u8]) -> BufferHandle

Create a vertex buffer and fill it with the given data.

pub fn create_index_buffer(&mut self, data: &[u8]) -> BufferHandle

Create an index buffer and fill it.

pub fn create_uniform_buffer(&mut self, data: &[u8]) -> BufferHandle

Create a uniform buffer and fill it.

pub fn create_storage_buffer(&mut self, size: usize) -> BufferHandle

Create a storage buffer.

pub fn create_color_texture(&mut self, w: u32, h: u32) -> TextureHandle

Create a colour texture.

pub fn create_depth_texture(&mut self, w: u32, h: u32) -> TextureHandle

Create a depth texture.

pub fn destroy_buffer(&mut self, buf: BufferHandle)

Destroy a buffer.

pub fn destroy_texture(&mut self, tex: TextureHandle)

Destroy a texture.

pub fn backend_name(&self) -> &str

Backend name.
