Struct vello::Renderer

pub struct Renderer { /* private fields */ }

Renders a scene into a texture or surface.

Implementations

impl Renderer

pub fn new(device: &Device, options: RendererOptions) -> Result<Self>

Creates a new renderer for the specified device.

pub fn render_to_texture( &mut self, device: &Device, queue: &Queue, scene: &Scene, texture: &TextureView, params: &RenderParams ) -> Result<()>

Renders a scene to the target texture.

The texture is assumed to be of the specified dimensions and have been created with the wgpu::TextureFormat::Rgba8Unorm format and the wgpu::TextureUsages::STORAGE_BINDING flag set.

pub fn render_to_surface( &mut self, device: &Device, queue: &Queue, scene: &Scene, surface: &SurfaceTexture, params: &RenderParams ) -> Result<()>

Renders a scene to the target surface.

This renders to an intermediate texture and then runs a render pass to blit to the specified surface texture.

The surface is assumed to be of the specified dimensions and have been configured with the same format passed in the constructing RendererOptions’ surface_format. Panics if surface_format was None

pub async fn render_to_texture_async( &mut self, device: &Device, queue: &Queue, scene: &Scene, texture: &TextureView, params: &RenderParams ) -> Result<Option<BumpAllocators>>

Renders a scene to the target texture.

The texture is assumed to be of the specified dimensions and have been created with the wgpu::TextureFormat::Rgba8Unorm format and the wgpu::TextureUsages::STORAGE_BINDING flag set.

The return value is the value of the BumpAllocators in this rendering, which is currently used for debug output.

This return type is not stable, and will likely be changed when a more principled way to access relevant statistics is implemented

pub async fn render_to_surface_async( &mut self, device: &Device, queue: &Queue, scene: &Scene, surface: &SurfaceTexture, params: &RenderParams ) -> Result<Option<BumpAllocators>>
