Struct nannou::draw::renderer::Renderer

pub struct Renderer { /* private fields */ }

A helper type aimed at simplifying the rendering of nannou primitives via wgpu.

Implementations

impl Renderer

pub const DEFAULT_DEPTH_FORMAT: TextureFormat = wgpu::TextureFormat::Depth32Float

The default depth format

pub const DEFAULT_GLYPH_CACHE_SIZE: [u32; 2] = _

The default size for the inner glyph cache.

pub const DEFAULT_GLYPH_CACHE_SCALE_TOLERANCE: f32 = 0.100000001f32

The default scale tolerance for the glyph cache.

pub const DEFAULT_GLYPH_CACHE_POSITION_TOLERANCE: f32 = 0.100000001f32

The default position tolerance for the glyph cache.

pub const GLYPH_CACHE_TEXTURE_FORMAT: TextureFormat = wgpu::TextureFormat::R8Unorm

The texture format of the inner glyph cache.

pub const INDEX_FORMAT: IndexFormat = wgpu::IndexFormat::Uint32

The index format used to index into vertices.

pub fn new( device: &Device, output_attachment_size: [u32; 2], output_scale_factor: f32, sample_count: u32, output_color_format: TextureFormat, depth_format: TextureFormat, glyph_cache_size: [u32; 2], glyph_cache_scale_tolerance: f32, glyph_cache_position_tolerance: f32 ) -> Self

Create a new Renderer, ready to target an output attachment with the given size, sample count and color format.

See the RendererBuilder type for a simplified approach to building a renderer that will fall back to a set of reasonable defaults.

The depth_format will be used to construct a depth texture for depth testing.

The glyph_cache_size will be used to create a texture on which glyphs will be stored for efficient look-up.

pub fn clear(&mut self)

Clear all pending render commands vertex data.

pub fn fill( &mut self, device: &Device, draw: &Draw, scale_factor: f32, output_attachment_size: [u32; 2] )

Generate a list of RenderCommands from the given Draw instance and prepare any necessary vertex data.

Note that the given Draw instance will be drained of its commands.

pub fn encode_render_pass( &mut self, device: &Device, encoder: &mut CommandEncoder, draw: &Draw, scale_factor: f32, output_attachment_size: [u32; 2], output_attachment: &TextureView, resolve_target: Option<&TextureView> )

Encode a render pass with the given Drawing to the given output_attachment.

If the Drawing has been scaled for handling DPI, specify the necessary scale_factor for scaling back to the output_attachment_size (physical dimensions).

If the output_attachment is multisampled and should be resolved to another texture, include the resolve_target.

pub fn render_to_texture( &mut self, device: &Device, encoder: &mut CommandEncoder, draw: &Draw, texture: &Texture )

Encode the necessary commands to render the contents of the given Drawing to the given Texture.

pub fn render_to_frame( &mut self, device: &Device, draw: &Draw, scale_factor: f32, frame: &Frame<'_> )

Encode the necessary commands to render the contents of the given Drawing to the given Frame.

Trait Implementations

impl Debug for Renderer

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
