Implementations

impl BlendRenderer

pub fn new( device: Arc<Device>, queue: Arc<Queue>, texture_format: TextureFormat, ) -> Result<Self>

Create a new blend renderer.

fn is_cached(&self, key_a: usize, key_b: usize) -> bool

Check if cached bind group matches texture pair

fn get_cached_bind_group(&self) -> Option<&BindGroup>

Get or create a cached bind group for the texture pair.

fn create_and_cache_bind_group( &mut self, texture_a: &TextureView, texture_b: &TextureView, )

Create and cache a new bind group for the texture pair.

pub fn render( &mut self, texture_a: &TextureView, texture_b: &TextureView, output: &TextureView, blend_pattern: u32, blend_amount: f32, time: f32, ) -> Result<()>

Render blended output.
