Struct Atlas

pub struct Atlas {
    pub extent_buf: Buffer,
    pub mvp: Buffer,
    pub view: Arc<TextureView>,
    pub targets: Vec<TextureView>,
    /* private fields */
}

Array of 2D textures, along with an array of guillotine allocators to go along with them. We use an array of mid-size textures so we don’t have to resize the atlas allocator or adjust any UV coordinates that way.

Fields

extent_buf: Buffer

mvp: Buffer

view: Arc<TextureView>

targets: Vec<TextureView>

Implementations

impl Atlas

pub fn resize(&mut self, device: &Device, queue: &Queue, layers: u32)

Creates an encoder that resizes the texture atlas, submits this to the work queue. Does not wait until queue finishes processing as this shouldn’t be necessary.

pub fn create_mvp_from_texture( device: &Device, texture: &Texture, name: &str, ) -> Buffer

Create a standard projection matrix suitable for compositing for a texture.

pub fn new(device: &Device, extent: u32, kind: AtlasKind) -> Self

pub fn get_texture(&self) -> &Texture

pub fn get_region(&self, id: Arc<SourceID>) -> Option<&Region>

pub fn remove_cache(&mut self, id: &Arc<SourceID>) -> bool

pub fn cache_region( &mut self, device: &Device, id: &Arc<SourceID>, dim: Size, ) -> Result<&Region, Error>

pub fn reserve(&mut self, device: &Device, dim: Size) -> Result<Region, Error>

pub fn destroy(&mut self, region: &mut Region)

pub fn draw(&self, driver: &Driver, encoder: &mut CommandEncoder)

Trait Implementations
