wgpu 纹理图集实现,用于缓存和渲染纹理

Implementations§

Source§

impl WgpuAtlas

Source

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

创建新的纹理图集

Source

pub fn from_context(context: &WgpuContext) -> Self

从 WgpuContext 创建纹理图集

Source

pub fn before_frame(&self)

在每帧渲染前刷新待上传的纹理数据

Source

pub fn get_texture_info(&self, id: AtlasTextureId) -> WgpuTextureInfo

获取指定纹理 ID 的纹理信息

Source

pub fn clear(&self)

清除所有缓存的纹理和图块,强制它们重新创建。 当设备仍然有效时,用于增量恢复。

Source

pub fn handle_device_lost(&self, context: &WgpuContext)

处理设备丢失,清除所有纹理和缓存的图块。 图集将在后续帧中按需惰性重新创建纹理。
