Struct SingleSliceEngine 

pub struct SingleSliceEngine { /* private fields */ }

Lightweight single-canvas renderer for stack (2D) viewing.

Unlike RenderEngine which manages 4 viewports, this engine renders a single slice viewport into one canvas. It uses the same underlying VolumeRenderer and IncrementalVolume for data storage and GPU-accelerated reslicing.

Implementations

impl SingleSliceEngine

pub fn new(device: &Device, queue: &Queue, output_format: TextureFormat) -> Self

Creates a single-slice renderer targeting the provided output format.

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

Creates a single-slice renderer from shared Arc handles.

pub fn prepare_volume( &mut self, geometry: VolumeGeometry, ) -> Result<(), RenderEngineError>

Prepares an empty progressive volume and allocates its GPU texture.

pub fn insert_slice( &mut self, z_index: u32, pixels: &[i16], ) -> Result<(), RenderEngineError>

Inserts one slice into the progressive volume and uploads it to the GPU.

pub fn prepared_volume(&self) -> Option<&IncrementalVolume>

Returns the prepared progressive volume, if any.

pub fn slice_state_mut(&mut self) -> &mut SlicePreviewState

Returns mutable access to the slice viewport state.

pub fn scalar_range(&self) -> Option<(f64, f64)>

Returns the currently known scalar range.

pub fn set_slice_mode(&mut self, mode: SlicePreviewMode)

Switches which orthogonal plane is displayed.

pub fn scroll_slice(&mut self, delta: f64) -> Result<(), RenderEngineError>

Scrolls the slice along its normal.

pub fn set_window_level( &mut self, center: f64, width: f64, ) -> Result<(), RenderEngineError>

Applies a transfer window to the slice viewport.

pub fn reset(&mut self)

Resets the slice viewport state.

pub fn render_slice( &mut self, encoder: &mut CommandEncoder, target: &RenderTarget<'_>, ) -> Result<(), RenderEngineError>

Renders the single slice into the provided target.
