Struct RenderEngine 

pub struct RenderEngine { /* private fields */ }

Shared renderer and viewport state for the four-canvas layout.

Implementations

impl RenderEngine

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

Creates a renderer that targets the provided output format.

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

Creates a renderer from shared Arc device and queue 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 geometry(&self) -> Option<VolumeGeometry>

Returns the active volume geometry, if any.

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

Returns the currently known scalar range.

pub fn volume_state_mut(&mut self) -> &mut VolumeViewState

Returns mutable access to the volume viewport state.

pub fn slice_state_mut( &mut self, mode: SlicePreviewMode, ) -> &mut SlicePreviewState

Returns mutable access to one slice viewport state.

pub fn slice_state(&self, mode: SlicePreviewMode) -> &SlicePreviewState

Returns immutable access to one slice viewport state.

pub fn set_volume_preset(&mut self, preset_id: VolumePresetId)

Sets the active volume-rendering preset.

pub fn set_crosshair(&mut self, world: DVec3) -> Result<(), RenderEngineError>

Moves the shared MPR crosshair and centers all slice views on that point.

pub fn set_crosshair_from_viewport( &mut self, mode: SlicePreviewMode, uv: DVec2, viewport: Viewport, ) -> Result<(), RenderEngineError>

Moves the shared MPR crosshair from one viewport-relative point.

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

Scrolls one slice viewport along its normal.

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

Applies one transfer window to all viewports.

pub fn set_thick_slab( &mut self, mode: SlicePreviewMode, thickness: f64, projection_mode: SliceProjectionMode, )

Configures the thick-slab mode for one slice viewport.

pub fn reset(&mut self)

Resets all viewports back to their default interaction state.

pub fn render_frame( &mut self, encoder: &mut CommandEncoder, targets: FrameTargets<'_>, show_crosshairs: bool, ) -> Result<(), RenderEngineError>

Renders the four-view layout into the provided targets.
