Struct ImageSliceItem

    pub volume_id: VolumeId,

Expand description

A 2D image slice item: renders one axis-aligned cross-section of an uploaded volume as a flat coloured quad.

Faster and simpler than full volume ray-marching. Use it to inspect individual slices of a structured grid without the depth ambiguity of ray-marching.

Fields (Non-exhaustive)§

This struct is marked as non-exhaustive
Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.
§volume_id: VolumeId

Reference to a previously uploaded 3D volume texture.

§axis: SliceAxis

Axis perpendicular to the slice plane. Default: SliceAxis::Z.

§offset: f32

Normalized position along the axis in [0, 1]. Default: 0.5.

§bbox_min: [f32; 3]

World-space bounding box minimum corner of the volume.

§bbox_max: [f32; 3]

World-space bounding box maximum corner of the volume.

§scalar_range: (f32, f32)

Scalar range for colourmap mapping [min, max]. Default: (0.0, 1.0).

§colour_lut: Option<ColourmapId>

Colour LUT. None = default builtin (viridis).

§opacity: f32

Overall opacity of the slice quad. Default: 1.0.

§id: u64

Pick ID for unified selection API. 0 = not selectable.

§appearance: AppearanceSettings

Per-item appearance overrides (hidden, unlit, opacity, wireframe).

§selected: bool

If true, draws an outline ring around the slice quad.
