Struct ImageSliceItem 

#[non_exhaustive]
pub struct ImageSliceItem {
    pub volume_id: VolumeId,
    pub axis: SliceAxis,
    pub offset: f32,
    pub bbox_min: [f32; 3],
    pub bbox_max: [f32; 3],
    pub scalar_range: (f32, f32),
    pub color_lut: Option<ColormapId>,
    pub opacity: f32,
}

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

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 colormap mapping [min, max]. Default: (0.0, 1.0).

color_lut: Option<ColormapId>

Color LUT. None = default builtin (viridis).

opacity: f32

Overall opacity of the slice quad. Default: 1.0.
