Struct StreamtubeItem 

#[non_exhaustive]
pub struct StreamtubeItem {
    pub positions: Vec<[f32; 3]>,
    pub strip_lengths: Vec<u32>,
    pub radius: f32,
    pub color: [f32; 4],
    pub id: u64,
}

A streamtube item: polyline strips rendered as instanced 3D cylinder segments.

Each consecutive pair of positions within a strip becomes one cylinder instance, oriented along the segment direction, scaled to the configured radius. The cylinder mesh is an 8-sided built-in uploaded once at pipeline creation time.

StreamtubeItem is #[non_exhaustive] so future fields (e.g. per-point radius from a scalar attribute) can be added without breaking existing callers.

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.

positions: Vec<[f32; 3]>

World-space positions for all strips, concatenated.

strip_lengths: Vec<u32>

Number of vertices per individual strip.

radius: f32

Tube radius in world-space units. Default: 0.05.

color: [f32; 4]

RGBA colour for all tube segments in this item. Default: opaque white.

id: u64

Unique ID (reserved for future picking support). Default: 0.
