Struct IsolineItem 

#[non_exhaustive]
pub struct IsolineItem {
    pub positions: Vec<[f32; 3]>,
    pub indices: Vec<u32>,
    pub scalars: Vec<f32>,
    pub isovalues: Vec<f32>,
    pub color: [f32; 4],
    pub line_width: f32,
    pub model_matrix: Mat4,
    pub depth_bias: f32,
}

Describes a contour-line extraction request for one mesh / scalar field.

IsolineItem is #[non_exhaustive] so future fields can be added without breaking existing callers that construct it via Default::default() + field assignment.

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]>

Mesh vertex positions in local (object) space. Must be the same length as scalars.

indices: Vec<u32>

Triangle indices into positions. Length must be a multiple of 3.

scalars: Vec<f32>

Per-vertex scalar values for the field to contour. Must be the same length as positions.

isovalues: Vec<f32>

Isovalues at which contour lines are extracted. Each value produces an independent set of line segments.

color: [f32; 4]

RGBA colour applied to every line segment. Defaults to opaque white.

line_width: f32

Line width in pixels. Defaults to 1.0.

model_matrix: Mat4

Model matrix that transforms local-space positions to world space. Defaults to glam::Mat4::IDENTITY.

depth_bias: f32

Small offset along the surface face normal applied to extracted vertices to prevent z-fighting with the underlying mesh. Defaults to 0.001.
