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.
§positions: Vec<[f32; 3]>

World-space positions (one vec3 per point).

§colors: Vec<[f32; 4]>

Optional per-point RGBA colors in linear [0,1]. If empty, uses default_color.

§scalars: Vec<f32>

Optional per-point scalar values for LUT coloring. If non-empty, overrides colors.

§scalar_range: Option<(f32, f32)>

Scalar range for LUT mapping. None = auto from min/max of scalars.

§colormap_id: Option<ColormapId>

Colormap for scalar coloring. None = use default builtin (viridis).

§point_size: f32

Screen-space point size in pixels. Default: 4.0.

§default_color: [f32; 4]

Fallback color when neither colors nor scalars are provided.

§model: [[f32; 4]; 4]

World-space model matrix. Default: identity.

§render_mode: PointRenderMode

Render mode. Default: ScreenSpaceCircle.

§id: u64

Unique ID for picking. 0 = not pickable.

§radii: Vec<f32>

Optional per-point radii in pixels. If non-empty, overrides point_size for each point.

§transparencies: Vec<f32>

Optional per-point opacity values in [0, 1]. If non-empty, scales each point’s alpha.
