Per-object render data for one frame.

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.

mesh_index: usize

Index into ViewportGpuResources::meshes for this object’s GPU buffers.

model: [[f32; 4]; 4]

World-space model matrix (Translation * Rotation * Scale).

selected: bool

Whether this object is selected (drives orange tint in WGSL).

visible: bool

Whether this object is visible. Hidden objects are not drawn.

show_normals: bool

Whether to render per-vertex normal visualization lines for this object.

material: Material

Per-object material (color, shading coefficients, opacity, texture).

active_attribute: Option<AttributeRef>

Named scalar attribute to colour by. None = use material base colour.

scalar_range: Option<(f32, f32)>

Explicit scalar range (min, max). None = use auto-range computed at upload time.

colormap_id: Option<ColormapId>

Colormap to use for scalar colouring. Ignored when active_attribute is None.

nan_color: Option<[f32; 4]>

RGBA color for NaN scalar values. None = discard (fully transparent).

two_sided: bool

Render this mesh with no back-face culling (visible from both sides).

Set this for analytical surfaces (plots, CFD isosurfaces) that the camera can orbit under. Opaque geometry with this flag uses the solid_two_sided_pipeline instead of solid_pipeline.

pick_id: u64

GPU pick identifier for this surface. 0 = not pickable.

The renderer only includes surfaces with a nonzero pick_id in the GPU pick pass. Set a nonzero value for any surface the user should be able to click to select. Helper geometry and transient previews that should not participate in picking should leave this at the default 0.

Trait Implementations

impl Clone for SceneRenderItem

fn clone(&self) -> SceneRenderItem
