Expand description

Per-object render data for one frame.

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.
§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.
