Struct SceneFrame 

#[non_exhaustive]
pub struct SceneFrame {
    pub generation: u64,
    pub surfaces: SurfaceSubmission,
    pub point_clouds: Vec<PointCloudItem>,
    pub glyphs: Vec<GlyphItem>,
    pub polylines: Vec<PolylineItem>,
    pub volumes: Vec<VolumeItem>,
    pub isolines: Vec<IsolineItem>,
    pub streamtube_items: Vec<StreamtubeItem>,
}

World-space scene content for one frame.

Groups all renderable world-space content submitted to the renderer. Surfaces are submitted through the SurfaceSubmission seam; scientific visualization primitives are first-class members alongside surfaces.

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.

generation: u64

Scene version counter from Scene::version(). Default: 0 (triggers rebuild on first frame).

The renderer uses this to skip batch rebuild and GPU upload when scene content has not changed since the previous frame.

surfaces: SurfaceSubmission

Surface geometry submission (opaque and transparent meshes).

point_clouds: Vec<PointCloudItem>

Point cloud items to render this frame.

glyphs: Vec<GlyphItem>

Instanced glyph items to render this frame.

polylines: Vec<PolylineItem>

Polyline (streamline) items to render this frame.

volumes: Vec<VolumeItem>

Volume items to render this frame via GPU ray-marching.

isolines: Vec<IsolineItem>

Isoline (contour line) items to render on mesh surfaces.

streamtube_items: Vec<StreamtubeItem>

Streamtube items to render this frame.

Implementations

impl SceneFrame

pub fn new(surfaces: SurfaceSubmission) -> Self

Build a scene frame from a surface submission.

pub fn from_surface_items(items: Vec<SceneRenderItem>) -> Self

Build a scene frame from a flat list of surface render items.

Trait Implementations

impl Default for SceneFrame

fn default() -> Self

Returns the “default value” for a type.
