Struct GpuImplicitItem 

#[non_exhaustive]
pub struct GpuImplicitItem {
    pub primitives: Vec<ImplicitPrimitive>,
    pub blend_mode: ImplicitBlendMode,
    pub march_options: GpuImplicitOptions,
    pub id: u64,
    pub appearance: AppearanceSettings,
    pub selected: bool,
}

One GPU implicit surface draw item submitted via [SceneFrame::gpu_implicit].

Up to 16 ImplicitPrimitive entries are supported per item.

Example

use viewport_lib::{GpuImplicitItem, GpuImplicitOptions, ImplicitBlendMode, ImplicitPrimitive};

let mut prim = ImplicitPrimitive::zeroed();
prim.kind   = 1;  // sphere
prim.blend  = 0.9;
prim.params = [0.0, 0.0, 0.0, 1.0, 0.0, 0.0, 0.0, 0.0];  // center=origin, radius=1
prim.colour  = [1.0, 0.5, 0.2, 1.0];

let mut item = GpuImplicitItem::default();
item.primitives    = vec![prim];
item.blend_mode    = ImplicitBlendMode::SmoothUnion;
item.march_options = GpuImplicitOptions::default();

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.

primitives: Vec<ImplicitPrimitive>

Primitive descriptors (max 16 entries; excess entries are ignored).

blend_mode: ImplicitBlendMode

How the primitives are combined.

march_options: GpuImplicitOptions

Ray-march quality settings.

id: u64

Pick ID for unified selection API. 0 = not selectable.

appearance: AppearanceSettings

Per-item appearance overrides (hidden, unlit, opacity, wireframe).

selected: bool

If true, draws an outline ring around the implicit surface.

Trait Implementations

impl Default for GpuImplicitItem

fn default() -> Self

Returns the “default value” for a type.
