Struct ImplicitPrimitive 

pub struct ImplicitPrimitive {
    pub kind: u32,
    pub blend: f32,
    pub params: [f32; 8],
    pub color: [f32; 4],
    /* private fields */
}

Primitive descriptor for the GPU implicit SDF.

The shader evaluates each primitive independently and combines them according to the item’s ImplicitBlendMode.

Primitive kinds and params layout

kind	Primitive	params[0..4]	params[4..8]
1	Sphere	cx,cy,cz,radius	unused
2	Box	cx,cy,cz,_	hx,hy,hz,_ (half-extents)
3	Plane	nx,ny,nz,d	unused (normal + offset)
4	Capsule	ax,ay,az,radius	bx,by,bz,_ (endpoints)

Fields

kind: u32

Primitive type discriminant (1=sphere, 2=box, 3=plane, 4=capsule).

blend: f32

Smooth-min blend radius used when the item’s blend mode is SmoothUnion. Zero produces a hard union.

params: [f32; 8]

Kind-specific parameters, first four floats.

color: [f32; 4]

Linear RGBA colour for this primitive. Colours are blended by proximity weight at the hit point.
