Struct ClipVolumeEntry 

pub struct ClipVolumeEntry {
    pub volume_type: u32,
    pub center: [f32; 3],
    pub radius: f32,
    pub half_extents: [f32; 3],
    pub col0: [f32; 3],
    pub col1: [f32; 3],
    pub col2: [f32; 3],
    /* private fields */
}

One entry in the clip-volume uniform array : 96 bytes.

volume_type selects the active shape:

• 0 = None (slot unused)
• 2 = Box (oriented AABB : center, half-extents, three orientation columns)
• 3 = Sphere (center + radius packed into center and radius)

Layout mirrors the WGSL ClipVolumeEntry struct in each geometry shader.

Fields

volume_type: u32

Shape discriminant: 0=None, 2=Box, 3=Sphere.

center: [f32; 3]

Box center (world space) or sphere center. Occupies the xyz components.

radius: f32

Sphere radius. Unused for boxes.

half_extents: [f32; 3]

Box half-extents. Unused for spheres.

col0: [f32; 3]

Box local X axis (orientation column 0, world space). Unused for spheres.

col1: [f32; 3]

Box local Y axis (orientation column 1, world space). Unused for spheres.

col2: [f32; 3]

Box local Z axis (orientation column 2, world space). Unused for spheres.

Implementations

impl ClipVolumeEntry

pub fn from_box( center: [f32; 3], half_extents: [f32; 3], orientation: [[f32; 3]; 3], ) -> Self

Build a box entry from center, half-extents, and orientation columns.

pub fn from_sphere(center: [f32; 3], radius: f32) -> Self

Build a sphere entry from center and radius.

pub fn from_cylinder( center: [f32; 3], axis: [f32; 3], radius: f32, half_length: f32, ) -> Self

Build a cylinder entry from center, unit axis, radius, and half-length.

The cylinder extends half_length units in each direction along axis from center. axis must be a unit vector.
