Struct Occluder 

pub struct Occluder { /* private fields */ }

A ray-traceable geometric surface with an attached material.

Implementations

impl Occluder

Implements factory constructors for Occluder.

pub fn sphere(center: Vector3D, radius: f64, material: Material) -> Occluder

Creates a spherical occluder centered at center with radius.

Arguments

• Vector3D - The sphere center.
• f64 - The sphere radius.
• Material - The surface material.

Returns

• Occluder - The new sphere occluder.

pub fn aabb(min: Vector3D, max: Vector3D, material: Material) -> Occluder

Creates an axis-aligned bounding-box occluder from min to max.

Arguments

• Vector3D - The AABB minimum corner.
• Vector3D - The AABB maximum corner.
• Material - The surface material.

Returns

• Occluder - The new AABB occluder.

pub fn triangle( v0: Vector3D, v1: Vector3D, v2: Vector3D, material: Material, ) -> Occluder

Creates a triangular occluder from its three vertices.

The vertex order fixes the geometric winding; because the intersection test is two-sided the winding does not affect which faces produce hits, only the raw cross-product normal before it is oriented against the incoming ray.

Arguments

• Vector3D - The first triangle vertex.
• Vector3D - The second triangle vertex.
• Vector3D - The third triangle vertex.
• Material - The surface material.

Returns

• Occluder - The new triangle occluder.

pub fn occluder_points(&self) -> Vec<(Vector3D, f64)>

Returns a list of (center, radius) sphere tuples approximating this occluder, suitable for soft_shadow_factor.

For sphere occluders this returns (center, radius). For AABB occluders the bounding sphere is computed conservatively from the AABB extents.

Returns

• Vec<(Vector3D, f64)> - One bounding sphere per occluder.
