Trait Implementations

impl<S: Clone, M: Clone> Clone for ShapedPrimitive<S, M>

fn clone(&self) -> ShapedPrimitive<S, M>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<S, M> Composable for ShapedPrimitive<S, M> where
    S: Shape,
    M: Material, 

fn bbox_parent(&self) -> BBox3f

returns bounding box in parent frame.

fn intersect_ray(&self, ray: &mut RawRay) -> Option<SurfaceInteraction>

test for intersection. Note that its guarantees are from Shape's: - ray is specified in parent frame, - if hit, returns surface interaction data in parent frame. - if hit, ray's tmax would be updated to the hitting t.

fn can_intersect(&self, ray: &RawRay) -> bool

test if an intersection can occur. Might be more efficient

fn as_light(&self) -> &Light

fn intersection_cost(&self) -> Float

impl<S, M> Light for ShapedPrimitive<S, M> where
    S: Shape,
    M: Material, 

fn flags(&self) -> LightFlag

return the flags of the light

fn is_delta(&self) -> bool

test if the light has delta distribution

fn evaluate_path(&self, pos: Point3f, dir: Vector3f) -> RGBSpectrumf

Given a position on surface and an direction in local coordinates, evaluate the light's emitted radiance along that direction.

fn evaluate_sampled(&self, pos: Point3f, sample: Point2f) -> LightSample

Given a surface pos and norm in local frame with a uniform sample in $[0, 1)$, sample an incoming direction from the light to that location, returns the sampling result in a LightSample.

fn generate_path(&self, samples: SampleInfo) -> PathInfo

Generate a photon path from the light source based on the sample info

fn pdf_path(
    &self,
    pos: Point3f,
    dir: Vector3f,
    norm: Vector3f
) -> (Float, Float)

Given position and direction of a photon path, and the light's normal return its pdfs as (pdfpos, pdfdir)

fn pdf(&self, pos: Point3f, wi: Vector3f) -> Float

Given a position and lighting ray wi of an interaction, return the pdf of it

fn power(&self) -> RGBSpectrumf

returns an estimation of total power of this light

fn evaluate_ray(&self, rd: &RayDifferential) -> RGBSpectrumf

Given a position and an incoming direction in local coordinates, evaluate the light's radiance along that direction. This method takes an RayDifferential because some light implementations might found thouse differentials helpful.

fn preprocess(&mut self, _s: &Scene)

preporcess with scene components, if necessary. renderers should respect this requirement.

impl<S, M> Primitive for ShapedPrimitive<S, M> where
    S: Shape,
    M: Material, 

fn get_material(&self) -> &Material

return the material associated with this primitive

fn is_emissive(&self) -> bool

return if the primitive can emit lights
