Struct MPSIntersectionDistancePrimitiveIndex 

#[repr(C)]
pub struct MPSIntersectionDistancePrimitiveIndex {
    pub distance: c_float,
    pub primitiveIndex: c_uint,
}

Available on crate features MPSRayIntersector and MPSRayIntersectorTypes only.

Intersection result which contains the distance from the ray origin to the intersection point and the index of the intersected primitive

This type is available from the Metal Shading Language by including the MetalPerformanceShaders/MetalPerformanceShaders.h header.

See also Apple’s documentation

Fields

distance: c_float

Distance from the ray origin to the intersection point along the ray direction vector such that intersection = ray.origin + ray.direction * distance. Is negative if there is no intersection. If the intersection type is MPSIntersectionTypeAny, is a positive value for a hit or a negative value for a miss.

primitiveIndex: c_uint

Index of the intersected primitive. Undefined if the ray does not intersect a primitive or if the intersection type is MPSIntersectionTypeAny.

Trait Implementations

impl Clone for MPSIntersectionDistancePrimitiveIndex

fn clone(&self) -> MPSIntersectionDistancePrimitiveIndex

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MPSIntersectionDistancePrimitiveIndex

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Encode for MPSIntersectionDistancePrimitiveIndex

const ENCODING: Encoding

The Objective-C type-encoding for this type.

impl PartialEq for MPSIntersectionDistancePrimitiveIndex

fn eq(&self, other: &MPSIntersectionDistancePrimitiveIndex) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl RefEncode for MPSIntersectionDistancePrimitiveIndex

const ENCODING_REF: Encoding

The Objective-C type-encoding for a reference of this type.

impl Copy for MPSIntersectionDistancePrimitiveIndex
