Struct MPSIntersectionDistance 

#[repr(C)]
pub struct MPSIntersectionDistance {
    pub distance: c_float,
}

Available on crate features MPSRayIntersector and MPSRayIntersectorTypes only.

Returned intersection result which contains the distance from the ray origin to the intersection point

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.

Trait Implementations

impl Clone for MPSIntersectionDistance

fn clone(&self) -> MPSIntersectionDistance

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MPSIntersectionDistance

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

Formats the value using the given formatter.

impl Encode for MPSIntersectionDistance

const ENCODING: Encoding

The Objective-C type-encoding for this type.

impl PartialEq for MPSIntersectionDistance

fn eq(&self, other: &MPSIntersectionDistance) -> 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 MPSIntersectionDistance

const ENCODING_REF: Encoding

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

impl Copy for MPSIntersectionDistance

impl StructuralPartialEq for MPSIntersectionDistance
