NAME
MPSIntersectionDistancePrimitiveIndex - Intersection result which contains the distance from the ray origin to the intersection point and the index of the intersected primitive.
SYNOPSIS
#include <MPSRayIntersectorTypes.h>
Public Attributes
float distance
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. unsigned int primitiveIndex
Index of the intersected primitive. Undefined if the ray does not intersect a
primitive or if the intersection type is MPSIntersectionTypeAny.
Detailed Description
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.

float MPSIntersectionDistancePrimitiveIndex::distance
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.
unsigned int MPSIntersectionDistancePrimitiveIndex::primitiveIndex
Index of the intersected primitive. Undefined if the ray does not intersect a primitive or if the intersection type is MPSIntersectionTypeAny.
