MPSIntersectionDistance - Returned intersection result which contains the distance from the ray origin to the intersection point.
#include <MPSRayIntersectorTypes.h>
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.
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.
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.
