RTC_GEOMETRY_TYPE_SPHERE_POINT geometry in 3.4

RTC_GEOMETRY_TYPE_SPHERE_POINT geometry in 3.4


Hi,

I am wanting to use the new  RTC_GEOMETRY_TYPE_SPHERE_POINT in embree 3.4. However it's unclear to me what is returned in the RayHit structure for a sphere hit? What does u,v mean for a sphere?

The hit distance and geometry normal field are set for the point geometry, u and v are set to zero. In particular the returned normal can get used to calculate coordinates for your sphere parametrization of choice.


OK, makes sense thanks!
