Locatable Camera sample code bug?

memcpymemcpy ✭
in Questions And Answers

I was using the UnProjectVector sample code from https://developer.microsoft.com/en-us/windows/holographic/locatable_camera and noticed a potential bug.

It appears that the camera position information is lost during matrix multiplication for the WorldSpaceRayPoint2 calculation.

** float3 WorldSpaceRayPoint2 = mul( CameraToWorld, CameraSpacePos ); // ray point in world space**
should be
float3 WorldSpaceRayPoint2 = mul( CameraToWorld, float4(CameraSpacePos, 1) ); // ray point in world space
