Detailed Description

The ray hit information. The ray hit contains the information from the result of a ray casting operation. This includes the body and geometry that terminated the raycast, as well as the position and normal of the hit location, and the distance from the origin of the initial ray cast operation. Each engine may not support the full set of raycast information, so each variable should be checked for validity. This can be done via the m_bHit, m_bHitPosition, and m_bHitNormal flags. Example:

palRayHit *prh;
if (prh->m_bHit)
	prh->m_vHitPosition.x //do a calculation

Raycasting allows the implementation of AI functionality and the simulation of distance sensors (eg: PSD or Sonar)
