Template:Wrongtitle A structure that has a starting point, a direction and a length that represents a line that has a starting point, and extends infinitely in one direction.

```
VectorAligned m_Start; // starting point, centered within the extents
VectorAligned m_Delta; // direction + length of the ray
VectorAligned m_StartOffset; // Add this to m_Start to get the actual ray start
VectorAligned m_Extents; // Describes an axis aligned box extruded along a ray
bool m_IsRay; // are the extents zero?
bool m_IsSwept; // is delta != 0?
```
