Ray Ecuation? (collision-response)

1)
public Ray (
Vector3 position, //Begin vector
Vector3 direction //End position vector

Is really Directional vector

position (x0,y0,z0)------------->(x1,y1,z1);

2) Ray.Intesect(xx) return a float value .. what is its ecuation

could be its use like magnitude of a vector of overlapping between two shapes

THK!! :)

The direction is a unit vector represents the ray direction.

If the return value is zero, it means the ray origin is inside the bounding volume. If the return value is null, it means the ray doesn't intersect with the volume. The positive value is the distance from the origin to the intersection point. You can calculate the intersecting point by = position + (direction * distance)
