intersectRayWithTerrain
public static Position intersectRayWithTerrain(Globe globe,
Vec4 origin,
Vec4 direction)
- Compute the intersection
Position of the globe terrain with the ray starting
at origin in the given direction. Uses default sample length and result precision.
- Parameters:
globe - the globe to intersect with.origin - origin of the ray.direction - direction of the ray.
- Returns:
- the
Position found or null.
intersectRayWithTerrain
public static Position intersectRayWithTerrain(Globe globe,
Vec4 origin,
Vec4 direction,
double sampleLength,
double precision)

Position of the globe terrain with the ray starting
at origin in the given direction. Uses the given sample length and result precision.
- Parameters:
globe - the globe to intersect with.origin - origin of the ray.direction - direction of the ray.sampleLength - the sampling step length in meters.precision - the maximum sampling error in meters.
- Returns:
- the
Position found or null.
intersectSegmentWithTerrain
public static Vec4 intersectSegmentWithTerrain(Globe globe,
Vec4 p1,
