Classes
struct	DtBulletRayResultCallback
	Base class for bullet callbacks which implements needsCollision. More...
struct	DtBulletRayResultCallback::RayResultRecord
	Holds hit results so that data we need from them can be computed after mutex has been released. More...
struct	DtAllHitsRayResultCallback
	Extended version of bullet's RayResultCallback which records all the hits along the ray instead of only the closest one. More...
struct	DtClosestRayResultCallback
	Only records the closest hit. More...
struct	DtIntersectionExistsCallback
	Only records whether there was a hit or not, bails out of future calculations once it finds one. More...

Functions

bool DT_DLL_vantageTerrainImplementation	shapeSphereVolumetricIntersect (const Coordinate_System &, const DtLocalVertexList &shape, const DtSphere &sphere)
	Note that this function treats the shape as if it is in two dimensions (all tests ignore height for the sphere and the vertices). More...

bool DT_DLL_vantageTerrainImplementation	DtIntersectRaySphere2 (const DtPoint &rayStartPoint, const DtVector &rayDirectionNonNormalized, const DtSphere &sphere, double &t)
	Almost the same function DtIntersectRaySphere in makTerrainToolkit But removing a few lines of code since in some case we don't need intersection points and segment chord. More...

bool DT_DLL_vantageTerrainImplementation btVectorIsZero

const btVector3 &

bool DT_DLL_vantageTerrainImplementation chordSphereVolumetricIntersect	(	const DtChord &	chord,
		const DtSphere &	sphere
	)

Returns

True if the specified chord intersects with the volume defined by sphere. The chord may be wholly contained within the sphere, and this will return true.

bool DT_DLL_vantageTerrainImplementation sphereSphereVolumetricIntersect	(	const DtSphere &	sphere1,
		const DtSphere &	sphere2
	)

Returns

True if the two spheres intersect. One sphere may be wholly contained within the other sphere, and this will return true.

bool DT_DLL_vantageTerrainImplementation shapeSphereVolumetricIntersect	(	const Coordinate_System &	,
		const DtLocalVertexList &	shape,
		const DtSphere &	sphere
	)

Note that this function treats the shape as if it is in two dimensions (all tests ignore height for the sphere and the vertices).

Returns

True if the shape intersects the sphere. This means that either the center of the sphere is within the shape, or the center of the sphere is within its own radius of the nearest point on the shape.

bool DT_DLL_vantageTerrainImplementation geometrySphereVolumetricIntersect	(	const Coordinate_System &	,
		DtTerrainPagingGeometryPtr	geometry,
		const DtSphere &	sphere
	)

Returns

True if the sphere overlaps the geometry defined in the geometry pointer. Uses the above volumetric intersect functions to do the intersection.

bool DT_DLL_vantageTerrainImplementation DtIntersectRaySphere2	(	const DtPoint &	rayStartPoint,
		const DtVector &	rayDirectionNonNormalized,
		const DtSphere &	sphere,
		double &	t
	)

Almost the same function DtIntersectRaySphere in makTerrainToolkit But removing a few lines of code since in some case we don't need intersection points and segment chord.
