Member Enumeration Documentation

anonymous enum

The type of the underlying object against which the hit testing occurred; triObject for Mesh, polyObject for MNMesh, and patchObject for PatchMesh.

The empty type indicates that no hit testing has been performed yet

Enumerator
empty
triObject
polyObject
patchObject

{ empty=0, triObject, polyObject, patchObject } type;

Constructor & Destructor Documentation

CoreExport HitListWrapper ( )

inline

Remarks

Constructor. This does not call the Init() method, so wrapper must still be initialized before it can be used.

{type=empty;}

CoreExport ~HitListWrapper

(

)

Remarks

Destructor. Deallocates used memory by calling Release()

Member Function Documentation

CoreExport bool GoToFirst

(

)

Remarks

Sets the first hit entry in the list as the current hit

Returns

FALSE if no hit entries are in the list, otherwise TRUE

CoreExport bool GoToNext

(

)

Remarks

Sets the current hit to the next entry in the list

Returns

FALSE if the operation fails because no entries remain the list, otherwise TRUE

CoreExport DWORD GetDist

(

)

Remarks

The distance of the current hit. If the user is in wireframe mode, this is the distance in pixels to the item that was hit. If the user is in shaded mode, this is the Z depth distance. Smaller numbers indicate a closer hit.

Returns

The distance of the current hit.

CoreExport int GetIndex

(

)

Remarks

The index of the sub-object component of the current hit. For example, if faces were being hit tested, this would be the index of the face which was hit.

Returns

The index of the sub-object component of the current hit.

CoreExport void Init

(

int

type

)

Remarks

Initializes the wrapper to the specified object type, allocating the type-specific hit list used by the wrapper. This must be called before the wrapper can store any hit test results.

Parameters

type	- one of the type enum values

CoreExport void Release

(

)

Remarks

Releases the type-specific hit list used by the wrapper. This is normally called by the destructor.
