MeshSubHitRec Struct Reference

#include <mesh.h>

Class Description

This class allows access to the sub-object hit records used in Mesh hit testing.

All methods of this class are implemented by the system. SubObjHitList use Tab instead of linked-list in Max 2017 for performance of large amount of data. The constructor's change is to keep code compatibility. Although internal storage changed, client code only needs recompile without any modification.

Constructor & Destructor Documentation

MeshSubHitRec ( DWORD  dist, int  index  )

Constructor.

The data members are initialized to the data members passed.

Parameters

dist	distance of the hit point
index	the sub object's index

    {
        this->dist = dist; this->index = index;
        index2 = -1;
    }

Member Data Documentation

DWORD dist

The distance of the 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.

int index

The index of the sub-object component.

For example, if faces were being hit tested, this would be the index of the mesh's BitArray faceSel. For edges, this is the index into the edgeSel BitArray, where the index is 3*faceIndex+edgeIndex.

int index2

The second level index of the sub-object component.

Usually it is used for MNMesh's diagonal selection, in this case the index is the poly face index while index2 is the diagonal index within the poly face.
