int* SUMA_SURF_PLANE_INTERSECT::IntersEdges

Vector containing indices of edges intersected by the plane. The indices are into SO->EL->EL matrix. The space allocate for this vector is SO->EL->N_EL But that is way more than ususally needed. For this vector and others in this structure, reallocation is not done to save time. Useful values for IntersEdges are between IntersEdges[0] and IntersEdges[N_IntersEdges-1]

float* SUMA_SURF_PLANE_INTERSECT::IntersNodes

Vector containing XYZ coordinates of the intersection point on each intersected segment. Allocated space is for 3*SO->EL->N_EL, meaningful values are for intersected segments only. Intersection point of edge SO->EL->EL[k][:] has X = IntersNodes[3*k], Y = IntersNodes[3*k+1] and Z = IntersNodes[3*k+2]

int* SUMA_SURF_PLANE_INTERSECT::IntersTri

Vector containing indices of triangles intersected by the plane (i.e. containing and edge that was intersected. Allocation is done for SO->N_FaceSet. But meaningful values are between IntersETri[0] and IntersTri[N_IntersTri-1].

SUMA_Boolean* SUMA_SURF_PLANE_INTERSECT::isEdgeInters

Vector specifying if an edge i (index into SO->EL->EL) was intersected.

SUMA_Boolean* SUMA_SURF_PLANE_INTERSECT::isNodeInMesh

Vector of SO->N_Node elements indicating whether a certain node belongs to an intersected seqment or not

SUMA_Boolean* SUMA_SURF_PLANE_INTERSECT::isTriHit

Vector of SO->N_FaceSet elements indicating whether a triangle was intersected by the plane. if isTriHit[j] then triangle SO->FaceSetList[3*j], [3*j+1], [3*j+2] was intersected. You should have a total of N_IntersTri YUP values in this vector
