C++ (Cpp) createSlice Examples

Example #1

File: types.cpp Project: wangxianke/pyston

extern "C" Box* sliceNew(Box* cls, Box* start, Box* stop, Box** args) {
    RELEASE_ASSERT(cls == slice_cls, "");
    Box* step = args[0];

    if (stop == NULL)
        return createSlice(None, start, None);
    return createSlice(start, stop, step);
}

Example #2

File: vtkRegionGrowing.cpp Project: mrajchl/hierarchicalmaxflowgui

void vtkRegionGrowing::Start()
{
	
mVolume->GetExtent(mExt);
createSlice();


int n=mSeeds.size();
for(int i=0; i<n; i++)mQueue.push(mSeeds[i]);

if(mOrientation==0)processX();
if(mOrientation==1)processY();
if(mOrientation==2)processZ();

copySlice();
mSlice->Delete();	
}
