◆ BuildCol() [1/2]

template<class D , class V >
void Rgl::Mc::TMeshBuilder< D, V >::BuildCol ( SliceType_t s) const
private

"Col" (column) consists of cubes along y axis on the first slice (nx == 0, nz == 0).

Each cube has a previous cube and shares values: 0, 1, 4, 5 (in prev.: 3, 2, 7, 6); and edges: 0, 4, 8, 9 (in prev.: 2, 6, 10, 11).

template<class D , class V >
void Rgl::Mc::TMeshBuilder< D, V >::BuildCol ( UInt_t  depth,
const SliceType_t prevSlice,
SliceType_t slice 
) const
private

nz == depth, nx == 0, ny : [1, H - 1].

Two neighbours - from previous slice ("bottom" cube) and previous cube in a column.

Definition at line 623 of file TGLMarchingCubes.cxx.

◆ BuildFirstCube() [1/2]

template<class D , class V >
void Rgl::Mc::TMeshBuilder< D, V >::BuildFirstCube ( SliceType_t slice) const
private

The first cube in a grid. nx == 0, ny == 0, nz ==0.

Definition at line 238 of file TGLMarchingCubes.cxx.

◆ BuildFirstCube() [2/2]

template<class D , class V >
void Rgl::Mc::TMeshBuilder< D, V >::BuildFirstCube ( UInt_t  depth,
const SliceType_t prevSlice,
SliceType_t slice 
) const
private

The first cube in a slice with nz == depth.

Neighbour is the first cube in the previous slice. Four values and four edges come from the previous cube.

Definition at line 480 of file TGLMarchingCubes.cxx.

◆ BuildMesh()

template<class D, class V>
void Rgl::Mc::TMeshBuilder< D, V >::BuildMesh ( const D *  src,
const TGridGeometry< V > &  geom,
MeshType_t mesh,
iso 
)

Build iso-mesh using marching cubes.

Definition at line 177 of file TGLMarchingCubes.cxx.

◆ BuildNormals()

template<class D , class V >
void Rgl::Mc::TMeshBuilder< D, V >::BuildNormals ( ) const
private

Build averaged normals using vertices and trinagles.

Definition at line 772 of file TGLMarchingCubes.cxx.

◆ BuildRow() [1/2]

template<class D , class V >
void Rgl::Mc::TMeshBuilder< D, V >::BuildRow ( SliceType_t s) const
private

The first row (along x) in the first slice: ny == 0, nz == 0, nx : [1, W - 1].

Each cube has previous cube. Values 0, 3, 4, 7 are taken from the previous cube. Edges 3, 7, 8, 11 are taken from the previous cube.

◆ BuildRow() [2/2]

template<class D , class V >
void Rgl::Mc::TMeshBuilder< D, V >::BuildRow ( UInt_t  depth,
const SliceType_t prevSlice,
SliceType_t slice 
) const
private

Row with ny == 0 and nz == depth, nx : [1, W - 1].

Two neighbours: one from previous slice (called bottom cube here), the second is the previous cube in a row.

Definition at line 546 of file TGLMarchingCubes.cxx.

◆ BuildSlice() [1/2]

template<class D , class V >
void Rgl::Mc::TMeshBuilder< D, V >::BuildSlice ( SliceType_t s) const
private

Slice with nz == 0.

nx : [1, W - 1], ny : [1, H - 1]. nx increased inside inner loop, ny - enclosing loop. Each cube has two neighbours: ny - 1 => "left", nx - 1 => "right".

◆ BuildSlice() [2/2]

template<class D , class V >
void Rgl::Mc::TMeshBuilder< D, V >::BuildSlice ( UInt_t  depth,
const SliceType_t prevSlice,
SliceType_t slice 
) const
private

nz == depth, nx : [1, W - 1], ny : [1, H - 1].

Each cube has 3 neighbours, "bottom" cube from the previous slice, "left" and "right" from the current slice.

Definition at line 697 of file TGLMarchingCubes.cxx.

◆ NextStep()

template<class D , class V >
void Rgl::Mc::TMeshBuilder< D, V >::NextStep ( UInt_t  depth,
const SliceType_t prevSlice,
SliceType_t curr
