No modification should be necessary for the existing code.
most relevant changes:
creation of folder:
vcg/connectors
vcg/connectors/hedge.h
vcg/connectors/hedge_component.h
addition to the container of half edges to the trimesh:
HEdgeContainer hedge; // container
int hn; // number of half edges
addition of
vcg/trimesh/update/halfedge_indexed.h
which contains:
- the functions to compute the half edge representation from the indexed and vivecersa
- the functions to add or remove an half edge
Note: No changes to existing code need be the done, this mod
should be fully backward compatible
Old way to define a TriMesh ==============
struct MyMesh: public vcg::tri::TriMesh< vector<MyVertex> , vector <MyFace> >{};
new ways to define a TriMesh ==============
struct MyMesh: public vcg::tri::TriMesh< CONT1 >{};
struct MyMesh: public vcg::tri::TriMesh< CONT1 , CONT2>{};
struct MyMesh: public vcg::tri::TriMesh< CONT1 , CONT2, CONT3>{};
where CONT[i] can be vector< [MyVertex | MyEdge | MyFace ] >
(the order is unimportant)
Note for the developers: the change to make to existing projects is very little
but strictly necessary to compile. This change IS NOT backward compliant.
==== OLD ==== way to define a TriMesh:
// forward declarations
class MyVertex;
class MyEdge;
class MyFace;
class MyVertex: public VertexSimp2 < MyVertex, MyEdge, MyFace, vertex::Coord3f,...other components>{};
class MyFace: public FaceSimp2 < MyVertex, MyEdge, MyFace, face::VertexRef,...other components>{};
class MyMesh: public TriMesh<vector<MyVertex>,vector<MyFace> >{};
==== NEW ==== way to define a TriMesh:
// forward declarations
class MyVertex;
class MyEdge;
class MyFace;
// declaration of which types is used as VertexType, which type is used as FaceType and so on...
class MyUsedTypes: public vcg::UsedType < vcg::Use<MyVertex>::AsVertexType,
vcg::Use<MyFace>::AsFaceType>{};
class MyVertex: public Vertex < MyUsedTypes, vertex::Coord3f,...other components>{};
class MyFace: public Face < MyUsedTypes, face::VertexRef,...other components>{};
class MyMesh: public TriMesh<vector<MyVertex>,vector<MyFace> >{};
===== classes introduced
[vcg::UsedType] : it is a class containing all the types that must be passed to the definition of Vertex, Face, Edge... This
class replaces the list of typenames to pass as first templates and the need to specify the maximal simplicial. So
<MyVertex, MyEdge, MyFace becomes <MyUsedTypes<
and
VertexSimp2 becomes Vertex
[vcg::Use] : an auxiliary class to give a simple way to specify the role of a type
Note 2: the order of templates parameters to vcg::UsedTypes is unimportant, e.g:
class MyUsedTypes: public vcg::UsedType <vcg::Use<MyVertex>::AsVertexType,
vcg::Use<MyEdge>::AsEdgeType,
vcg::Use<MyFace>::AsFaceType>{};
is the same as:
class MyUsedTypes: public vcg::UsedType <vcg::Use<MyFace>::AsFaceType,
vcg::Use<MyEdge>::AsEdgeType,
vcg::Use<MyVertex>::AsVertexType>{};
Note 3: you only need to specify the type you use. If you do not have edges you do not need
to include vcg::Use<MyEdge>::AsEdgeType in the template list of UsedTypes.
==== the Part II will be a tiny change to the class TriMesh it self.
added to IsValidHandle the check that pointer to data is not null.
Explanation:
a handle may be not valid for two reasons:
1) the attribute has been destroyed with a DeletePer*Attribute
2) the handle has been declared but not initialized.
The change is to cover the case 2)
The member 'camera' of the base trimesh class, is no more used since Dec 2006.His initial purpose was keeping intrinsics of the camera, but it is a long time that intrinsics have moved into the Shot class.
The I/O procedure already comply this fact filling only the interal structure.
This modification removes the old way to define simplexes (already deprecated and unsupported).
In the following SIMPLEX = [vertex|edge|face|tetrahedron]
All the stuff that was in vcg/simplex/SIMPLEXplus/ has now been promoted to vcg/simplex/
Details:
- the folder vcg/simplex/SIMPLEX/with has been removed
- the file vcg/simplex/SIMPLEX/base.h has been renamed into vcg/simplex/SIMPLEX/base_old.h
- the content of vcg/simplex/SIMPLEXplus/ has been moved into vcg/simplex/SIMPLEX/
- the folder vcg/simplex/SIMPLEXplus/ has been removed
Actions the update the code using vcglib:
replace <vcg/simplex/SIMPLEXplus/*> with <vcg/simplex/SIMPLEX/*> in every include
for MESHLAB users: already done along with this commit
Added default template to TriMesh to include the edges.
Added peredge attributes.
These modification do not require any change to the code using TriMesh, but it allows
to specify a real type of edge in case you want to use it.
Added components to the face to handle generic polygons.
(compiled with .net and gcc)
This commit includes the following files:
vcg/complex/trimesh/base.h
Added deallocation of polygon data in the destructor
vcg/complex/trimesh/allocate.h
generalization from 3 to VN() vertices
vcg/complex/trimesh/update/topology.h
generalization from 3 to VN() vertices
vcg/complex/trimesh/update/flags.h
generalization from 3 to VN() vertices
vcg/simplex/face/pos.h
generalization from 3 to VN() vertices
vcg/simplex/faceplus/base.h
Added the method VN() to query the number of vertices
of the polygon (deafult 3) and methods Prev and Next
vcg/simplex/faceplus/component.h
added Alloc and Dealloc calls along the hierarchies
