Detailed Description

template<typename Space = Z3i::Space, typename KSpace = Z3i::KSpace>
class DGtal::Board3D< Space, KSpace >

The class Board3D is a type of Display3D which export the figures in the format OBJ/MTL when calling the method saveOBJ.

The format OBJ/MTL is a geometry definition file format, this format has been adopted by many 3D graphics application vendors (pbrt, blender, etc.). to learn more about OBJ see http://en.wikipedia.org/wiki/Wavefront_.obj_file

When exporting Board3D regroup objects by they list name. If two lists have the same name they will melt in the same mesh eventually. If a list doesn't have a name the program will try to give it an unique name so it will become a separate mesh. Each list have a material description which correspond to its first element color. If two lists have the same name and merge the final mesh will have two materials (one per list).

Template Parameters

Space	a model of digital space (default type=Z3i::Space)
KSpace	a model of Khalimsky space (default type=Z3i::KSpace)

Examples: io/boards/dgtalBoard3D-1-points.cpp, io/boards/dgtalBoard3D-2-ks.cpp, io/boards/dgtalBoard3D-6-clipping.cpp, and shapes/exampleMeshVoxelizer.cpp.

Member Function Documentation

◆ className()

template<typename Space = Z3i::Space, typename KSpace = Z3i::KSpace>

std::string DGtal::Board3D< Space, KSpace >::className ( ) const

inline

Returns: the style name used for drawing this object.

Definition at line 109 of file Board3D.h.

    {
      return "Board3D";
    }

◆ getMaterialIndex()

template<typename Space = Z3i::Space, typename KSpace = Z3i::KSpace>

unsigned int DGtal::Board3D< Space, KSpace >::getMaterialIndex ( const DGtal::Color & aColor )

Check if the material associated woth the color exists. If it does, the method returns the material index. Otherwise, the new material is created.

Parameters

aColor a color

Returns: the material index associated with the color

◆ init()

template<typename Space = Z3i::Space, typename KSpace = Z3i::KSpace>

void DGtal::Board3D< Space, KSpace >::init ( )

protected

init function (should be in Constructor).

Referenced by DGtal::Board3D< Space, KSpace >::Board3D().

◆ isValid()

template<typename Space = Z3i::Space, typename KSpace = Z3i::KSpace>

bool DGtal::Board3D< Space, KSpace >::isValid ( ) const

Checks the validity/consistency of the object.

Returns: 'true' if the object is valid, 'false' otherwise.

template<typename TDrawableWithDisplay3D >

Board3D & DGtal::Board3D< Space, KSpace >::operator<< ( const TDrawableWithDisplay3D & object )

Draws the drawable [object] in this board. It should satisfy the concept CDrawableWithDisplay3D, which requires for instance a method setStyle( Board3D & ).

Parameters

object any drawable object.

Returns: a reference on 'this'.

◆ saveOBJ()

template<typename Space = Z3i::Space, typename KSpace = Z3i::KSpace>

void DGtal::Board3D< Space, KSpace >::saveOBJ	(	const std::string &	filename,

Save a OBJ image.

Parameters

filename	filename of the image to save.
isNormalized	if true, we use the bounding box to scale all objects such that they fit in [-1/2,1/2]^3 domain (default false),

Examples: io/boards/dgtalBoard3D-1-points.cpp, io/boards/dgtalBoard3D-2-ks.cpp, io/boards/dgtalBoard3D-6-clipping.cpp, and shapes/exampleMeshVoxelizer.cpp.
