Detailed Description

template<typename TImageType, typename TFunctor, typename Space, typename KSpace>
struct DGtal::AddTextureImage3DWithFunctor< TImageType, TFunctor, Space, KSpace >

class to insert a custom 3D textured image by using a conversion functor and allows to change the default mode (GrayScale mode) to color mode.

Template Parameters

TImageType	the type of the used as texture (should follow the concept of CConstImage).
TFunctor	the functor type to transform source image scalar value into the one of the image being displayed.

A typical use can be illustrated by displaying a grayscale source image with artificial color defined from a colormap (see viewer3D-8-2DSliceImages.cpp viewer3D-9-3Dimages.cpp): We can first add a functor to convert grayscale value into RGB int:

#include "DGtal/io/DrawWithDisplay3DModifier.h"
#include "DGtal/io/viewers/DrawWithViewer3DModifier.h"
#include "DGtal/io/colormaps/HueShadeColorMap.h"
#include "DGtal/io/Color.h"

struct hueFct{
 inline
 unsigned int operator() (unsigned char aVal) const
  {
    HueShadeColorMap<unsigned char>  hueShade(0,255);
    Color col = hueShade((unsigned char)aVal);
    return  (((unsigned int) col.red()) <<  16)| (((unsigned int) col.green()) << 8)|((unsigned int) col.blue());
  }
};

Then you can define and add the object AddTextureImage2DWithFunctor in a viewer:

  viewer << AddTextureImage3DWithFunctor<Image3D, hueFct, Z3i::Space, Z3i::KSpace> (imageCrop2, hueFct(), MyViewer::RGBMode);
  viewer << MyViewer::updateDisplay;

Note

If you change the image date don't forget to specify again the functor with the UpdateImageData object.
