Flower CT Volume Library

updated 2014/8/6

added 3D object viewer, 2016/2/23

You can use these CT volumes and surface models for academic purposes (researches, educations, etc) freely by referring the following paper:

Takashi Ijiri, Shin Yoshizawa, Hideo Yokota, Takeo Igarashi. 2014. Flower Modeling via X-ray Computed Tomography, to appear at SIGGRAPH 2014.

Please DO NOT use the rendering results of our Blender file AS IT IS in your official article, since they are on our paper. (Slightly modifying the camera position or parameters seems to be enough for reuse)

To load/convert our raw volume data (.traw3D_ss)

You can load, check, and convert flower CT volumes (.traw3D_ss) by using SimpleVolumeViewer (with MFC/C++ code).

*.traw3D_ss file is our 3D volume data format that contains i) voxel resolution, ii) voxel pitch, and iii) volume data (signed short array). It can be loaded by C++ as follows;

 
    FILE *fp = fopen( "*.traw3D_ss", "rb" );
    if( fp == 0 ) return false;

    int    W , H, D; // resoulution (Width, Height, Depth)
    fread( &W , sizeof(int   ), 1, fp ); 
    fread( &H , sizeof(int   ), 1, fp ); 
    fread( &D , sizeof(int   ), 1, fp );

    double px,py,pz; // pitch in x,y,z axes
    fread( &px, sizeof(double), 1, fp ); 
    fread( &py, sizeof(double), 1, fp ); 
    fread( &pz, sizeof(double), 1, fp );

    //read signed short array
    short *volume = new short[ W*H*D ];
    if( fread( volume, sizeof(short), W*H*D, fp ) != W*H*D ) { fclose( fp ); return false;}

    fclose(fp);

The 3D object viewer was implemented with a support from Hidetomo Kataoka, an undergraduate student, at Ritsumeikan University.

We will upload more CT volumes which is not used in the paper.
