How does x-ray rendering work?

X-ray rendering is accomplished by measuring the intensity value of every voxel in the visible scene. The intensity of the x-ray rendering is determined by four factors:

  • The number of hit voxels between the eye and the ray going through that pixel – the higher the number of hits, the brighter the intensity.
  • The weight of the about intensity contribution is equal if there is no density attribute; otherwise the density attribute (at that voxel) determines the weight of the intensity contribution.
  • The angle of the hit with respect to the voxel’s normal, so you can get more of an edge effect.
  • The results of the intensity are normalized within the standard 0-1 intensity range.
