• Sliding Window
  

  A sliding window represents a movable view/slice of a larger dataset/field, to make accessing data-elements both faster and more convenient; they can be implemented in several ways...

• Raytracing
  

  Rendering images via raycasting, be it on the CPU or GPU, is a powerful method, especially when it comes to voxels.

• 3D Raycasting
  

  The Digital Differential Analyzer (DDA) algorithm, adapted to 3D, is exactly the thing one needs to travel along a line (or a ray) through a grid of voxels.
