Volume Acquisition


Volume data may be acquired in several ways, the most common of which are listed below.

Scanned volumes:
Some scanning technologies, such as Computerized Tomography (CT) or Magnetic Resonance Imaging (MRI) generate volume data. Figures 5a and 5c show CT scans of a human and an orangutan head, respectively.
Scan converted geometric models:
A geometric model can be voxelized [10], preferably with antialiasing [20], generating a volume-based representation of the model. Figures 6a, 6b, 7a, and 7b show examples of scan-converted volumes.
Interactive sculpting:
Interactive modeling, or sculpting [19] [7], can generate volume data directly.
Procedural definition:
Hypertexture volumes [15] can be defined procedurally by functions over 3D space.
