Summary:Techniques for rendering 3-D medical data are described. They
consist of (1) surface-based techniques, which apply a surface detector
to the sample array, then fit geometric primitives to the detected
surfaces, and finally render the resulting geometric representation; (2)
binary voxel techniques, which begin by thresholding the volume data to
produce a three-dimensional binary array; the cuberille algorithm then
renders this array by treating 1's as opaque cubes having six polygonal
faces; and (3) volume-rendering techniques, a variant of the binary
voxel techniques in which a color and a partial opacity are assigned to
each voxel; images are formed from the resulting colored,
semitransparent volume by blending together voxels projecting to the
same pixel on the picture plane. Specialized display devices (stereo
viewers, varifocal mirrors, cine sequences, real-time image-generation
systems, and head-mounted displays) are described. Topics for future
research are identified
