How close are we to practical systems for effective 3d visualisation? Blundell provides both a good historical survey of earlier attempts, and a synopsis of current work. The earlier methods do seem primitive.

Naturally, the bulk of the text focuses on what is currently attempted. A wide range of hardware ideas. Like a swept volume. Akin perhaps to rasterising on a traditional TV screen. But now the intent is to generate voxels instead of pixels. There are drawbacks, like a visual dead zone.

Another method uses a static volume. Where light emitters are embedded in this volume. And excited to generate a "true" 3d image. One problem is the sheer mass of computational support, if one wants a 3d time varying display. This bandwidth bedevils most implementations. And static volumes also come with dead zones.

Yet another approach uses a planar screen with fixed beams. But this gives rise to various distortions.

Overall, a good description of how things stand. The technology still needs improvement.
