Abstract
Light field provides an alternative to describing objects by geometric models. It has the advantage of geometric models, namely new views of an object can be generated at run time. The time required to generate a new view is independent of the scene complexity. It lacks, however, the flexibility of geometric models to compose complex scenes. This thesis proposes a method of merging multiple light field objects into a more complex light field. An approximate volume is first reconstructed from the light field. The level of detail can be controlled in the reconstruction process. A test ray is sent into the scene to determine visibility based on the extracted volume. In the merging process, affine and other transformations can be applied to individual objects. The method computes visibility correctly when there is sufficient level of detail in the volume. This thesis shows that light fields can be composed and transformed to increase its usefulness.@MastersThesis{Chiu1998,
