Ray casting for incremental voxel colouring (2005)

Image based volumetric reconstruction from multiple views is an interesting challenge. Recently several methods of optimisation–based voxel colouring have appeared, which make use of incremental visibility. Culbertson et al. presented a way of determining visibility incrementally by using layered depth images as a data structure (GVC-LDI). We present an alternative algorithm which provides the same outputs. We use ray casting which is simpler and more efficient than using layered depth images. We make some simple comparisons using rasterized images and look at how it can be applied to optimisation based carving as well as level of detail.
