Image based reconstruction from multiple views is an interesting challenge. Recently methods of optimisation based voxel colouring have appeared, which make use of incremental visibility updates. We present an alternative incremental voxel colouring algorithm in the mould of GVC-LDI  which directly associates each visible voxel with the set of rays in it’s visible projection, using ray-voxel traversal as a mechanism for updates. e make some time comparisons using calibrated photographs and synthetic images, as well looking at optimisation based voxel colouring and level of detail. Results show that our method compares favourably to GVC-LDI.
