This paper presents a new approach for the voxelization of volumetric scene graphs. The algorithm generates slices of each primitive intended to be voxelized using an FPGA based pixel processor. The Blist representation is used for the volume scene tree which reduces storage requirement for each voxel to the log(H + 1) bits. The most important advantage of this voxelization algorithm is that any volume scene tree expression can be evaluated without using any computation or stack. Also the algorithm is not object specific, i.e. the same algorithm can be used for the voxelization of different types of objects (convex and concave objects, polygons, lines and surfaces).
