Anotace: The paper deals with the problematics of data hiding into domain specific hierarchical data structures which are dedicated to the geometry of the voxelized three-dimensional scenes representation. Sparse Voxel Directed Acyclic Graph (SVDAG) as the suitable representant of this category of data structures was chosen. Possibility of data hiding into this structure, based on the knowledge of its construction on binary level was investigated and several data hiding methods were described and leveraged as the contribution of this paper.
