                         demand high exhibition frame rates of large scale terrain models. 
                         Placing tridimensional objects within a voxel based world may be 
                         an ease task for elementary objects. Complex objects are better 
                         represented by polygonal meshes. Integrating a voxel based terrain 
                         model with polygonal camera model brings together the benefits of 
                         both models. Such integration should be done with the aid of a 
                         z-buffer. In this paper we propose a solution to the problem of 
                         calculating the z-coordinate of each painted pixel in a voxel 
                         based terrain model. The proposed solution exploits the coherence 
                         of the pixels in the same column and uses a linear cost increment 
                         to update the z-coordinate. The proposed solution considers the 
                         situation when the view plane is not vertical.",
