Abstract:

The marching cubes algorithm is the most influential isosurface construction algorithm. In this paper, a moving pixelvoxel surface rendering algorithm is proposed. According to the marching cubes algorithm, the display properties of object surface and voxel characteristics, we render the object isosurface with boundary voxel and reconstruct the 3D surface. In the experiments, reconstruct the bone tissue with the proposed algorithm and the Matlab rendering function. Finally, by comparing two experimental results, we show that this algorithm can reconstruct an object 3D surface and avoid ambiguity. But the reconstructed 3D surface is not smooth and the reconstructed time is long.
