文摘

•: A new method of shape diameter function computation based on depth peeling.
•: Comparison of the depth peeling method with parallel raycasting using OpenCL.
•: Spherical Fibonacci sampling for sampling of cone during raycasting.
•: Smoothing of SDF values using texture-space diffusion and STM parameterization.
•: Proposed applications in skeleton extraction – skeleton sheets, modification of iteration parameters during Laplacian-based skeleton extraction and fast liner skeleton extraction.
