Characterization and Generation of 3D Realistic Geological Particles with Metaball Descriptor based on X-Ray Computed Tomography

Understand

The morphology of geological particles is crucial in determining its granular characteristics and assembly responses.

• In this paper, Metaball-function based solutions are proposed for morphological characterization and generation of three-dimensional realistic particles according to the X-ray Computed Tomography (XRCT) images.
• For characterization, we develop a geometric-based Metaball-Imaging algorithm.
• This algorithm can capture the main contour of parental particles with a series of non-overlapping spheres and refine surface-texture details through gradient search.
