摘要： In this article an algorithm for creating 3D Koch curves is proposed. Based on this algorithm, a 3D visualisation of soil pores is constructed. Firstly according to the minimal value principle of generalised energy, we computed the turning point coordinates of the Koch curve and extended it into a 3D curve, and analysed the soil pore structure and the aperture's statistical characteristics; then we modelled the quantificational control of the aperture's variety and distribution and transferred the agriculture parameters of the soil into system parameters. The technique of layer rendering was used to boost the realism of visualisation. Comparing the virtual pictures generated with the metrical data and using the method of qualitative and quantificational contrastive analysis, our approach can generate soil pore 3D structures more realistically and better representing the soil features.
