Abstract

Embodiments of the present disclosure are directed to methods and computer systems for converting datasets into three-dimensional (“3D”) mesh surface visualization, displaying the mesh surface on a computer display, comparing two three-dimensional mesh surface structures by blending two primary different primary colors to create a secondary color, and computing the distance between two three-dimensional mesh surface structures converted from two closely-matched datasets. For qualitative analysis, the system includes a three-dimensional structure comparison control engine that is configured to convert dataset with three-dimensional structure into three-dimensional surfaces with mesh surface visualization. The control engine is also configured to assign color and translucency value to the three-dimensional surface for the user to do qualitative comparison analysis. For quantitative analysis, the control engine is configured to compute the distance field between two closely-matched datasets.

converting, by the processor, the plurality of images into a plurality of 3D mesh surfaces graphically representing the object at the plurality of points in time responsive to the plurality of first user selections;
presenting, by the processor, the plurality of 3D mesh surfaces on a user interface responsive to the plurality of first user selections;
determining, by the processor, a distance differential value associated with each vertex within the plurality of 3D mesh surfaces;
receiving, by the processor, a plurality of second user selections of the plurality of 3D mesh surfaces;
assigning, by the processor, a plurality of primary colors and a plurality of translucencies to the plurality of 3D mesh surfaces responsive to the plurality of second user selections, wherein each vertex is assigned one of the plurality of primary colors in accordance with its distance differential value, and wherein the plurality of primary colors are visually distinct from each other;
