1. A computer-implemented method for creating three-dimensional (3D) variable resolution (VR) region geometries of a modeled object for use in a computer-implemented numerical simulation involving the modeled object, the computer-implemented method comprising:
generating two-dimensional (2D) orthographic views of a 3D modeled object that represents a visual real world appearance of the 3D modeled object;
identifying outer edges of each of the 2D orthographic views with a computer-based ray casting method to produce an outline of the outer edges for each respective one of the 2D orthographic views, wherein each one of the outlines is configured such that, if the outline were superimposed and aligned with the corresponding orthographic view, the outline would substantially align with the outer edges of the corresponding orthographic view, with no portion of the modeled object or any other modeled object extending substantially beyond the outline, wherein the computer-based ray casting method comprises, for each respective one of the 2D orthographic views:
casting virtual rays from different directions toward the 2D orthographic view within a plane of the 2D orthographic view; and
detecting an intersection point for each of the virtual rays with an edge of the 2D orthographic view.
