Key Points

To develop an efficient computational scheme using quantitative invisibility for resolving line visibility and hidden-line removal in machine-rendered 3D solids.
Modeled geometric shapes using surface contour curves and intersection curves.
Formulated a visibility determination algorithm to identify and categorize occluded line segments from an observer's perspective.
Enabled comparatively high-speed computation of line visibility for complex solid geometry.
Achieved high graphical resolution without visual ambiguity caused by hidden lines.
