摘要 It is critical to identify core/cavity and undercut surfaces of molds in parting line generation. A new Ray-Testing approach is presented to detect these surfaces by identifying the visibility of surfaces. A simple, direct and efficient algorithm to identify surface visibility is developed. Case studies show that the approach is practical and valuable in automated parting line generation. It is critical to identify core/cavity and undercut surfaces of molds in parting line generation.
