Helmet

This model is used as a learning case to understand surface modeling in creating complex curved geometry. The helmet shape is built from reference curves, which are then developed into surfaces using features such as loft and boundary surface. The main focus of this exercise is achieving smooth transitions between surfaces (continuity), especially around the dome and visor area. Trimming and knitting processes are applied to form a clean and unified geometry. The visor is modeled separately to demonstrate multi-body surface modeling and alignment with the main shell. Rendering is used to evaluate surface quality and improve visualization. This exercise helps in understanding surface continuity, precision in modeling, and the integration between technical design and visual appearance.
