Hello together. In order to get a serious understanding of G3 needs amongst surface modelers I want to ask you three questions:
1. How do you/your customers measure G3? I am aware about the smoothness of curvature combs. If there is another method, please answer. I am specifically interested in tolerances and how those tolerances will be calculated.
2. In order to achieve G3 mathematically there must be added a fourth CV row. If this is the case then I would like to know if it won’t hurt you. A smooth curvature plot across two surfaces can be reach even with the proper scaling of the first three CV rows.
3. In which tools do you see G3 surface continuity?
I know this topic is somehow controversial. I need solid and serious answers on those three questions in order to use it for designing our software. I appreciate your input in advance.
