Based on blending surface method by combination functions,a new algorithm of designing G1 continuous curve on the base surface was proposed.Given an arbitrary sequence of points and the tangent directions of the points,a space curve can be designed.By using the normal projection method,the curve was projected orthogonally onto the base surface and thus the blending contact curve was obtained.In this way,the contact curve can be placed at the appropriate position according to the design requirements as the b...
