Conventional splines offer powerful means for modeling surfaces and volumes in three-dimensional Euclidean space. A one-dimensional quaternion spline has been applied for animation purpose. where the splines are defined to model a one-dimensional submanifold in the three-dimensional Lie group. Given two surfaces. https://www.roneverhart.com/Almanac-Sunshine-Opportunity-Barrel-Aged-Hibiscus-Sour-single/
