Abstract
A representation of a surface of one or more objects is positioned in a virtual space is obtained in a computer animation system. Thereafter, a guide curve specification of a guide curve in the virtual space relative to the surface is received. Thereafter, the computer animation system computes a first set of tangent vector values for differentiable locations along the guide curve and computes a second set of tangent vector values for nondifferentiable locations along the guide curve. Using the first set and second set, the computer animation system computes a third set of tangent vector values for locations on the surface other than locations along the guide curve and computes a tangent vector field over the surface from at least the first set of tangent vector values, the second set of tangent vector values, and the third set of tangent vector values.
