Simple soft creases for subdivision surfaces

摘要

Techniques are provided for creating soft creases for subdivision surfaces. Specifically, techniques are provided for creating an interpolation between a hard crease and a smooth surface. For example, the following steps may be performed to render an object with a soft crease: receiving, in response to user input, a selected value that falls within a range bounded by a first value and a second value; and rendering the object with a soft crease that has an appearance based on the selected value. The soft crease represents an interpolation between a hard crease and a smooth surface. The closer the selected value is to the first value, the more the appearance of the soft crease resembles the hard crease and, conversely, the closer the selected value is to the second value, the more the appearance of the soft crease resembles the smooth surface.
