Abstract:
A method for rendering an object, the method comprising the steps of: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 said object with a soft crease that has an appearance based on said selected value, the step of rendering including determining a vertex that is created in the middle of an edge, E, based on the equation, P(E)=Â¼*[(E.v0+E.v1)*((1+c)+(P(E.F0)+P(E.F1))*(1âˆ’c)]; wherein said soft crease represents an interpolation between a hard crease and a smooth surface; wherein the closer said selected value is to said first value, the more the appearance of said soft crease resembles said hard crease; and wherein the closer said selected value is to said second value, the more the appearance of said soft crease resembles said smooth surface.
