Abstract:
A method for producing a computer-assisted animated film, comprising the steps of:generating a 3-D model of an object;selecting a first view of said object;applying 2-D brush strokes to said first view;generating 2-D stroke points by sampling tracks of 2-D brush strokes applied to said view of said object;determining a 2-D stroke width and width direction at each of said 2-D stroke points;translating said 2-D stroke points into 3-D stroke points;translating said 2-D stroke widths and width directions into a 3-D stroke width and width direction at each of said 3-D stroke points; applying color to said object according to said 3-D stroke width and width direction at each of said 3-D stroke points;selecting a second view of said object that reveal surfaces that were occluded in said first view;applying additional 2-D brush strokes to said second view;generating additional 2-D stroke points by sampling tracks of said additional 2-D brush strokes applied to said second view of said object;determining a 2-D stroke width and width direction at each of said additional 2-D stroke points;translating said additional 2-D stroke points into 3-D stroke points;translating said 2-D stroke widths and width directions into a 3-D stroke width and width direction at each of said 3-D stroke points; andapplying color to said object according to said 3-D stroke width and width direction at each of said 3-D stroke points.
