摘要： A method and apparatus for painting in a computer controlled video display system is described. A current shape of a brush stroke is determined. A current direction of the brush stroke is determined. A current position is determined. A current color is set equal to a color at the current position. The step of drawing the brush image on the display comprises the steps of setting a color of the brush image equal to the current color, setting a position of the brush image equal to the current position, and setting a direction of the brush image equal to the current direction of the brush stroke.

摘要： A free form source model is divided into surface sections by identifying external boundary edges and internal boundary edges. The boundaries are connected or further divided as necessary to achieve a perimeter about each surface section which is a single closed curve. Doubly curved surfaces may also be subdivided. A developable output surface which approximates each source model surface section is then determined by calculating the minimum cost triangulation of each source model perimeter. Costs to be minimized may include the deviation of the triangle surface normal from the edge normal, the degree of bending between adjacent triangles, or the departure of the approximated surface from the original surface. The two-dimensional boundary of the flattened surface guides fabrication of output segments from sheet material, which may be assembled into an output object comprised entirely of developable surfaces.
