When rendering a patch mesh in Renderman with wrapping in the u-direction, and with each u-row of points co-planar, one obtains a sort of cylindrical tube. (These are commonly called objects of extrusion or duct objects) Suppose I wish to add endcaps to the object. Is there a nice way to accomplish this in Renderman? When adding, say, the top cap, one can make an nu X 2 patch mesh with the first u-row being the top u-row in the original mesh, and the second u-row all being the same point, a point enclosed within the top u-row of points. This will only work, however, if the top u-row of points, when connected in succession, form a concave polygon. Can anyone offer a solution if the top u-row points form a convex polygon?
