Abstract: Various methods are provided for organizing multiple geometric parts forming an object in 3D voxel data and/or for permitting a user to detach and/or reattach these parts. In one embodiment, the 3D voxel data are organized in two steps. First, a part voxel set is created for each geometric part. Second, a master XZ table is created, which defines geometric locations within multiple part voxel sets based on references. A method allows a user to detach and/or reattach parts in five steps: (a) receiving a user request to detach a first geometric part; (b) retrieving a first part voxel set defining the first geometric part; (c) rendering the first geometric part; (d) updating the master XZ table by replacing references to the first part voxel set with new references; and (e) rendering the rest of the object based on the updated master XZ table.

Abstract: An air mattress includes a top and a bottom wall connected by a plurality of longitudinally-extending, laterally-spaced vertical partitions which divide the mattress into a plurality of longitudinal air compartments. The side edges of each partition are secured to the top and bottom walls by means of a heat sealed joint.

Abstract: The present invention relates to film base material. A film of synthetic linear polyester has superimposed thereon a phenoxy resin of the formula ##SPC1##Wherein each of R.sub.1 to R.sub.7 is a hydrogen atom or a lower alkyl or cyclohexyl group, R.sub.8 is a hydrogen atom or an acyl radical of the formula ##EQU1## wherein m is 0 to 6, at least one of X, Y and Z is a chlorine or bromine atom or a cyano group, the other of X, Y and Z are each hydrogen atoms or bromine or chlorine atoms, n is at least 50 and from 50 to 100 % of the R.sub.8 groups are a said acyl residue. An improved adhesion between the film base material of this composition and a hydrophilic layer coated thereon is achieved.
