Title: High-speed image generation of complex solid objects using octree encoding
IPC: G06T15/40
Filed: 1985-01-09
Abstract: An image generator for generating two-dimensional images of three-dimensional solid objects at a high speed defines a scene to be displayed within a cuboid three-dimensional universe which has been hierarchically subdivided into a plurality of discrete volumes of uniform size and similar orientation. The three-dimensional universe is represented by a tree structure having a plurality of nodes, one for each volume in the three-dimensional universe which is at least partially occupied by objects in the scene. A user may select a point of view for viewing the object. Nodes in the tree structure representing the three-dimensional universe are visited in a sequence determined by the point of view selected by the user so that nodes corresponding to volumes which are unobstructed by other volumes are visited first. Each visited node which is enclosed by the object is projected onto a subdivided view plane organized into a hierarchy of a plurality of discrete areas. Areas of the view plane which are completely enclosed by the projection are painted onto a display screen. Areas which intersect but are not enclosed by the projection are further subdivided to locate those areas which are enclosed. A representation of the hierarchically-subdivided view plane arranged in a tree structure is stored in a store. Each time an area of the view plane is painted, an entry in the representation of the view plane corresponding to that area is marked. The corresponding entry in the representation of the view plane is checked before an area is painted, to ensure that no area is painted more than once so that hidden surfaces are not displayed. To create sectional views, a user may define a region of the three-dimensional universe, and volumes outside of that region are not projected. Due to the hierarchical structure of the three-dimensional universe and the two-dimensional view plane, the symmetry of subdivisions, and the resulting simplicity of the calculations necessary to create an image, real time image generation wherein calculations necessary to create the image are performed by hard-wired digital logic elements to increase speed performance is possible.

Abstract: A process for the preparation of paper suitable for use as 
cover sheets for the production of gypsum wallboard which 
comprises forming a suitable aqueous slurry of paper pulp, 
passing the slurry through papermaking apparatus wherein suc­
cessively are added a neutral size material and a retention aid, 
and wherein the slurry is additionnally passed through a machine 
chest, a plurality of fan pumps, apparatus for forming the paper 
and subsequently drying the paper, the improvement which 
comprises the step of introducing a high molecular weight low 
cationic charge density retention aid polymer into the slurry 
immediately at the discharge situs of the fan pumps, whereby 
contaminants present in the slurry are retained and are not 
deposited on the surfaces of the papermaking apparatus. In a 
improved embodiment, a small amount of the high molecular 
weight low charge density polymer is utilized to replace cationic 
starch to act as a retention aid for the neutral size material, and a 
low molecular weight high charge density polymer is introduced 
into the machine chest as a coagulant to further promote the 
retention of contaminants present in the slurry to avoid their being 
deposited on the surfaces of the paper-making machine.

Patent EP-0280968-A3 (EP)
Title: Shaping geometric objects by cumulative translational sweeps
IPC: G06F17/50
Filed: 1988-02-19
Abstract: Cumulative translational sweeps are used to shape geometric objects in a computer model, 
and they permit display of the resulting changes in shape in the object modelled, and con­
trol of processes involving the object modelled. If the geometric object is polyhedral, the 
cumulative translational sweeps, by creating additional facets, effect selective rounding 
along model edges and around model vertices. This permits computer modelling of the 
growth of layers, encompassing in addition to flat surface growth, growth with rounding 
around corners and over obstacles. Such growth occurs in the manufacture of semicon­
ductors. Modelling a change in a solid structure in stages of growth (path 5) (or shrinking) (path 6) and 
of rounding, as might take place during processing of integrated circuits is achieved by 
controlled sweep sequences that sweep the structure a finite number of times in accord­
ance with a rayset and stipulated parameters of shape, balance, convexity/concavity, de­
gree of faceting, and memory limitation. The cumulative translational sweep (CTS) is 
applied in combination with Boolean operations to simulate growth and shrinking over 
the boundary regions of polyhedral models. By creating additional facets, it effects 
stipulated selective or global rounding effects along model edges and around model 
vertices. Such sweeps are examined in terms of Minkowski sums -- of the geometric objects 
that are swept, with structuring geometric shapes that are convex polyhedron from the 
zonotope subclass of the mathematical family of objects known as polytopes.
