Definitions

  • the virtual object is represented as a volumetric representation.
  • a portion of the volumetric model is converted into an alternative representation.
  • the alternative representation can be a representation having a different number of dimensions from the volumetric representations.
  • a stimulus is applied to the alternative representation by employing a force-feedback haptic interface.
  • the response of the alternative representation to the stimulus is calcu lated.
  • the change in shape of the virtual object is determined from the response of the alternative representation.
  • JP6231 22 1 to SETO MIKI NAGASHIMA YOSHIO introduced a three- dimensional object shape generating method. The purpose was to provide a function for working and generating directly a three-dimensional object shape based on the motion and the sense of hand.
  • a pressure sensitive sensor sheet is stuck onto the surface of a fundamental structu re, pressu re applied to its su rface is detected by user's hand and a point affected by its pressure is measured by a measuring data processing. From pressure data in those points of application, a pressure distribution histogram is generated by a plotting processing in threshold difference arithmetic, and to an object by a graphics expression of its fundamental structure, working and deformation are applied in the same way as clay works are executed.
  • a formative image is expressed on a display in an immediately visible shape through a graphics data generating part and a graphic engine.
  • the shape processing is performed by moving and changing polygon's position. By moving the control points in open space (x,y,z) or by changing the graphs comprising shapes, polygon's position is changed thus changing the shape's structure.
  • the controlling of the structu re may be performed by mouse movements directly on the object.
  • the method of the invention provides highly flexible creating and editing models in three-dimensional space.
  • the invention provides a method of creating and modifying an object or a portion of an object by using finger movements on touch screen as controlling tool similar to shape processing in real world and creating unlimited variety of gestu res. For example: rolling the fingers back and forth (kneading like) with the help of virtual surface resistance will turn a ball into an elongated sausage.
  • Stage I To slice a certain amount of material (for example, clay), from the main lump and drag it to a working area.
  • material for example, clay
  • Stage III In one embodiment of the invention - turning the ball into a cylinder-like shape, repetition of movements of the fingers up and down,
  • Stage IV In another embodiment of the invention, the ball itself is divided into more than one influence areas and different manipulations may be performed on each area separately.
  • Stage VI In another embodiment of the invention, exerting pressu re on the object while rolling it forward and backwards and exerting equal resistance from the surface, (on which the shape is virtually placed), thins its' shape. An equal change into 360° is performed by resistance of the lower surface and the rolling movement.
  • Stage VII - In another embodiment of the invention, same may be performed with any other shape, like pear, egg etc.
  • Stage VIII Once the desired shape is complete, the object is divided into more than one vertical influence areas, which react differently to pressing or rolling (back and forth). Pressing gradually crushes the shape and causes it to flatten; rolling causes the right or left areas to gradually turn into conelike shape.
  • FIG. 1 - Is a drawing that illustrates a ball in virtual space.
  • FIG. 3 - Is a drawing that illustrates the impact of exerting pressure on u pper part, while rolling back and forth. Object mass does not change.
  • Fig. 4 - Is a drawing from a different angle that illustrates the impact of exerting pressure on u pper part while rolling back and forth. Object mass does not change.
  • FIG. 5 - Is a drawing that illustrates the impact of circular movements.
  • FIG. 1 - The drawing illustrates a slice of material (for example, clay)
  • FIG. 30 Fig. 2 - The drawing illustrates exerting pressure on material against a surface. Exerting pressure on the ball in modeling stage causes its deformation on one side or symmetrically on top and bottom parts.
  • FIG. 3 The drawing illustrates the impact of rolling - finger movements forward and backwards and circular movement performed while rolling, simulating realistic three-dimensional behavior. Object mass does not change.
  • FIG. 4 The drawing illustrates the finger and its opposing pressure and the impact of circular movements performed when rolling. For example, a cylinder, simulating realistic three-dimensional behavior. Object mass does not change.
  • FIG. 5 The drawing illustrates the finger and its opposing pressure and the impact of circular movements performed when rolling a ball.
