Abstract: A method and apparatus for producing simulated oil paintings by means of a variety of commercial software programs. A digital color image is created and printed on to a substrate. Also printed on to the same substrate and registered thereto, is a slow drying, clear, embossing liquid in the pattern of brush strokes derived from one or more of the colors printed on to the substrate. A thermographic powder is dusted onto the embossing liquid while still wet and excess powder removed. The substrate is then heated to dry and raise the brush stroke pattern of the embossing ink to create a three dimensional effect on the substrate. The raised brush stroke pattern in combination with printed color image creates a work that has the three dimensional effect simulating an original oil painting.

Abstract: When the user touches a display screen, a touch-operated input device (7) detects a coordinate of a user-touched point on the display screen and a touch-input conversion program is executed to determine an axis, direction and speed of rotation of a three-dimensional object (40) on the basis of the user-defined coordinate, and give the information to a three-dimensional rendering program. The three-dimensional rendering program is executed to make a calculation for rotating the three-dimensional object (40) on the basis of the given information. The axis, direction and speed of the three-directional object rotation are repeatedly calculated in a fixed cycle only while the coordinate is kept defined by the user by continuously touching the display screen. Upon completion of each calculation, the results of calculation are given to the three-dimensional rendering program.

A previously selected filter for a preceding image can be considered when selecting a filter for a current image, enabling generation of 3-dimensional moving pictures.

Abstract: Any issues associated with manufacture of a part are identified and highlighted on a part model. A software method and system then uses motion of the part model for communicating the manufacturability issues to the customer. The motion can include a repositioning of a part rendering to a preferred orientation position, a fly-around so the customer can appreciate the next zoom location, and then a zooming in on the issue desired to be shown. Alternatively or in conjunction with the zooming and fly-around motion, the orientation of the part rendering showing the manufacturability issues can be three-dimensionally manipulated such as with a click-drag-drop command of the customer's computer mouse. By adding a moveable aspect to the communication, customers can much better understand which changes are recommended or required of the part.

Abstract: A posing system for three-dimensional characters and other models uses a stroke-based gestural language to position elements of the characters in a three-dimensional environment. A user draws a stroke in a two-dimensional interface in connection with a portion of model. The drawn stroke corresponds to an element of the model, such as a particular body part.

Additional elements are posed as necessary to further define the way in which the model as a whole should be posed. With a number of appropriate strokes for each of the elements, an animator can position the model in the scene.

Abstract: Where an arbitrary point on an image is designated in the field of a medical image, it is generally designated on a sectional image, and an arbitrary point on a three-dimensional image cannot be designated. According to the invention the orientation of the three-dimensional image is controlled in a first direction corresponding to the operation of the user. When an arbitrary point of the three-dimensional image is designated by the user, a plane passing through that point and normal to a display screen is created and stored. Next, the three-dimensional image is oriented in a second direction, and an arbitrary point is designated in the second direction by the user. Then, there is created a straight line which passes through that point and which is normal to the display screen. Then, the coordinates of the intersection the stored screen and the straight line are determined, and the point having the coordinates of the intersection point is displayed on the three-dimensional image.

Abstract: An unprocessed cluster index and its amount of parallel movement are acquired. The order of processing clusters does not matter as long as the frame is the same. Subsequently, with respect to an unprocessed vertex corresponding to this acquired cluster index, a vertex index and the weight w of this vertex are obtained. Then, according to the amount of parallel movement and weight w in the same frame, the values of coordinates of the vertex buffer are changed. Since the cluster transformation is effected by parallel movement here, the order of processing clusters does not matter, and it is thereby possible to calculate the vertex coordinates after transformation by simple multiplication and addition alone without matrix operations.

Abstract: The present invention is a system that allows a user to physically rotate a three-dimensional volumetric display enclosure with a corresponding rotation of the display contents. The rotation of the enclosure is sampled with an encoder and the display is virtually rotated by a computer maintaining the scene by an amount corresponding to the physical rotation before being rendered. This allows the user to remain in one position while viewing different parts of the displayed scene corresponding to different viewpoints. The display contents can be rotated in direct correspondence with the display enclosure or with a gain (positive or negative) that accelerates the rotation of the contents with respect to the physical rotation of the enclosure. Any display widgets in the scene, such as a virtual keyboard, can be maintained stationary with respect to the user while scene contents rotate by applying a negative rotational gain to the widgets.
