摘要： Occlusal contact (14) between upper and lower virtual three-dimensional teeth (10) of a patient when the upper and lower arches are in an occlused condition are determined and displayed to the user on a user interface of a general purpose computing device. Various techniques for determining occlusal contacts are described. The areas where occlusal contact (14) occurs is displayed on the user interface in a readily perceptible manner, such as by showing the occlusal contacts in green. If the proposed set-up would result in an interpenetration of teeth in opposing arches, such locations of interpenetration are illustrated in a contrasting color or shading (e.g., red). The ability to calculate distances and display occlusal contacts in a proposed set-up assists the user in planning treatment for the patient. The process can be extended to interproximal contact detection as well. The concepts also apply to dental prosthetics, such as crowns, fillings and dentures.

摘要： A method of collision detection is provided that allows for virtual objects having arbitrary shapes to be simulated with six degrees of freedom. The collision detection method is capable of providing full body contact by detecting each intersection between a representation of a first virtual object and a representation of a second virtual object. The full-body contact may be provided as haptic rendering signals indicating the full-body contact between the two virtual objects.

摘要： A computer implemented method for simulating interactions between relatively movable objects of arbitrary shapes and sizes wherein a space to be modelled is mapped to a grid of cells each of which is a basic spatial element; a first object is mapped to a first set of grid cells representing the shape of the first object and a second object is mapped to a second set of grid cells representing the shape of the second object, movement of at least one of the objects through the modelled space is simulated by mapping the moved object to an updated set of grid cells selected to represent the shape of the moved object after a predetermined stepwise movement of the object, and movements which would result in sets of cells representing different objects including a common cell are precluded. Each basic spatial element may be a pixel or a voxel.

摘要： 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. As a result, an arbitrary point on the three-dimensional image can be designated by a simple operation.

摘要： An apparatus and method are described for performing a distance test in a ray tracing system. For example, one embodiment of a graphics processing apparatus comprises: a ray tracing traversal/intersection unit to identify two or more ray-surface intersections, each of the ray-surface intersections being assigned a unique hit point identifier (ID); and a distance testing module to disambiguate the order of the ray-surface intersections using the hit point ID if the two or more of the ray-surface intersections share the same distance.

摘要： A level of detail node may hold in a bounding volume hierarchy, an object identifier, a distance at which a transition occurs between levels of detail and a bias. When a level of detail node is encountered in the hierarchy, the distance value may be used to select a level of detail. Sometimes a different level of detail is loaded because the preferred level is not available. The different level may be marked in a register. Then for a subsequence frame, the correct level is used. A node bias may be used to override the level of detail selection is some cases.

摘要： In a graphics processing system, a bounding volume (20) representative of the volume of all or part of a scene to be rendered is defined. Then, when rendering an at least partially transparent object (21) that is within the bounding volume (20) in the scene, a rendering pass for part or all of the object (21) is performed in which the object (21) is rendered as if it were an opaque object. In the rendering pass, for at least one sampling position (23) on a surface of the object (21), the colour to be used to represent the part of the refracted scene that will be visible through the object (21) at the sampling position (23) is determined by using a view vector (24) from a viewpoint position (25) for the scene to determine a refracted view vector (26) for the sampling position (23), determining the position 28 on the bounding volume (20) intersected by the refracted view vector (26), using the intersection position (28) to determine a vector (29) to be used to sample a graphics texture that represents the colour of the surface of the bounding volume (20) in the scene, and using the determined vector (29) to sample the graphics texture to determine a colour for the sampling position (23) to be used to represent the part of the refracted scene that will be visible through the object (21) at the sampling position (23) and any other relevant information encoded in one or more channels of the texture.
