摘要： Disclosed are an image editing user interface system and method. The system includes one or more computers with one or more graphical user interfaces, and a receiving process for receiving one or more rendered two dimensional images on the computer graphical user interface. Each two dimensional image represents reflected light from a lit three dimensional object model, and the reflective light at each point of the two dimensional image corresponds to an object point on the three dimensional object model. The system further includes a changing process for changing a portion of the two dimensional image by changing the light intensity at a set of one or more points on the two dimensional image. The change in light intensity at the set of points causes a change in the three dimensional model to correspond to the change in the light intensity.

摘要： A method, system, and computer program product for adjusting a unit image area within an input image according to information importance within the unit area. An image receiver configured to receive the input image. An image warper is coupled to an importance map as is configured to generate a warped image such that regions of higher importance in the input image are expanded in the warped image and regions of lower importance in the input image are compressed in the warped image. The importance map is configured to delineate the regions of higher importance and the regions of lower importance in the input image. Texture coordinates may also be warped in a similar manner. Thus, the image is unwarped automatically by modern graphics adapters having texture mapping capabilities.

摘要： Methods and apparatus solving problems of polygonal approximations of isosurfaces extracted from uniformly sampled volumes increasing in size due to the availability of higher resolution imaging techniques. The large number of primitives represented hinders the interactive exploration of the dataset. Examples of methods are provided for adaptive isosurface extraction that are generally easy to implement and allows the user to decide the degree of adaptivity as well as the choice of isosurface extraction algorithm. The extraction of the isosurface is optimized by warping the volume. In a warped volume, areas of importance (e.g. containing significant details) are inflated while unimportant ones are contracted. Once the volume is warped, any extraction algorithm can be applied. The extracted mesh is subsequently unwarped such that the warped areas are rescaled to their initial proportions. The resulting isosurface is represented by a mesh that is more densely sampled in regions decided as important.
摘要翻译：方法和装置解决由于更高分辨率成像技术的可用性而从均匀采样体积提高的等值面的多边形逼近的问题。代表的大量原语阻碍了数据集的交互式探索。提供了通常易于实现的自适应等值面提取的方法的示例，并且允许用户决定自适应度以及等面提取算法的选择。通过扭曲体积来优化等值面的提取。在扭曲的数量中，重要的领域（例如包含重要的细节）被膨胀，而不重要的领域是合同的。一旦音量变形，就可以应用任何提取算法。提取的网格随后被取代，使得翘曲区域被重新缩放到其初始比例。所得到的等值面由在被确定为重要的区域中更密集地采样的网格表示。

摘要： Disclosed are methods and apparatus for obtaining the shape of an object by observing silhouettes of the object. At least one point light source is placed in front of the object, thereby casting a shadow of the object on a translucent panel that is placed behind the object. A camera, or other imaging device, captures an image of the shadow from behind the translucent panel. The object's full silhouette is obtained from the image of the shadow as the region of the shadow is substantially darker than the region outside of the shadow. The full silhouette thus obtained may be processed by any suitable shape from silhouette algorithm, and thus objects are not limited in topological type. A color image of the object can optionally be obtained simultaneously with the shadow image using a camera placed on the same side of the object as the light source. Multiple silhouettes can be captured for one object position, reducing the number of rotations needed on a turntable system, and reducing the post-processing needed to register geometries obtained from multiple different positions.

摘要： A method and apparatus are disclosed for finding a triangle mesh that interpolates a set of points obtained from a scanning system. A ball-pivoting algorithm computes a triangle mesh interpolating a given point cloud. The disclosed ball-pivoting algorithm triangulates a set of points by “rolling” a ball of radius r on the point cloud. The points are surface samples acquired with multiple range scans of an object. The ball-pivoting algorithm starts with a seed triangle, and pivots the ball of a given radius, r, around an edge of the triangle. During the pivoting operation, the ball revolves around the edge while keeping in contact with the edge's endpoints. The ball pivots until it touches another scan point, forming another triangle. The ball-pivoting operation continues until all reachable edges have been tried, and then starts from another seed triangle, until all scan points have been considered.

摘要： A computer system progressively stores and transmits compressed clustered multi-resolution polygonal models. The computer uses a data structure that represents a clustered multi-resolution polygonal model in n-dimensional space. The data structure has a connectivity record which encodes the connectivity information of the highest level of detail. The data structure also has a clustering record which encodes how the vertices of each level of detal are clustered to obtain the vertices of the next lower level of detail. The clustering record is organized in decreasing order of level of detail. The data structure also has a data record with information describing the vertex positions of the levels of detail, and optionally the corresponding properties. The fields of the data record are organized in increasing order of level of detail. The system also includes ways for creating this data structure from a clustered multi-resolution polygonal model, transmitting this information between computers, and compressing and decompressing this transmitted information.

摘要： A computer system stores and transmits compressed simple triangular meshes. The computer uses a data structure that represents a simple triangular mesh in n-dimensional space. The data structure has a table of vertex runs, a table of triangle runs, zero or more marching records, which provide the connectivity information of the triangular mesh. The data structure also has zero or more associated data records that include the geometric information of the triangular mesh. The table of triangle runs and the marching record have information that describes how to construct a triangular mesh (therefore, the polygon vertices and the boundary edges). The table of vertex runs describes a vertex spanning tree that provides additional connectivity information to construct the triangular mesh from the polygon. The associated data record determines the exact position of the triangular mesh in space. The system also includes ways for creating this data structure from a simple triangular mesh, transmitting this information between computers, and compressing and decompressing this transmitted information.

摘要： Methods, structures and systems for encoding and decoding isosurface data. An encoder process takes volume data and an isolevel as input and produces compressed isosurface data as output. The compressed isosurface data produced by an encoder process is composed of an occupancy image record, an optional intersection points record, and an optional normal vectors record. An occupancy image is compressed with a context-based arithmetic encoder. Compressed isosurface data can be stored in a data storage device or transmitted through a communication medium to a remote computer system, where the decoder process is executed. The decoder processes take compressed surface data as input and produce surface data as output. The decoder processes first reconstructs the occupancy image by decoding the occupancy image record. An in-core isosurface decoder process produces a polygon mesh as a surface representation. An out-of-core isosurface decoder process produces a set of oriented points as a surface representation.
