Abstract: An ElementSnapshot control receives an element from windows presentation foundation (WPF) that is used to render a bitmap image. A determination is made by the control whether or not the bitmap image has been previously generated. If the bitmap image has been previously generated, the control retrieves the generated bitmap. If the image has not been previously generated, the control supplies the element to a native WPF class in order to generate the bitmap of the element. The generated bitmap is then rendered into a WPF scene.

Abstract: A Container3D control generates three dimensional (3D) models within a WPF scene. The control collects the objects supplied either explicitly through an Items property or via data binding a data collection to an ItemSource property.

The 3D transform is used to determine positions in the WPF scene for each 3D model.

Abstract: Smoothing operations on a three-dimensional geometrical primitive, such as a mesh, are restricted by filtering the set of smoothing vectors to apply a user-selected restriction to the set of vectors. The user-selected restriction limits the set of smoothing vectors according to a normal of a surface corresponding to the primitive. The filtered set of vectors are applied to the primitive to smooth the primitive. Thus, smoothing may be applied proportionally to the convexity or concavity of the surface. Smoothing also may be applied to move a control point of the primitive, such as a vertex in a mesh, only in a direction parallel to the normal of the surface at that control point or perpendicular to the normal of the surface at that control point. Each control point also may be reprojected after smoothing onto the original surface along the normal of the smoothed surface, or the normal of the original surface.

Abstract: A method for use in computer graphics includes receiving data defining an explicit surface representation of three-dimensional (3D) geometry and casting a ray into the explicit surface representation. For each point where the ray intersects the explicit surface, a direction of the ray is compared to a direction of a surface normal of the explicit surface at that point, and then a count is incremented or decremented based on a first rule that uses a result of the comparison at that point. Then, for one or more voxels corresponding to the ray, data is generated for each voxel that indicates the voxel is either inside or outside of the explicit surface based on a second rule that uses a value of the count at that voxel.

Abstract: A system creates three-dimensional computer models of physical objects by displaying illumination patterns on a display device to incidentally illuminate a physical object. A video camera acquires images of the object illuminated by the patterns. The patterns can include motion and multiple colors for acquiring images with large variations in surface shading of the object. Shading values from acquired images of the object are analyzed to determine the orientation of points on the object's surface. The system evaluates the quality of acquired images and selects patterns tailored to specific attributes of objects. The points' orientations are determined by comparing the points' shading values with an illumination model or shading values acquired from a calibration shading object. A model surface is fitted to the point's orientations. Applications may utilize the model for any purpose, including creating and exchanging customized virtual objects, enhanced object tracking, and videoconferencing applications.
