摘要： A pencil-sketch image is rendered from three-dimensional (3D) data by determining a pencil-sketch texture for a polygon defined by the 3D data, projecting the polygon onto a two-dimensional surface, and mapping the pencil-sketch texture onto the polygon to render the pencil-sketch image. The pencil-sketch texture is determined by obtaining a value based on a normal vector to the polygon and a light vector between the polygon and a light source, classifying the polygon based on the value, and associating the pencil-sketch texture with the polygon based on the classification of the polygon.

摘要： A real-time digital engraving technique gives the appearance of traditional copperplate engraving. The present system accepts a 3D mesh comprising vertex data and applies a novel algorithm to generate a digital engraving image based on the mesh. The present method works on any 3D model, generates the resulting image in real-time, allows the user to dynamically change views, and does not require user intervention.

摘要： Shading a polygon includes identifying points on edges of the polygon using shading values for vertices of the polygon, connecting the points to form at least two areas within the polygon, and shading the at least two areas differently. Vertices are assigned to at least two different bins. The bins correspond to different shades. The points may be identified by identifying points on edges of the polygon having vertices assigned to different bins.

摘要： A method in a computer system includes identifying faces of a mesh which share an edge and identifying normals of vertices of the faces not included by the edge. The depth components of the normals are multiplied in camera space. When the product of multiplying the depth components of the normals has a first sign, the edge is identified as a silhouette edge.

摘要： A system may include a graphics memory, a data bus, a processor, and a vertex shader. The data bus may be operatively connected to the graphics memory. The processor may send vertex data to the graphics memory via the data bus. The vertex shader may read the vertex data from the graphics memory and may subdivide the vertex data into subdivided vertex data. The vertex shader may also write the subdivided vertex data to the graphics memory.

摘要： Motion of a user is approximated by obtaining a three-dimensional model to represent the user, tracking the motion of the user, positioning the three-dimensional model to approximate the motion of the user, and rendering a two-dimensional image from the positioned three-dimensional model. The three-dimensional model includes one or more bones. Positioning the three-dimensional model includes adjusting a position of at least one of the bones.

摘要： A two-dimensional image is rendered from data for a three-dimensional model by detecting silhouette features on the three-dimensional model based on the data, and rendering polygons and the silhouette features to produce the two-dimensional image. The silhouette features are detected by detecting edges of polygons that make up the three-dimensional model, storing coordinates of detected polygon edges in an edge list, determining which of the detected polygon edges are silhouette edges, and marking, in the edge list, detected polygon edges that are silhouette edges.

摘要： A non-photorealistic image is rendered from an original model in a process which includes selecting a normal in the original model, selecting a vector from a set of vectors, and substituting the vector for the normal to produce a non-photorealistic image corresponding to the original model. The vector may be selected from a subdivision surface that defines a set of vectors, or it may be selected from a set containing a vector pointing substantially toward a virtual light source and a parameterized vector pointing between the virtual light source and a virtual eyepoint.
