    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: A method is disclosed. The method includes receiving a first polygon, receiving a second polygon, determining a first distance corresponding to a distance from a first origin of the first polygon to a vertex of the second polygon, the origin of the first polygon and the vertex of the second polygon defining a direction vector, determining, along the direction vector a second distance corresponding to a distance from the first origin of the first polygon to a face of the first polygon; and detecting a collision between the first and second polygons if the second distance is greater than or equal to the first distance.

    摘要: Trimmed NURBs may be rendered on a graphics processor rather than on a central processing unit. This may greatly reduce the amount of information that needs to be sent to the graphics processor from the central processing unit, in some embodiments.

    摘要: A system to capture an image and determine a position of an object utilizes a camera. A first processing module recognizes a set of predetermined landmarks, including a first landmark and remainder landmarks, in the image. A second processing module determines an actual location of the first landmark in the image, and applies at least one filtering scheme to estimate positions of the remainder landmarks in the image. A third processing module determines a pose of the object based on the actual location of the first landmark and the estimated positions of the remainder landmarks.

    摘要: Determining a node path through a node graph includes modifying the node graph in accordance with a predetermined platform performance, performing a path finding process through the node graph to obtain the node path, determining if the platform performance has changed, adjusting the node graph to compensate for a change in the platform performance, and re-performing the path finding process through the adjusted node graph to obtain the node path.

    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.
