  • Single constraint at a time (SCAAT) tracking of a virtual reality (VR) display
    Patent number: 7657079
    Abstract: 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.

  • Apparatus and method for rendering a video image as a texture using multiple levels of resolution of the video image
    Patent number: 7436411
    Abstract: A method and apparatus to generate one or more graphics textures of a video image, wherein graphics textures have differing resolutions, and to render the video image as a graphics texture using the one or more graphics textures of differing resolutions. The one or more graphics textures have different resolutions, for example, a base resolution and one or more scaled resolutions. The graphics texture may be rendered and displayed on a surface of a multi-dimensional graphics object that may be manipulated on a display.

  • Real-time digital three dimensional engraving
    Patent number: 7274372
    Abstract: 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.

  • Shading of images using texture
    Patent number: 7245305
    Abstract: Colors are obtained and used to shade two-dimensional non-photo realistic images of three-dimensional models. The colors are stored as texels in texture maps. The texels are chosen to shade the images based on their orientation in a scene. The colors may be obtained once, in a pre-rendering process. The colors may then be selected in a run-time process.

  • Shading polygons from a three-dimensional model
    Patent number: 7190374
    Abstract: 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.

  • Method and apparatus for adding real-time primitives
    Patent number: 7123265
    Abstract: A method of adding primitives in real time to a model to produce a non-photorealistic rendering (NPR) of a model includes storing attribute data for each one of the primitives. A ring buffer is provided, having at least one stage, for each vertex of the model which is to have a primitive. Within each ring buffer, data is stored representative of a direction of each one of the primitives. Information is retrieved from the ring buffer by using a pointer, wherein the pointer is incremented and iterated over each stage of the ring buffer.

  • Approximating motion using a three-dimensional model
    Patent number: 7116330
    Abstract: 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.

  • Rendering a silhouette edge
    Patent number: 7113191
    Abstract: A silhouette edge is rendered in a display format that corresponds to a geometry of a three-dimensional model. An angle between the silhouette edge and an adjacent silhouette edge in the image is determined, and the display format for the silhouette edge is selected based on the angle. Texture mapping is used to generate the silhouette edge in the display format.
