摘要： Methods for generating ground shadow and lighting effects for three-dimensional models include identifying polygon data for a three-dimensional model, generating a convex polygon around a base of the model, generating hard and soft shadow meshes in and around the base of the model, and rendering the model with the shadow meshes with a display device. Methods for generating wall shadows and lighting effects for the three dimensional models further include identifying an orientation and height of a polygon in the model that extends from a ground surface in a virtual environment, and rendering the model with a lighting texture applied to either the full polygon if the polygon height is less than a threshold height or to only a portion of the polygon below the threshold height if the polygon exceeds the threshold height.

摘要： A graphics display system for driver information and driver assistance applications generates controllable and dynamic graphical effects in conjunction with 3D visualization of maps. The system generates a display of a map in a 3D virtual environment that responds to the environment changes in a dynamic and visually intuitive manner for a vehicle operator. The system processes environment information, including lighting condition, weather condition, and other data acquired from different sensors in the vehicle such as cameras and lighting sensors, or through networked information services. The graphics display can be integrated with different driver information and driver assistance system embodiments including mobile platforms, in-vehicle information systems, web platforms, and PC systems.

摘要： A method of generating three-dimensional graphics enables the generation of performance and quality balanced sun position sensitive soft shadows for objects including three- dimensional models of buildings. The method includes identification of both convex and concave object shapes for the generation of the soft shadow meshes and the modification of the soft shadow meshes based on the position of a light source in a three-dimensional virtual environment to generate realistic shadow graphics including shadows that change shape in response to movement of the light source.

摘要： In one embodiment, a method for generating textured graphics includes identifying border colors of pixels around two texture images and generating arrangements of border texels from the border colors that are positioned next to the two images in a texture atlas. The method includes generating mip-maps of the texture atlas with texels in the jump level assigned with the border color of the corresponding textures in the full-resolution texture atlas instead of the averaged color of the textures that would be assigned using a traditional mip-map process. The method includes storing the texture atlas including the two texture images and the border texels in a memory for use in generating repeated textures on an object in a virtual environment using at least one of the texture images with a mip-map without seam artifacts between the repeated textures.

摘要： A method for generating three-dimensional graphics includes generating a virtual environment in a server including a first object, second object and a direct illumination source. The method includes generating a virtual point light (VPL) in the virtual environment at an intersection between a ray from the direct illumination source and the first object, and sending data corresponding to the VPL to a client computing device through a data network. The method includes generating an illumination of the second object in the virtual environment with the VPL received from the server, and displaying the illuminated second object.
