    • The present invention provides methods, apparatus and systems for enabling real-time lighting of 3D geometric models. While these are well-suited for all processors, these are particularly useful on low power processors typically found in PDAs, cell phones, and embedded display systems. Methods+presented utilize a preprocessing scale factor and real-time shift factor to efficiently calculate diffuse lighting intensities for the bound vertices of the geometric model. An example embodiment includes scaling first digitized data of a 3D model in a floating point datatype by a scaling factor to form scaled digitized data. The scaling factor being a proper power of two. Converting said scaled digitized data into an integer datatype forming second digitized data. Enabling a transfer of said second digitized data to a display system, and facilitating lighting and shading said second format of digitized data.

    • A computer system, method, and article of manufacture for shading graphical objects and/or displays is disclosed. A graphical geometric data structure has a plurality of vertex positions defining one or more polygons, typically triangles. In a preferred embodiment, the polygons define a wireframe representation of a geometric object. Each of the vertex positions is associated with one or more sets of vertex color information. A color table has one or more fill colors to be rendered (shaded) between two or more of the vertex positions on a rendering of the geometric object. These colors can uniformly vary between the vertices of the triangle over the entire surface. A substitute color is associated with each of the fill colors so that at least two of the fill colors are associated with the same substitute color.
    • 公开了用于阴影图形对象和/或显示器的计算机系统,方法和制品。 图形几何数据结构具有定义一个或多个多边形(通常为三角形)的多个顶点位置。 在优选实施例中,多边形限定几何对象的线框表示。 每个顶点位置与一组或多组顶点颜色信息相关联。 颜色表具有在几何对象的呈现上的两个或更多个顶点位置之间呈现(阴影)的一个或多个填充颜色。 这些颜色可以在整个表面上的三角形的顶点之间均匀地变化。 替代颜色与每个填充颜色相关联,使得至少两个填充颜色与相同的替代颜色相关联。
