Abstract
A texture procedure allows the rendering of curve bounded objects to a graphics display device directly from a high level curve-based description. The method comprises receiving a curve-based description of the graphics object and dividing the graphics object into a rectangular mesh of texels. Each texel is then detailed by defining a combination of curved geometry functions and a boolean function. These function are then evaluated for each pixel of the graphics display device thereby rendering the graphics object to a graphics display. The texture procedure features include being procedural based and not image-based. This allows a rendering with continued accuracy even under arbitrary magnification conditions. Furthermore, the texture procedure is defined as such that will allow it to function using conventional tri-linear interpolation hardware.
