Abstract
The present invention provides a method and a device for generating texture coordinates for a selected pixel within a triangle for a texture wrapping operation. The selected pixel is defined within the triangle by a plurality of barycentric coordinates. The method includes receiving a set of texture coordinates for each of the vertices of the triangle and receiving a plurality of barycentric coordinates associated with the selected pixel. The method further includes determining a plurality of barycentric coefficients for the selected pixel from the texture coordinates of the vertices of the triangle. The barycentric coefficients are optimized to obtain a specified degree of precision, which is adapted to distinguish between neighboring texture coordinates. In addition, the method includes computing the texture coordinates based on the barycentric coefficients and the barycentric coordinates, wherein the texture coordinates are substantially distinct from neighboring texture coordinates.
