Abstract:
In a computer graphics system, a method for generating texture coordinates for a selected pixel within a triangle for a texture wrapping operation, the triangle having a plurality of vertices, the selected pixel being defined within the triangle by a plurality of barycentric coordinates, the method comprising:receiving a set of texture coordinates for each of the vertices of the triangle;receiving a plurality of barycentric coordinates associated with the selected pixel;determining a plurality of barycentric coefficients for the selected pixel from the texture coordinates of the vertices of the triangle, the barycentric coefficients being optimized to obtain a specified degree of precision, the specified degree of precision being adapted to distinguish between neighboring texture coordinates; andcomputing the texture coordinates based on the barycentric coefficients and the barycentric coordinates, wherein the texture coordinates are substantially distinct from neighboring texture coordinates.
