Abstract

A smooth curve is represented in a graphics texture by setting the texels that are inside the curve 80 to a value greater than a predetermined threshold value for the curve 80 and the texels that are outside the curve 80 to a value of less than the threshold value for the curve 80 (or vice-versa).Such representations of two smooth curves 80, 81 are packed into a single graphics texture (the same texel space) 82 by giving each curve 80, 81 a different threshold value, setting the texel values so that they are appropriately valued with respect to each curve's threshold value, and ensuring that the positions of the threshold value contours of the two curves do not actually overlap each other in the texture.
