It fills pixels by estimating what portion falls inside the + * outer shape, and subtracting an estimate of what portion falls inside + * the inner shape. Specifying both inner and outer values produces a + * standard "wide outline". Specifying an inner shape that falls far + * outside the outer shape allows the same shader to fill the outer + * shape entirely since pixels that fall within the outer shape are never + * inside the inner shape and so they are filled based solely on their + * coverage of the outer shape. + * + * The setup code renders this shader over the bounds of the outer + * shape (or the only shape in the case of a fill operation) and + * sets the texture 0 coordinates so that 0,0=>0,1=>1,1=>1,0 in those + * texture coordinates map to the four corners of the parallelogram. + * Similarly the texture 1 coordinates map the inner shape to the + * unit square as well, but in a different coordinate system. + * + * When viewed in the texture coordinate systems the parallelograms + * we are filling are unit squares, but the pixels have then become + * tiny parallelograms themselves. Both of the texture coordinate + * systems are affine transforms so the rate of change in X and Y + * of the texture coordinates are essentially constants and happen + * to correspond to the size and direction of the slanted sides of + * the distorted pixels relative to the "square mapped" boundary + * of the parallelograms. + * + * The shader uses the dFdx() and dFdy() functions to measure the "rate + * of change" of these texture coordinates and thus gets an accurate + * measure of the size and shape of a pixel relative to the two + * parallelograms. It then uses the bounds of the size and shape + * of a pixel to intersect with the unit square to estimate the + * coverage of the pixel. Unfortunately, without a lot more work + * to calculate the exact area of intersection between a unit + * square (the original parallelogram) and a parallelogram (the + * distorted pixel), this shader only approximates the pixel + * coverage, but emperically the estimate is very useful and + * produces visually pleasing results, if not theoretically accurate. + */ +static const char *aaPgramShaderSource = + "void main() {" + // Calculate the vectors for the "legs" of the pixel parallelogram + // for the outer parallelogram. + " vec2 oleg1 = dFdx(gl_TexCoord[0].st);" + " vec2 oleg2 = dFdy(gl_TexCoord[0].st);" + // Calculate the bounds of the distorted pixel parallelogram. + " vec2 corner = gl_TexCoord[0].st - (oleg1+oleg2)/2.0;" + " vec2 omin = min(corner, corner+oleg1);" + " omin = min(omin, corner+oleg2);" + " omin = min(omin, corner+oleg1+oleg2);" + " vec2 omax = max(corner, corner+oleg1);" + " omax = max(omax, corner+oleg2);" + " omax = max(omax, corner+oleg1+oleg2);" + // Calculate the vectors for the "legs" of the pixel parallelogram + // for the inner parallelogram. + " vec2 ileg1 = dFdx(gl_TexCoord[1].st);" + " vec2 ileg2 = dFdy(gl_TexCoord[1].st);" + // Calculate the bounds of the distorted pixel parallelogram. + " corner = gl_TexCoord[1].st - (ileg1+ileg2)/2.0;" + " vec2 imin = min(corner, corner+ileg1);" + " imin = min(imin, corner+ileg2);" + " imin = min(imin, corner+ileg1+ileg2);" + " vec2 imax = max(corner, corner+ileg1);" + " imax = max(imax, corner+ileg2);" + " imax = max(imax, corner+ileg1+ileg2);" + // Clamp the bounds of the parallelograms to the unit square to + // estimate the intersection of the pixel parallelogram with + // the unit square.
