| <P> |
| This class creates a RenderedImage in conformance to the one |
| defined for the feTurbulence filter of the SVG specification. What |
| follows is my high-level description of how the noise is generated. |
| This is not contained in the SVG spec, just the algorithm for |
| doing it. This is provided in the hope that someone will figure |
| out a clever way to accelerate parts of the function. |
| |
| gradient contains a long list of random unit vectors. For each |
| point we are to generate noise for we do two things. first we use |
| the latticeSelector to 'co-mingle' the integer portions of x and y |
| (this allows us to have a one-dimensional array of gradients that |
| appears 2 dimensional, by using the co-mingled index). |
| |
| We do this for [x,y], [x+1,y], [x,y+1], and [x+1, y+1], this gives |
| us the four gradient vectors that surround the point (b00, b10, ...) |
| |
| Next we construct the four vectors from the grid points (where the |
| gradient vectors are defined) [these are rx0, rx1, ry0, ry1]. |
| |
| We then take the dot product between the gradient vectors and the |
| grid point vectors (this gives the portion of the grid point vector |
| that projects along the gradient vector for each grid point). |
| These four dot projects are then combined with linear interpolation. |
| The weight factor for the linear combination is the result of applying |
| the 's' curve function to the fractional part of x and y (rx0, ry0). |
| The S curve function get's it's name because it looks a bit like as |
| 'S' from 0->1. |
