$\frac{\&PartialD;q}{\&PartialD;t}=D{\&dtri;}^{2}q;$

Wherein this formula is to utilize method of finite difference (finite difference method) to be unfolded as follows:

$\&DoubleRightArrow;\frac{q_{i+1}\&RightArrow;q_{i-1}}{2t}=D\&CenterDot;(q_{i+1}-{2q}_i+q_{i-1})$

$\&DoubleRightArrow;q_{i+1}=q_{i-1}+{2\mathrm{Dt}\&CenterDot;q}_{i+1}-{4\mathrm{Dtq}}_i+{2\mathrm{Dtq}}_{i-1}$

$\&DoubleRightArrow;q_{i+1}=\left(\frac{1}{1-2\mathrm{Dt}}\right)({-4\mathrm{Dtq}}_i+(1+2\mathrm{Dt})q_{i-1}).$

As mentioned above, surpassing radius Scope in addition can calculate a plurality of location coordinate of playing up, and distance can diminish gradually between playing up between the location coordinate, can level off to zero at last.Therefore, when style of writing forms, can present the phenomenon that style of writing outwards increases, and rate of rise can be slow gradually, level off to zero at last.According to the different set of playing up parameter D, its rate of rise variation also has difference, and then presents the different phenomenons of playing up.

More than play up the change in location of phenomenon,, also can apply mechanically above-mentioned formula and try to achieve the change color of playing up phenomenon as for the variation of color value for simulation.Therefore, it is to play up color data corresponding to one that above-mentioned each is played up position data, can utilize equally and play up parameter D and play up parameter generating assembly 48, to determine per two change color of playing up between the color data, and it is utilize above-mentioned formula to produce and play up color data, so that littler apart from the main positions data difference of playing up between the color data of playing up position data far away that heals.Therefore, can present the thin out gradually rendering effect of color.

In addition, stroke 14 meetings are because of the material difference of writing brush or watercolor pencil, and the phenomenon that generation is interrupted, promptly some part of stroke 14 can be blank, being interrupted parameter generating assembly 50 then is to be used for simulating this interruption phenomenon.
