The stroke simulation device 23 includes a pressure-radius transition 22, a positive vector generation module 24, a sparse position J 26, and a touch trigger generation module 28. Pressure - radius! 2 2 is used to receive the pressure value Z, and uses a pressure conversion formula to convert the pressure value Z into a radius data α. The path conversion formula is obtained according to the relationship between the radius π and the graph shown in Fig. 2, which is expressed as: w ~ f(z) = (Μαχω) where ^/(0) = 0 /(1) = Μαχυτ 0<Ζ<1 positive vector generation module 24 is used to receive the main material' and generate a positive positive vector generation module 24 according to the main position data. First, according to the main position, the nib 1 1 is located on the main position coordinate G.

Suppose Vi = (x, y), Then, the positive vector data M=(U). The density position generating module 26 is connected to the pressure-radius conversion module 22 and the positive vector generation module 24 for using the radius data... In the positive vector and direction of the main position coordinate Q, a plurality of sparse position data are generated to represent a plurality of sparse position coordinates ~. Please refer to Fig. 4. Fig. 4 shows a plurality of sparse position coordinates ~. The dense position generating module 26 uses a sparse position generating formula to generate a plurality of sparse position data. This formula is expressed as:

As shown in the figure, each major position coordinate corresponds to 10 sparse position coordinates. Please refer to Figure 6. Figure 6 is the stroke of the stroke generation module 28. A flowchart of the method 30 is generated. The stroke generation module 28 is produced by using the stroke generation method 30. The main line Z and the dense line heart ~. 〇 Assume that the main line Μ is composed of m main coordinate positions, and each main position coordinate system corresponds to the tamping density position coordinates. As shown in Fig. 5, here In the example, w = 3, and " =1 0 〇 In step 32, the stroke generation module 28 calculates the tangent vectors C and C+i of the third solid and the / + 1 position coordinates, the formula is: | 7: ; where 匕 indicates the / + 1 position coordinates, and Qiao

[a e [0?1J represents the / position coordinate. 13 1264674 In step 3 4, the stroke generation module 28 uses the Blending functions to calculate the interpolated value between the first and the i + 1 position coordinates. The mixed function is expressed as: hx( s)=2s3 -3s2+1 h2(s)=-2s3 ^-Ss2 < h3(s) = s3 -2s2 +s h4(s)= s3 -s2 0 < ^ < 1 In step 36, The stroke generation module 28 obtains a Cardinal Splines Curve having the formula: 5 = month * Λ 3 + ί · +1 * / ζ 4.

Finally, in step 38, the stroke generation module 28 calculates the intermediate coordinate position between the //th and +1 position coordinates, and joins all of the coordinate positions to produce a smooth curve. The calculation of this intermediate coordinate position is: P = S^h*C; where s3 is flying - I "2 -2 1 1 ' S = S1 C = h = - 3 3 - 2 -1 S1 0 0 1 0 _1 _ _ 1 0 0 0_ Please refer to Figure 7. Figure 7 is a schematic illustration of the strokes produced by the brushstroke generating module 28. In the stroke generation module 28, the strokes 14 1264674 generation method 30 are used to connect all the main position coordinates to draw the main lines, and all the dense position coordinates are connected to extract all the dense lines, and then the image is generated as shown in FIG. Show the strokes. In addition, the stroke generation module 28 further includes various parameter generation modules for generating different parameter settings to simulate different stroke styles. Please refer to Figure 8. Figure 8 is a schematic representation of the stroke generation module 28. The stroke generation module 28 includes a color parameter generation module 40, a rate parameter generation module 42, a rate-color parameter generation module 44, a depth parameter generation module 46, a rendering parameter generation module 48, and a break. The parameter generation module 50 and the touch color parameter generation module 52. The color parameter generating module 40 is configured to generate a color parameter corresponding to the main position data and the dense position data by a random number generating module (not shown) to determine the main line 1 and the dense line ^~Zl° The color of each point on the top. The color parameter generation module generates a color parameter using a color parameter generation formula. This formula is expressed as: 15 Γ1264674 ‘,” 丨科 7 ;::忠_更 ρ丨 + |raW〇|%(广2 - a + 1) where : where A and the system default.

The rate parameter generation module 42 uses a rate parameter generation formula to generate a rate parameter Ζ. This formula is expressed as: F 2 / (V) ^ max_3VmaxV + 2v where v represents the instantaneous rate of the stylus 10 at the main position coordinates, and vmax represents a preset maximum rate value. When writing, the pen and ink have different shades because of the different instantaneous speeds. In general, the higher the instantaneous rate, the lighter the color of the ink. Therefore, the rate-color parameter generation module 44 is operative to generate a rate-color parameter based on the color parameter and the rate parameter to present the relationship between the instantaneous rate and the ink level.

Λ II ’A ljl z value force pressure is used to generate the L St number of the group 4 ο 浅 浅 深 深 深 深 深 深 深 深 深 深 深 深 深 深 深 深 深 深 深 深 深 深 深 深 深 深 深 深 深 深 深 深 深 深 深 深 深 深 深 深 深 深 深 深 深 深 深 深 深 深 深 深 深When a soft pen such as a brush or a watercolor pen is written or painted, it usually has a lighter appearance. Therefore, the main position data will have the largest depth parameter, and the farther the distance data from the main position data has the smaller depth parameter, so that the main line 1 is the deepest, and the dense line from the main line 1 is farther. The lighter, the lower the concentration. In general, the lower the pressure, that is, the less the writing force is applied, the more noticeable the pen-feet concentration becomes, and the smaller the pressure, the less noticeable the pen-feet concentration becomes. For example, when writing with force, the concentration of the stroke is usually particularly thick and uniform, that is, almost no lightening occurs. Therefore, as described above, the deep parameter generation module 46 generates the shallow and shallow parameters based on the pressure value Z. In addition, the depth parameter generation module 46 generates a formula for generating the depth parameter 2 by using a shallow parameter 17 1264674. This formula is expressed as: -Λ)(ι_π)+Λ); where α is a constant defined by the user, and Ζ is the pressure value, and Α is the preset value of the depth parameter. Because, when the writing force is large, the concentration of the stroke will be extremely thick, and it will be very uniform, and almost no lightening will occur. Therefore, in the above formula, when the pressure value is greater than a predetermined value, the depth parameter will Is a constant. In general, both the brush and the watercolor pen will be rendered or expanded when writing and painting, so each stroke will have a different thickness. The longer the pen tip stays, the greater the rendering will be, and the render parameter generation module 48 is used to simulate this rendering phenomenon. The rendering parameter generation module 48 is configured to generate a plurality of rendering position data based on the main position data and the radius data slave to represent a plurality of rendering position coordinates. Please refer to Figure 9. Figure 9 is a schematic diagram of the % of the rendered position coordinates. Each of the main position data corresponds to a plurality of rendering position data, that is, each main position coordinate G corresponds to a plurality of rendering position coordinates %. The rendering parameter generation module 48 includes a rendering parameter 18 1264674 d for determining the distance between each of the two rendering position coordinates, and using a rendering position generation formula to generate a rendering position coordinate such that the distance from the main position coordinate α The distance between the coordinates of the far rendering position is smaller. This formula is expressed as: ^- = DV2q dt ; where this formula is developed using the finite difference method (finite difference m e t h o d ) as follows:

1 gas wide - from +gJ qi + l = + 2Dt · qM ~ 4Dtqt + IDtq^ f \ \ ^ = 7-Τ7Γ; (-4^.+(1+ 2D〇^m) a j 0 as mentioned above, In the range beyond the radius slave, the calculation of a plurality of rendering position coordinates, and the distance between the coordinates of the rendering position will gradually become smaller, and finally will approach zero. Therefore, when the stroke is formed, the brush stroke will grow outward. The phenomenon, while the growth rate will gradually slow down, and finally approach zero. According to the different settings of the rendering parameters β, the growth rate will change differently, and then present different rendering phenomena. The above is the position change of the simulation rendering phenomenon, As for the change of the color value, the above formula can also be used to obtain the color change of the color phenomenon of the rendering phenomenon. Therefore, each of the above-mentioned rendering position data corresponds to a rendering color data, and the rendering parameter generating module 48 will also Use the rendering parameter D to determine the color change between each of the two rendered color data, and use the above formula to generate the rendered color data so that the rendering location data is further away from the main location data. The smaller the difference between the color data, the lower the color will be rendered. In addition, the stroke 14 will have a discontinuous phenomenon due to the different materials of the brush or the watercolor pen, that is, some parts of the stroke 14. It will be blank, and the discontinuous parameter generation module 50 is used to simulate the discontinuity phenomenon. The discontinuous parameter generation module 50 generates an interrupt parameter corresponding to the main position data and the dense position data to determine the main position data and the sparseness. Whether the secret position data will be displayed. The discontinuous parameter generating module 50 includes a preset discontinuous parameter setting table having a plurality of discontinuous parameters corresponding to the main position data and the sparse position data. When the discontinuous parameter is the first value When the corresponding position data is displayed, when the discontinuous parameter is the second value, the corresponding position data will not be revealed. 20 1264674 Therefore, by setting the discontinuous parameter, stroke 14 Some of the position points will be blank, causing the lines to appear intermittent. The discontinuity parameter d can be expressed as: d = dTable(i) ·, where de [0 , 1] When the discontinuity parameter is 0, the position point represented by the corresponding position data will be blank, and when the discontinuity parameter is 1, the position point represented by the corresponding position data will appear. In addition to using the individual parameter generation modules described above to generate parameter settings, the stroke generation module 28 further includes a stroke color parameter generation module 52 to combine the above parameters to generate a stroke color parameter. The parameter generation module 52 is based on the color parameter A generated by the color parameter generation module 40, the rate parameter generated by the rate parameter generation module 42, the depth parameter generated by the depth parameter generation module 46, and the discontinuous parameter. The discontinuity parameter d generated by the module 50 is generated to generate a touch color parameter. The stroke color parameter generation module 52 calculates a stroke color parameter using a touch color parameter generation formula. This formula is expressed as: 21 1264674 As described above, the strokes drawn by the stylus ίο contain the main location data, and each primary location data corresponds to ^ sparse location data, and k represents the i The stroke color parameter corresponding to the jth sparse position coordinate of the main position seat ^. Please refer to the first map. The first picture is a schematic diagram of different strokes.
