Description

Real three dimension Chinese character generating method for computer

The present invention relates to the generation method of real three dimension Chinese character in the computing machine, exactly, it is to utilize computer realization the plane Chinese character to be become the method for real three dimension Chinese character.

Name on office, universities and colleges, enterprise, company, the market shop front, what people saw all is to adopt artificial method sculpture shaping, forging to cast type or engrave moulding usually, plate the layer of metal material then, make the existing real stereoscopic sensation of name, seem very luxurious again, be rich in the effect of advertising art.In today that computing machine is extensively popularized, people can want this artistic Chinese character is quantized, and are applied to television advertising, video display head, colored printing on the one hand; Be applied on the other hand to control automatically in the making of real real three dimension Chinese character (comprising the processing of various copper words and engraving of various an inscription on a tablet, board and seal etc.).

By retrieval as can be known, also there is not a kind of real three dimension Chinese character generating method for computer to come out at present.

The objective of the invention is to design a kind of generation method of the computing machine real three dimension Chinese character that can control automatically.

The present invention will generate real three dimension Chinese character in computing machine, its theoretical background is:

Set up the mathematical model on real three dimension Chinese character surface, promptly use binary function

Z=h (p) p=(x, y) ∈ Ω rice is described the surface of real three dimension Chinese character, allows it satisfy:

(I)h(p)＝0，p?∈ЭΩ；

(II) isoline of h (p) is the sea-bottom contour of Ω;

(III) dullness does not subtract h (p) or dullness does not increase with the increase of p degree of depth in Ω.Wherein, Ω is Chinese character zone, plane, and the oxy plane fixes on the plane at Ω place, and the Z axle is pressed right-hand rule and determined.On how much, the curved surface on Э Ω is opened in function h (p) expression, and Э Ω is the border of Ω.For p ∈ Ω arbitrarily, h (p) expression Chinese character curved surface is at the elevation at p place.The depth d (p) of p point in the Ω of plane Chinese character zone is defined as:

d(p)＝min?p(p，q)，

Q ∈ Э Ω P (P q) is the Euclidean distance of any 2 p and q on the oxy plane, among the Ω of plane Chinese character zone the degree of depth be the sea-bottom contour of t 〉=0 be point set S (t)=p | p ∈ Ω and d (p)=t}, special S (0)=Э Ω.

Obviously, the function h (p) that satisfies above-mentioned condition has infinite a plurality of, because for t ∈ (0, max d (p)) arbitrarily, and moulding function H (t)=h (p),

P ∈ Ω wherein, d (p)=t, p ∈ Ω has infinite a plurality of.People can also can produce the peculiar real three dimension Chinese character of the style of inconceivability in the reality by the specific design of moulding function H (t) by moulding function H (t) is come real three dimension Chinese character in the simulating reality as specific design.

Real three dimension Chinese character generating method for computer of the present invention is achieved in that its concrete steps are:

1) read in the two-dimensional character outline data, and standardization;

2) ask the crestal line in Chinese character zone, and graduation is carried out in the Chinese character zone by crestal line;

3) be that the three dimension Chinese character moulding is carried out on the basis with the crestal line: triangulation is made based on each subregion of crestal line graduation in the Chinese character zone; For each node of triangulation, obtain its degree of depth, give an elevation then; On the triangulation in Chinese character zone, make the burst linear interpolation.

4) three dimension Chinese character moulding result output.

The present invention's real-life real three dimension Chinese character of simulation that can be really true to life also can produce the peculiar real three dimension Chinese character of the style of inconceivability in the actual life.It can be used for the making of artistic Chinese character in television advertising, video display head, the colored printing, produce and add the different advertising art effect of playing up of artistic Chinese character with two-dimentional half-sum two dimension, also can be used for the robotization of real-life real three dimension Chinese character (copper word) making and the robotization that real three dimension Chinese character is engraved, both alleviate producer's labour intensity, improved make efficiency again greatly.The method that the present invention states also has versatility, is suitable for any font, any font size.

The invention will be further described below with reference to accompanying drawing:

Fig. 1 is a work block diagram of the present invention

Now process box Fig. 1 is described as follows:

In reading in two-dimensional character outline data frame, the two-dimensional character outline data can be a curve data, also can be polygon data.For the former, always can be similar to, and reach any permissible accuracy with the latter.

In asking the crestal line frame in Chinese character zone, the crestal line of so-called plane Chinese character zone Ω is the track of this sampling point among the Ω, it to the distance of border Э Ω at least two points on Э Ω get.Therefore, also being crestal line sometimes is the axis.

In three dimension Chinese character moulding frame, do four things based on crestal line:

(1) selected moulding function H (t), t ∈ (0, max d (p));

p∈Ω

(2) each subregion to the graduation of Chinese character zone, the plane Ω that determined by crestal line carries out triangulation, constitutes the triangulation △ on the Ω of Chinese character zone, whole plane;

(3), give corresponding elevation in each summit of △ by moulding function H (t);

(4), make the burst linear interpolation according to the elevation on △ and the △.

In three dimension Chinese character moulding output box, with a kind of standard file format, with the data output of three dimension Chinese character moulding.

According to the method described above, just can on any computing machine, programme at an easy rate and realize, reach the purpose that generates real three dimension Chinese character on computers.

Claims (1)

1. real three dimension Chinese character generating method for computer is characterized in that its adopts the following step:

1) read in the two-dimensional character outline data, and standardization;

2) ask the crestal line in Chinese character zone, and graduation is carried out in the Chinese character zone by crestal line;

3) be that the three dimension Chinese character moulding is carried out on the basis with the crestal line: triangulation is made based on each subregion of crestal line graduation in the Chinese character zone, each node for triangulation, obtain its degree of depth, give an elevation then, on the triangulation in Chinese character zone, make the burst linear interpolation;
